....first image and later video database management systems have attracted a great deal of attention both commercially and academically because traditional database systems are not suitable to be used for multimedia data. The following are two possible approaches in developing a multimedia system [39]: a) metadata along with its associated multimedia data may be stored in a single database system, or b) multimedia data is stored in a separate file system whereas the corresponding metadata is stored in a database system. The first approach implies that databases should be redesigned to ....

....accessed and preserved in a bu er, consider the overlapping streams and prefetch the unshared data. By doing so, the system makes the overlapped streams available in the bu er for future accesses. Many researchers have addressed the issues related to the bu er management in multimedia servers [15, 7, 8]. With respect to the topic area of this paper, these studies can be grouped into two major categories : a) strategies promoting bu er sharing by using caching techniques[2] and (b) strategies focusing on client interaction (VCR like operation) to perform bu er replacement[9] Note that most of ....

....focus of other studies and this one is to devise data placement and scheduling schemes for media data that requires lower bandwidth than the transfer rate of a disk. The proposed schemes for this area can be categorized by their disk striping technique, as either fine grained or coarse grained [27, 28]. Fine grained striping works as follows: Fine grained disk striping treats M disks as one storage unit, with each IO unit (which we call segment) broken into M subunits (subsegments) each stored on a separate disk [5, 32, 35] With fine grained striping, all M disks service one request at a ....

....be excessive, since media data is voluminous and may take up too much buffer space, driving down throughput. Many studies have addressed disk arrays, where IOs have real time constraints. These schemes can be categorized by their disk striping technique, as either fine grained or coarse grained [22, 23]. Fine grained striping works as follows: Fine grained disk striping treats M disks as one storage unit, with each IO unit (which we call segment) broken into M subunits (subsegments) each stored on a separate disk [5, 25, 28] With fine grained striping, all M disks service one request at a ....

....access through indexing, data consistency through welldefined access methods, multi user access through concurrency control, and reliability through recovery mechanisms. This understanding has given rise to a significant amount of recent interest in multimedia database management systems [3, 12, 26, 31, 37]. Providing database functionality for multimedia data types presents a host of new challenges not addressed by conventional DBMS. These challenges stem from the fact that multimedia data types differ from traditional alphanumeric data in their characteristics, and hence require different ....
