One major requirement for the multimedia DBMS is the capability to present the query result according to its spatio-temporal relationship. In conventional DBMSs, a user interface subsystem takes the responsibility for the presentation. However, for the efficient presentation of objects, it should be shared with an object manager. This paper proposes an object manager called OM2(Object Manager for Multimedia DBMS) which manages both objects and presentation information. It stores the spatio-temporal information of the multimedia object in the extended meta classes, SMC(Schema managing Classes), and creates the output schedule for the query result from the stored information. It also provides some other functionalities such as query processing, method processing and in-memory object management for the management of multimedia objects.
