Abstract
A method and apparatus are provided for storing non-persistent attributes separately from persistent attributes in a print management system. The system server may register callback functions with the object database which allow an attribute to be stored non-persistently, yet be obtained from the object database as if they were stored as one of the persistent attributes. The server attempts to retrieve the attribute from an object database. The object database may then determine whether the requested attribute has been registered as non-persistent in a separate virtual memory. If the requested attribute is registered as non-persistent, the object database invokes the callback function. Otherwise, if the requested attribute is not registered as non-persistent, the object database retrieves the information from disk using a database application program.
