7 Caching in TimesTen

Caching in TimesTen provides the ability to transfer data between an Oracle database and a TimesTen database.

You can cache data from an Oracle database in a TimesTen database by creating cache groups in TimesTen where each cache group maps to a single table in the Oracle database or to a group of tables related by foreign key constraints.

This chapter includes the following topics:

• Cache Groups
