<p>When an object (18) in a primary memory based data base (2) is accessed by a user, there is created in the user process (14) an agent object (16), that contains a reference (20) to the real object (18), and appears as if it were the real object. All accesses to the data of the object (18) are performed by reading directly, via the reference (20) in the agent object, in the memory of the storage manager (4). The data accesses are performed via a generic interface (12), in the form of read and write operations towards attributes.</p> |
