Abstract: A method and system for hierarchical caching of objects of an ERP system is provided. A caching system comprises a server cache component that is executed by a server and a client cache component that is executed by each client of the server. The server cache component maintains a server cache at the server, and the client cache component maintains a client cache at each client. The client cache components also cache the objects in local client caches. Upon opening an object, the client cache component checks its local client cache to determine whether the object is cached. If so, then the client cache component need not retrieve the object from the server. Thus, the caching system is hierarchical in that each server and client maintains its own cache.
