This webfolder provides context and specs which are a technical plan for continuing development of digital archives for United States Masters Swimming, Inc. The current version of the RFP is at www.SwimGold.org/committee/rfp/files.htm
The principles underlying our plan are these:
Our minimal requirements are these:
The archives currently consist of 6,531 webpages with 256,338 links connecting them (as of 2/13/02). All databases are internally consistent and up to date (with the exception of records). The database is managed under program control, not human labor (although research and some data preparation is still labor intensive). All of the systems development work was done with volunteer labor and donated professional services. USMS has never had to pay for an internet server or for programming related to our archives.
Our most difficult technical accomplishment has been to create and implement a "permanent swimmer id" which enables us to link together all the information we have on any one person despite name changes due to marriage, preferences which change from year to year, and, simply, errors. There are 11,876 people whose information is now tracked by this means (as of 2/13/02). Each year we receive approximately 20,000 new records of information for individuals plus additional information on relays. Information on individuals requires the addition of approximately 600 new names/ages to our list of permanent swimmer ids at each of three seasons each year. At present, we do not identify relay information with the swimmer id.
At present our digital archive system is comprised of 8398 files in 145 folders requiring 181mb of storage. In addition, we have 69 database tables with 83mb of data (?) and one file of programs for maintaining our archives (4mb).
It is our job now to move forward with thoughtful and orderly planning and conversion so that this work is integrated into USMS in an institutional way and so that nothing is lost. The goals of the History and Archive Committee by convention next year (Sept., 2002) are to have our databases all in conventional (text) formats and to have a user interface for the maintenance system so that people other than the creator can use it.
This could be achieved by many different strategies. It is our feeling that ultimately maintenance of our information should be done on the web, so it would be preferable that all work be done in a way that will transfer to the web in the easiest possible way. We should employ technologies that help us prepare for transfer to the web. In the meantime, our work can be done from a CD which allows us to closely control distribution of any sensitive files. The implementation of this could mean that all screen forms will be expressed in a format whereby they can be compiled either for Windows or for HTML. Minimal achievement in this regard will mean that they will be completed in either Windows or HTML. Possibly our screen forms will be completed in both, but only one format is required for this consultancy.
So, we have 3 fixes at this point: text files as source data including comma delimited for databases and text vectors for narrative information, Windows and/or HTML and/or Javascript/Jscript for screens, and APL as the language that our current maintenance system is written in.
We will keep in mind the desireability of completing all conversion work so that the systems assets of the H&A Committee can be used in 3 different environments,
All systems require ongoing maintenance, so it is not assumed there will be no future work required. But, it is hoped that the future maintenance work can be done by Carl and/or other members of the 3 related committees on a volunteer basis (H&A, R&T, Computer On-Line). Future maintenance will be an important consideration in awarding this contract.
Should USMS ever decide to convert to a permanent registration number or
code, a great deal of the work in preparing for that transfer may have been
done in this effort. Meanwhile, a permanent swimmer id is essential for
maintenance of our archives.
The Vision
Our vision is far greater than the scope of this RFP, but it seems
useful to articulate our vision as context for proposals.
Miscrosoft has said there are four core languages that will be on all computers: C#, C++, VB/VBScript, and Javascript/Jscript. We are recommending that H&A shift emphasis from APL to Javascript because Javascript will be in every modern Windows based computer on the planet and will be overwhelmingly pervasive on the Internet. We intend to simplify use of Javascript by creating a scripting language that will use procedures written in Javascript and sometimes in other languages. Use of other languages is especially sensible where fully functional code is already written in another language that can be used from Javascript. This includes fully functional code that has already been written in APL to manage USMS archives.
We're making progress in figuring out how to move History & Archives systems to become more "conventional" in accord with the HOD mandate from Louisville convention. Some of our ideas may not be sufficiently far along for implementation, but we thought it would be useful to articulate them as best we can today. What we have in mind is a scripting language that will provide utilities and that can be used from Access, C++, Javascript or whatever environment one chooses. We think it important that whatever we create be able to run either on the Internet or on one's home computer without an Internet connection. When running on the internet, it should run on a zero footprint basis, that is, requiring no installation; nothing will need to be installed on your hard drive. Our vision is that this will satisfy requirements for Top Ten processing software and other LMSC's, and it may lead the way to a future suite of programs for processing Top Ten by the R&T Committee. We first named it TTSscript, but it's easier to say TScript, so that's it's name now. It will be similar to Javascript, but far simpler. (Javascript is Microsoft's implementation of Javascript, freshly written to the same specs to avoid Sun's refusal to allow Microsoft to use the name Java in any form).
TScript will be a "very high level, very small" programming language. It will be designed to create reports, forms for data entry, and to do batch processing. It is intended to increase the productivity of programmers while being simple enough for use by non-programmers.
TScript will be built on Javascript, but I hope it will be so simple there is no need for anyone to understand Javascript to use TScript. TScript will be our way of making our software run both on the internet and in your home computer and it will allow USMS people to modify programs. We will create TScript as a special way of doing things in USMS and anytime we want to extend it we will do it in the Javascript way.
People who have used scripting languages like HTML will have no trouble using TScript. Also, people who are familiar with command line processing will have no trouble. Newcomers to programming may find it a bit of a challenge at first, but help will be available. And, a program will be developed that will write scripts according to the users specifications.
TScript is not designed to be a complete language. Instead,
it is designed to empower users of other languages and databases
by making available to them utilities written in other languages,
including APL. One of the benefits of TScript is that programs
written in it will run either on the internet or in a standalone
computer under Windows. TScript programs will also be able to run
in a home computer augmented by data available from the Internet.
About APL
USMS digital archives are stored in an unadorned state.
In other words, they have no enhancement that represents a commitment to any computer language or technology
(except for some simple html enhancement).
We process our archives for on-line presentation using a language called APL. This language has been chosen because it is a very powerful language and the Chairman of the H&A Committee (Carl House) is skilled with it. Ray Polivka [polivkar@juno.com] taught APL internally at IBM for 20 years and since retirement from IBM teaches APL to employees of other corporations. When asked for some words on APL, he offered this. "APL is especially effective not only because of its rich and sophisticated mathematical facilities but also because of its conciseness and consistency. These last characteristics are rare in programming languages. Its original design was done with the user and the application developer in mind. This makes APL a very fine prototyping tool. Today a programmer or nonprogrammer user can write an APL program and run it on a vast range of computers from large mainframes, servers to the smallest PCs under a variety of operating systems such as Windows XP-9x, 3.1 DOS, OS/2, Linux, Unix, MVT, MFT, Solaris. All of that is transparent to the APL program. Yes, of course when there is particular hardware to be used that is factored in gracefully. The APL world is a dynamic place today." Ray goes on to say "From my personal experience, I can tell you that there is APL use at IBM, Massachusetts General, Lincoln Life, Connecticut General, Morgan Stanley, Hartford Life, ICGM, AllState, and Cognos." Carl adds SoftMed Systems, Pacific Life, Ryder Systems, CheckFree, The Rouse Company, and Prudential Financial.
Microsoft announced on February 13 the availability of software it has spent $2 billion developing. This software focusses on the Internet and predictions are it will change life in America. An example of its use is this: When you are driving home during rush hour, the navigational system in your car will be able to check current driving conditions to find your fastest way home.
Microsoft has announced that this software will allow developers to work in any of 20 specific languages. The languages are listed alphabetically, so APL is first on the list.

Web Servers
USMS prefers that our archives be hosted on the same server used by USMS.org.
We maintain a permanent SwimmerID for each of the approximately 12,000 people who are included in our archives. We have a list of every name/age with which they've been recorded. When new information comes in, all those contained in the list are assigned the permanent SwimmerID. All names/ages which are not in our list are matched either in a guessing process or by serious research. Some errors are certain to persist in this process, but it is the best we can do until USMS Registration and Top Ten are administered with a universal permanent swimmer id.
The SwimmerID has three parts. The first 3 characters are the 3 most
obscure letters of the last name. Characters 4 and 5 are birthyear.
Characters 6 and 7 are birthday encoded with a function called "Date_code".
This is documented in the function "SWIMMERID".
In our databases, these three fields are called: Alphacode, Birthyear and Birthday.
Database connectivity
USMS has several important database systems.
The H&A Committee uses database and website maitenance tools created by Carl House using the language APL. These tools were required because our databases had no key field and included many misspellings, name changes, and other errors. We also knew there would be great variety in the nature of information we gathered and that it might be vast in quantity. We felt it important that our archives be stored with the least possible enhancement (raw content) and that our processing not be labor intensive. These are a set of special conditions that are not common to most database or website creation tasks.
There are few other users of APL in USMS, and volunteer labor is very important to how USMS gets things done. Therefore, we are committed to using tools that are in widespread use in USMS whenever we can.
The archives catalogue is a good example.
That project is new. There are other tools available that will do the job.
There is, therefore, no need to use APL.
At present, the tool we are using is Excel,
but that is likely to change in the future.
At the present time, the APL compiler is
reading the Excel file and creating an html page (without any importing or exporting).
So, existing APL capability is being used to display the catalogue on-line,
but APL is not being used to create or maintain the catalogue.
APL performs a similar function in reading
Gail Roper's Excel file of Olympians who have swum USMS and
Mary Beth Windrath's file of Nat.Champ. meet results
and Sandi Rousseau's file showing who has what Nat. Champ. meet results.
In all 4 of these cases, the APL webpage compiler is reading the file
exactly as it is being given to us without any importing or exporting.
/committee/archives.htm - Barbara Dunbar's archives catalogue.
/committee/olympians.htm - Gail Roper's list of Olympians in USMS.
/committee/champresults.htm - Sandi Rousseau's list of Nat. Champ. results.
/committee/natsdb.htm - Mary Beth Windrath's file of Nat. Champ. results
We've now moved all these items into one place and have hopes
that Barbara will be able to improve how they are organized
and that she will lead the creation of maintenance procedures for these databases and tables and catalogues.
(She will need technical help.)

Making Data Available
Currently data is available from static files and also
in response to specific requests.
Clearly, in the future we should make our data available
from a web server in response to user query without human intervention.
Proposals in response to this RFP may include such a provision,
but this subject is not a required item in the RFP.
We believe that others in USMS are well able to satisfy this desire.
Webpage Design
The template we are using for presenting information on the web
is a separate subject from any issues related to how information
is gathered, improved and stored. In order to make this point,
on February 10 we changed most of our archive webpages so that
they look very similar to the template used on the USMS.org website.
On February 13 our on-line archives were changed back to the template we have been using
(at the request of the USMS Webmaster).
But, in this experiment we learned a few things.
One thing we learned is that there will be some adaptation required if we wish to make the USMS template work for our archives.
Here's how our experiment went. Our digital archives are organized in 35 folders. 26 of these folders readily accepted the USMS.org template. 9 folders will take a little more work to accept the USMS.org template because they have many pages and all pages are at the same level in menus. This can be solved by organizing swims by gender and age group, LMSC's by Zone and Clubs by LMSC to form two levels of menu structure.
We are gathering data in forms that do not require any particular presentation style or technology. The fact that it was easy to convert from the SwimGold style of presentation to the USMS.org style of presentation should establish that archive gathering & cleansing and archive presentation are different subjects, though we care deeply about both subjects.
Here are some specific requirements for the template we can use for presentation on the internet.
The following was written by Leo Letendre and seems useful as a USMS convention.
"I have written a number of programs which need to store time including 3 or
4 for swimming. When a data type has been available within the language
which is time based (for example the VAX had a 64 bit date/time format with
resolution of 100 microseconds) I have used that. On systems that do not
have a time data type, I have generally found it easier to store it as
either a real number or a string that looks like a real number. That is, it
was stored in the form of 123.45 for 1:23.45. The reason I chose this
format is based upon ease of manipulation. Yes, I had to remove any
formatting when accepting input and add it when I printed the time but
everything else in between was simplified. If I had to convert from real
number to string, string to real number, convert from SCY to SCM, sort, etc,
I did not have to worry about formatting (eg. for a 100 free, making sure
the 59.99 had a : in from if it all of the time so that it would sort
correctly). As far as someone looking at the internal representation I
would suggest that the number of people who really need to worry about it is
limited and should be able to read 123.45 for what it is." (Leo Letendre)
Future maintenance
It is expected that future maintenance will be provided by the "Client"
with significant contribution to documentation by "Users".
We will also cooperate with others in USMS who may develop
software in other languages which can supplement or replace
our current software.
Other
URLs (uniform resource locators, a web site's address)
and web page names should remain constant as much as possible
so that search engines, links, and "favorite places" continue to work.
APL computer systems in use by the H&A Committee use proprietary utilities and subsystems that have been developed by Carl House during his several decades of consultancy in development economics. Any improvements or adaptations to these utilities to aid in their use by USMS does not constitute a change in ownership. Permission is granted to USMS for the use of any of these utilities and subsystems for as long as USMS wishes, including the waiving of any license fees that might be required by Carl House or his assigns now or in the future for the use of these proprietary systems by parties other than USMS. If in this consultancy, it is proposed that any other proprietary software is to be used, then any required license fees or other payments must be part of the cost proposal (bid). If any liability for future license fees might be incurred by USMS in this consultancy, then the consultant is required to give appropriate notice to USMS as soon as such liability becomes a possibility. USMS reserves the right to refuse to allow the use of any software that might require future license fees or royalties that is not divulged in the original cost proposal and included in the consultancy contract.
Our minimal requirements are these:
For purposes of this RFP, the following terms are defined.
The export procedure should be automated so it can be easily repeated at a later time. Maintenance of the APL files will continue while USMS develops a strategy for enterprise database management. The structure and scope of USMS digital archives will not change during the several months required to develop an enterprise database strategy, though data will be added within the current scope and structure.
The source files reside on a PC running Windows 2000 Professional and are processed with programs written in APL+Win version 4.0. It is our belief that knowledge of APL is essential to undertaking this consultancy.
Data currently stored as text vectors should become .txt files. Data stored as matrices with fixed width fields should become .csv (comma delimited files -- the data contains no commas). The new text files will be stored in the same directory structure as their web counterparts, so there will be no name conflicts. This means that the 145 folders in \SwimGold\ will be mirrored with 145 folders in \Archive\. (The actual number of folders will be less because many folders only have graphics for which no conversion is needed and other folders are only used to syncronize the local site with the server.)
Some level of documentation may be helpful to enable others to use the text files. Perhaps a catalogue in both digital and paper format is desired, but it may not be necessary if folder structure and file names are sufficient to provide documentation. The proposal should consider this. The proposal should also consider how we can be assured that the text version of the database includes all of the data items in the APL version. Control should be provided for on the number of items and perhaps on some sort of "checksum". This RFP does not require any consideration of the software needed for maintaining the database, nor for anything equivalent to a dBase header or other file control or pointer system other than whatever catalogue might be proposed.
File naming conventions will be important to making it possible that this facility and its catalogue will be self-maintaining as much as possible. The following is the naming conventions for most Top Ten files prepared for the web. All text files created in this consultancy should follow some variation of this naming scheme and the resulting naming scheme should be carefully documented and followed.
Top Ten files prepared for the web have names with 8 characters.
The ambiguity in the above paragraphs is intentional. It is intended to give the consultant latitude in proposing how best to serve USMS. It is expected that proposals will NOT be ambiguous and USMS protection rests in the comparative evaluation of proposals, in the contract procedure, and in the evaluation of deliverables.
No conversion is to be made of image files, but where they appear in SwimGold they should be copied into the corresponding folder in "Archive". Documentation of image files is not within the scope of this consultancy.
Files which must be exported are listed here. If the "#records" is zero, then it is a file of narrative data and each "file component" is a text vector. File component numbers must be offset by one as the file component structure is zero origin. Where data has fields, they are shown. Where fields have fixed width, the width is shown in parenthesis after the field name. Someday our databases will be able to have a single field to identify the swimmer (when we have a permanent swimmer id used in Registration and R&T). In anticipation of that day, exported files should place all fields that identify the swimmer last with the SwimmerID first among those. Someday in the future we will be able to truncate our databases to include only data up to the SwimmerID. In addition, the "Record" field should be eliminated from Top Ten files (4211-4227). Our APL files include a header equivalent to a dBase header. Data is always included after the header, so if a file has 120 components and 70 data items that means the header occupies the first 50 components. Further clarification will be available from the Client (H&A Chairman) during the consultancy if needed. Files in "Archive" will not match files in "SwimGold" one-to-one because "Archive" will not include some files generated from other data, some clarifying files, and, most importantly, because Top Ten core databases should organized by season (3 per year) while "SwimGold" web files are by age group and the current Top Ten APL source files are by year (4211-4227).

Deliverables
Deliverables are three in number and shall be completed in the sequence shown below.
Deliverables will be evaluated by designated USMS people within one week of delivery.
USMS will designate several evaluation people so if one person is too busy to
perform evaluation, others will do so. The H&A Chairman and Vice-Chairman
are committed that they will complete their evaluation within the one week time period.
Data
A compact disk shall be created which contains text versions of all SwimGold data.
All data shall be organized in subfolders corresponding to subfolders in SwimGold
except that the folder below root will be named "Archive" rather than "SwimGold".
This should be delivered as 3 copies as quickly as possible for review by USMS
people. At conclusion of the consultancy, ten copies will be delivered which include
software.
Software
The automated export procedure shall be written so that it senses the complete
structure and contents of SwimGold and, if it does not exist, creates "Archive".
If "Archive" already exists, the export procedure shall prepare for export
every item of data in "SwimGold" and, if it is different from the corresponding
item in "Archive", it will replace the "Archive" file. If the new file is not
different from the existing file, then it should not overwrite the old file.
This is important to protect the date time stamp on the file.
The software shall include an install procedure so that it can be used by
anyone authorized by USMS to update the "Archive" text files from the normal
backups of History & Archives data maintained by the H&A Committee
or by anyone with access to the main computer used by the H&A Committee Chairman.
The software shall include any required run time system.
The export software completed in this consultancy is expected to run
on a PC running under Windows 98 or later.
Documentation
This RFP calls for an export structure which is to a great extent self-maintaining.
However, whatever documentation is needed to install and operate the "Archive"
maintenance procedures shall be included.
Directions for Submissions of Proposals
Proposals should be delivered by April 1, 2002 to
the USMS H&A Committee Chairman
by either U.S. mail or by e-mail to
Carl House or
Carl House.
His telephone number is 561-368-7445.
An e-mail receipt will be sent confirming receipt of each proposal,
so include the appropriate e-mail address in the proposal package.
Modifying APL programs
Existing APL programs must be revised to work from text files
and to update text files automatically when they complete executing.
The Client will work with the Consultant to achieve this.
The Consultant should assume that these functions are working properly.
If any bugs or inadequacies in pre-existing programs are discovered
during this consultancy, it is the Client's job to fix them.
User interface
A user interface must be created that will permit the User(s) to
execute all functionality necessary to maintain the archives
databases and website. While most functionality already has
working APL programs, there will be some functions that
will require more work by the Client. However, any function
that will be required by the user must be provided for in
the user interface. The user interface may be entirely in
Windows, or entirely in javascript, or both. Please see
Vision.
A complete list of the top level of menus in the user interface
and the functions in each top level group will be added to
this RFP before it is made public. They will be presented
in some detail in Critical Procedures.
Deliverables
Deliverables will be provided in several stages.
The encoding of e-mail addresses to deter "harvesting" gave us an opportunity to discover how many HTML pages each major function creates or maintains. This was possible because every HTML file was changed to use encoded e-mail and the number of files uploaded after each procedure was noted. Here are the results.
qkw_Master - 3067 HTML files were changed in a
1:55 (2 hour) run and 57 minutes were required to upload the revised files.
qkw_htm_xref - 545 HTML files were changed in a
6 minute run and 14 minutes were required for upload.
TTLMSCDATA - no HTML files were changed, the run (inc. POSTTEAM) took 20 minutes.
TTDBEXPORT - 2936 HTML files were changed in a
39 minute run (inc. POSTTEAM & TTLMSCDATA) and 55 minutes were required for upload.
TTDB_HTM_INDEX - no HTML files were changed, the run took ?? minutes.
TTDB_HTM_NAMES - no HTML files were changed, the run took :03 seconds.
LMSCWebPages - 54 HTML files were changed in a
:45 second run and :30 seconds were required for upload (for the top folder only).
ServerSync - a complete ServerSync verification with no actual uploading takes about 6 minutes.
Backup - a complete backup verification with no actual copying takes about 2 minutes.

1) You mention the fact that there are 8400 files and then later list a
number of them much smaller than 8400. Maybe a bit more on the hierarchy of
the file system would be useful.
2) In a similar vein, if you are expecting the conversion to be automatic, that is start it up and walk away, you need to let people know how they can determine what type of file a given file is. That is, what handles are available as one courses through the directory structure to determine if the file contains Top Ten data, pictures, records, etc.
3) You give an example of how a Top Ten file is named yet the file name given for the Top Ten files (e.g. file name= f4211.sf) doesn't conform to the rules.
4)Do you expect files containing images to be converted to something? You list them at the end of the RFP but you really don't address them in the body of the text.
5) You use a few terms which are either APL specific or are not commonly used (any more?) such as FCN. You might want to mention what they are and why they are useful.
6) You say "Relays are probably same as received from R&T, but should be provided for." The final RFP should be specific and not leave any uncertainty on our part.
Just some quick thoughts. Keep on plugging!, Leo Letendre

I'm impressed. You did some fast work on the revision. Here are my
comments:
The RFP states "The structure and scope of USMS digital archives will not change during the several months required to develop an enterprise database strategy, though data will be added within the current scope and structure."
This seems to imply that we will be changing the structure in the future. That's not surprising. However, we're wasting our money unless we develop a plan so that such changes can easily be incorporated in the new "export tool".
Be careful when using the word "should". "Should" is not binding. If possible use the word "shall". Examples: "Data currently stored as text vectors should become .txt files. Data stored as matrices with fixed width fields should become .csv (comma delimited files -- the data contains no commas). " If we want to mandate the "requirement" we need to use "shall".
The RFP states "Some level of documentation will be needed to enable others (non-APL people) to use the text files. Perhaps a catalogue in both digital and paper format is desired, but it may not be necessary if folder structure and file names are sufficient to provide documenation. The proposal should consider this." I don't think that we should put the burden of documentation on the bidders. It appears that you have done a great job of defining the structure. I think that we can assume that anyone importing the data into a data base application will not need any information beyond the file definition that you already provided.
The RFP also states "The proposal should also consider how we can be assured that the text version of the database includes all of the data items in the APL version. Control should be provided for on the number of items and on some sort of "checksum". " I think that we may need to "brainstorm" this a little. Since you already list the number of records and file size, I'm not sure that a checksum will buy us much since I'm not sure how the bidder can checksum the existing data.
I'll spend some more time looking at the RFP tomorrow morning.

Thanks for getting the changes requested by the EC done so quickly. I
have a few comments on your RFP:
1) In the paragraph where you describe the deliverables, I think you should be more specific. It requests the text format files and this is OK. However, you say the export procedure should be automated so it can be repeated. You don't say they have to also deliver the programming that accomplishes the export procedure. Conceivably, they could charge us to redo the export each time we need to do it.
2) I would like to see more specifics on the output side of the equation. For example, you describe the current file names and formats in detail, but do not specifically give the file names and formats (with examples) for the output (you imply this). You have a somewhat indirect way of expressing things and this is OK for those of us who know what you're talking about. I am wondering if someone looking at this cold will be able to follow your meaning and deliver exactly what we're looking for.
3) You do not say that the bidders will be able to examine the APL files before they submit their bids. They will have to have some way of determining what the conversion issues will be when they put a price on it.
4) I'm somewhat uncomfortable about the documentation issue. We should specify the documentation we're looking for.
5) In what form will we be presenting the RFP? Is this to be a stand-alone document delivered in hard copy or PDF format? The reason I ask is, there is a lot of information on the web site that is not part of the RFP. By following the various links from the main RFP page, you can get into these other areas. I think we need to focus the bidders' eyes only on the RFP. You could add an appendix that points to the other information, but the demarcation of the actual RFP should be clear.
6) Do we need to include information on the bid evaluation and contract administration process in the RFP? Would this impact how bidders respond?
Hopefully, we can clear up these questions and any other people may have quickly so we can get to the actual bidding process. Thanks for all your hard work. --
Most programs can import and export data in several different formats like the *.dbf format and several text-based formats.
We have been using comma-delimited text files with success for many years. In this format each line in the text file contains all data fields in one record in the database. The different fields are separated by commas. Trailing blanks in the fields are normally omitted so that this format can handle varying field lengths and generates smaller files than a fixed-field format. One disadvantage of this format is that no commas are allowed within a field. Comma-delimited files can be viewed and edited using a text editor, or even a word processor.
The other text-based format that is widely used is the DIF (Data Interchange Format). Again, one line contains all the data fields in one record of the database except that each field is stored with trailing blanks, making delimiters (like commas) unnecessary. The position of each field in the line is always the same. The swimmers SDIF format uses this approach and is widely used by Hy-Tek.
CSV stands for Comma-Separated-Values. It is a form of a comma-delimited text file. By default, Excel sets itself up as the associated application for .csv files when installed, and any other spreadsheet application can read them as well. It's a very commonly used format for downloading data from the web. Hy-Tek's web database for swimming performance lets you download swim results in CSV format.
The USMS National Office uses a spreadsheet (Excel) as a database program to store swimmers registration data.
SQL (Structured Query Language) is an advanced language developed for relational databases that can be used to define, manipulate, display and update data. Since it was developed in the mid-1970's, SQL has been adopted by many companies as a database language standard for both mainframe and minicomputer environments. So SQL is independent of the actual database engine that is used. SQL itself is still under development and we have SQL1, SQL2, SQL3.
SQL is not a DBMS (Database management system) like dBase, Clipper, Oracle, FoxPro, or Access. This means that if your database programs are written in SQL, they have a good chance of working with any of the major DBMS systems as long as they support SQL.
Oracle is the premier enterprise database system, but their products are expensive.
SQL Server
Microsoft's SQL Server is also a widely respected enterprise database system,
but it is also very expensive.
Pervasive.SQL combines virtually all of the best database features in a single product.
It is mature, reliable, fast, inexpensive, flexible, scalable, and portable.
It is simple to use and requires virtually no maintenance or oversight.
It runs on many different platforms and operating systems,
interfaces to any computer language, and handles web accessibility (and its heavy loads) well.
It uses Microsoft's standard ODBC and OLEDB database interfaces (plus Java/JDBC and many others)
and uses the standard SQL command language.
It has numerous advanced technical features and has a very long
(almost 20-year) history of proven performance and fully backward compatible upgrades.

dBase was the first database language for personal Computers. FoxPro and Clipper are both what are called dBase dialects in that they all use the same language for procedure (program) files with each having their own little differences and enhancements.
FoxPro is now owned by Microsoft and has evolved into Visual FoxPro.
Clipper was owned until recently by Computer Associates and has a windows version called Visual Objects.
The USMS registration program (Leoware) was written in Clipper because, at the time, it was the only database program that would produce a freestanding executable (*.exe) file. The top-ten programs are written in dBase.
These database programs all store the database in dBase format (*.dbf), making them compatible as far as data interchange is concerned. However, they do not all use the same format for index files. (Index files are used for sorting).
The problem with Access, which is used by the latest Hy-Tek programs is that Microsoft does not make any attempt to keep new versions of the data files backward compatible.
Visual Basic has the capability to use database files of different formats. When Access formats are used, VBasic also suffers from the incompatibility between different versions of the Access formats. Visual Basic also supports SQL.
Access is said to not be appropriate for very large databases (over 100,000 records). It was designed as a desktop database solution, not for use on a server.
InterBase, currently owned by Borland, is sold as a commercial product. It would probably be available on the USMS server without any licensing fees. It runs on both Windows and Linux platforms.
MySQL is freely available on many Windows and Linux servers including the USMS server.
It is said to be very fast, especially for "selects".
It is probably not faster than other databases for "inserts" or "updates".

PostgreSQL
PostgreSQL's advantage is that it is free on Windows and Linux platforms
and more complete in terms of advanced SQL support than MySQL.

Databases and languages can communicate with each other through interfaces. Microsoft created "ODBC" (Open DataBase Connectivity) sometime around 1990 as a standard interface and it is still widely in use. Approximately 1997 Microsoft created "ADO" to serve as a hub for data connectivity and the interface on each side of it is called "OLEDB" (pronounced "o-lay-dee-bee"). ADO/OLEDB has distinct advantages in ease of programming over ODBC and is likely to increasingly displace ODBC in future years. ODBC, ADO and OLEDB are Windows facilities, so they help in the local computer. Equivalent interfaces may be available and/or needed on the server.
Conclusions
The SQL platform used for H&A should meet the following criteria.
