Control Panel

  1. Click Start, and then point to Settings.
  2. Click Control Panel.
  3. Double-click the icon that represents the settings you want to change.


A common form of distributed system in which software is split between server tasks and client tasks.  A client sends requests to a server, according to some protocol, asking for information or action, and the server responds.  This is analogous to a customer (client) who sends an order (request) on an order form to a supplier (server) who dispatches the goods and an invoice (response). The order form and invoice are part of the "protocol" used to communicate in this case.

Data Source Name (DSN)

When using ODBC, a the DSN is used to identify a particular data source.  Normally, this should be a short name for the data source, such as Orders or Accounts Payable.  For The Racing System, we use the DSN 'Race'.

Open DataBase Connectivity (ODBC)

a standard for accessing different database systems.  An application can submit statements to ODBC using the ODBC flavor of SQL. ODBC then translates these to whatever flavor the database understands.


This is the Sybase SQLAnywhere database which The Racing System uses.  It's the one file that you should back up as often as possible.


The registry is a database supplied by the operating system and provides a place for applications to store information rather then using INI files.
