public class DatabasePlatform
extends oracle.toplink.internal.databaseaccess.DatabasePlatform

DatabasePlatform is private to TopLink. It encapsulates behavior specific to a database platform (eg. Oracle, Sybase, DBase), and provides protocol for TopLink to access this behavior. The behavior categories which require platform specific handling are SQL generation and sequence behavior. While database platform currently provides sequence number retrieval behaviour, this will move to a sequence manager (when it is implemented).

Since:

TOPLink/Java 1.0
