// Pointer to the main database connection used in the program. This
// pointer would normally be used for doing things as database lookups
// for user login names and passwords, getting workstation settings, etc.
// ---> IMPORTANT <---
//
// For each database object created which uses this wxDB pointer
// connection to the database, when a CommitTrans() or RollBackTrans()
// will commit or rollback EVERY object which uses this wxDB pointer.
//
// To allow each table object (those derived from wxTable) to be
// individually committed or rolled back, you MUST use a different
// instance of wxDB in the constructor of the table. Doing so creates
// more overhead, and will use more database connections (some DBs have
// connection limits...), so use connections sparringly.
//
// It is recommended that one "main" database connection be created for
// the entire program to use for READ-ONLY database accesses, but for each
// table object which will do a CommitTrans() or RollbackTrans() that a
// new wxDB object be created and used for it.
