Schema 
All objects (instance classes) that are created in an SAP liveCache database are assigned to an SAP liveCache schema. A schema is a combination of classes for a namespace in the OMS intermediate layer.
Integration
SAP liveCache schemas can be displayed from the Schemas user menu as follows:
DBA Cockpit: In the Performance user menu, choose the Schemas display.
liveCache Assistant: In the Performance user menu, choose the Schemas display.
You can specify additional details about the size of the SAP liveCache schema in relationships to the application (plan version).
