Object Management System (OMS) is a type of data management.

A large part of the data in SAP liveCache databases is managed in objects. This object data is called OMS data. OMS data is managed in containers that are assigned to precisely one persistent C++ class of the object type.

OMS data is processed in the OMS intermediate layer. You can include application logic in SAP liveCache by using DB procedures. This removes much of the load that would otherwise be needed for communication and the transfer of data.

The system keeps the OMS data pages in the data cache.
