Database definition classes
The database definition classes provide a means for defining queries, stored procedures, connection specifications, and logon specifications. These classes store the information that you use to access connected databases. 
AbtDatabaseConnectionSpec 
Associates a connection alias with a database manager and a specific database. Connection aliases provide a means of creating database applications independent of specific database names. This independence enables you to develop and test an application with one database, for example, and then switch to a different database for production use without having to redefine your queries. 
AbtDatabaseLogonSpec 
Associates a user ID, password, and database server with an alias. 
SQLite note: AbtDatabaseLogonSpecs are ignored since SQLite does not support the concepts of users and logon.
AbtQuerySpec 
Defines SQL statements to be passed to a database management system by the database connection classes. 
AbtStoredProcSpec 
Defines stored procedures and the input and output parameters to passed with them.
SQLite note:  Stored Procedures are not supported by SQLite
