It is difficult to support multimedia data handling capability in conventional relational DBMSs because multimedia data requires variable and very large size. In this paper, we present the extended version of 'BADA' DBMS for handling multimedia data management. In the first place, we address the extension of the database language for handling multimedia capabilities and the implementation of the language processor to support the multimedia database language. The extended database language supports the various operations such as partial retrieving, inserting, and updating of multimedia data as well as the total retrieving of that. And it has the compatibility with any application program by minimizing the modification of SQL syntax. We also describe the extension of the efficient storage system to support LOB(unstructured Large OBject) data for storing multimedia data. We newly extended the LOB manager to the storage manager of BADA storage system. The LOB manager supports the storage structure for large-volume data, and efficiently handles the LOB data without having on effect on the inherent functionalities of existing storage system.
