// Database definitions. This module contains the Pascal definitions
// for the database tables and user types in the PODMS database.
//
// NOTE: If you add a new table, then do the following:
//
//  1) Add any new user definable data types
//  2) Define the database definition
//  3) Add entries PODMS_KEYS (if primary keys is an auto-created integer)
//  4) Add entries to KeysRecord record (if step 3 was performed)
//  5) Update TDSThread.LoadKeys (if step 3 was performed)
//  6) Update TDSThread.GetNewIntegerKey (if step 3 was performed)
//  7) Update TDSThread.ReadLastKeyValue (if step 3 was performed)
//  8) Add the entry to EPODMS_TABLE_TYPE enum (PODMS Constants type library)
//  9) Add the entry to the PODMS_TABLE record
// 10) Update the TableName function (see dbfuncs.pas)
// 11) Update the PODMS Constants type library to add the columns to the
//     enumerator, e.g. see EAS_TRANSACTIONS
