%X Current database management system techniques are insufficient to  
support the management of multimedia data owing to their time-sampled  
nature. The extension of database systems to support  
multimedia applications thus requires new mechanisms to ensure the  
synchronized presentation of multimedia data streams. In order to  
flexibly and efficiently present multimedia data streams to users, media  
streams must be segmented into media objects with time constraints among  
these objects specified and maintained. In this paper, we investigate a  
framework and systematic strategies for supporting the continuous and  
synchronized retrieval and presentation of multimedia data streams  
in a multimedia database system. Specifically, we will develop: (1) a  
practical framework for specifying multimedia transactions and schedules  
and the appropriate synchronization constraints between different media  
streams; (2) multimedia transaction scheduling principles underlying the  
synchronized presentation of multimedia data streams when delay   
effects are considered; and (3) pragmatic techniques for 
multimedia transaction scheduling to support the synchronized presentation  
of multimedia data streams in object-oriented database systems.
