- To connect to your database, you have to create a handle: this handle actually links the interface classes with the corresponding implementation classes mapped to your DBMS. This handle is implemented by the DATABASE_APPL class:
database_appl: DATABASE_APPL [ODBC]
-- Database handle.
create database_appl.login (a_name, a_psswd)
- Once your handle is created, you have to create a session manager which will allow you to manage your database; specifically, to establish a connection, disconnect and also handle errors. The class
DB_CONTROLenables your application to control the functioning and status of your database and to request any information about it.
-- Session control.
