<OCSGySessionSQL> stores information about subscribers' Gy sessions and reservations within sessions in SQL. The Gy session table has one row for each active session. For each service, rating group and pool reservation within a session, one row is created to hold the allocation information. By default session and allocation information is kept after the session is finished providing history information about all Gy sessions.

<OCSGySessionSQL> implements the interface defined by OCSGySessionGeneric.pm which allows creating customised Gy session repositories.
