US Patent 7555488 Prefetching and caching persistent objects

Prefetching and caching persistent objects is disclosed. The system creates a structure context used to identify a set containing a first object and other related objects. The objects have attributes, where each attribute is identified by a name. Upon a fetch of an attribute in the first object, the system also fetches related data. The related data includes other attributes in the object, and attributes in the other objects of the set having the same name as the attribute fetched for the first object.
