In order to process multimedia applications which mainly use large objects, we should use database system to store and process multimedia large objects for better functionality. We can divide one large object into small component objects by modeling technique of the database system and use entire object as a single object or use by an individual component objects or by relationships to make applications more realistic as possible.
But if we store and process large and small objects together in one database system, then interference will occur among them due to their different characteristics. This leads to consider the enhancement of processing mechanism of existing database system to control the interference between large and small objects properly avoiding degradation of performance.
Up to now, existing Database Management System processes large objects such as image together with small objects under the same buffer mechanism. Under the existing approach, if we trying to process the large object such as video, audio, then we have to suffer from severe interference between large and small objects due to their heterogeneous characteristics.
This thesis proposes and describes the architecture and management of buffer system for processing multimedia objects without interference between large and small objects. New buffer management mechanism of database system for allocation, admission control, overload control dedicated to multimedia large objects are proposed.
This thesis identifies the different characteristics between large and small objects and segregates the processing between them from different buffer mechanism of STREAM buffer, and make it possible to avoid the interference and achieve effective memory space utilization by proper space management of STREAM buffer.
