High-Performance Persistence Framework

A system for managing an object database in response to a request issued an application, the system comprising:

• means for storing a plurality of objects in a persistent data store;
• means for linking a first object in said persistent data store to at least a second object in said persistent data store with a selective activation class;
• means for loading the first object from said persistent data store to a main memory;
• means for loading the second object from said persistent data store to said main memory, wherein if the second object is linked to the first object by said selective activation class the second object is not loaded into main memory unless the application requests it;
• and
• means for storing at least the first and second objects back into the persistent data store.

A high performance object persistence framework comprising:

• a central processing unit;
• a main memory store;
• a persistent data store comprising a plurality of stored objects;
• an object database manager, wherein the object database manager comprises an object loading component adapted to load a first stored object from said persistent data store to said main memory in response to a request from an application, and further adapted to load a second object from said persistent data store to said main memory, wherein if the second object is linked to the first object by a selective activation class the second object is not loaded into main memory unless the application requests it;
• and
• an object storage component adapted to store at least the first and second objects back into the persistent data store.
