The embedded database technology can be used for the management of MPEG-7
data under the limited resources of the mobile environment. In this case, XML document
clustering methods can be used, but in order to increase efficiency, a clustering method for
efficiently storing MPEG-7 documents is required. In this paper, an MPEG-7 document
management system that can efficiently store MPEG-7 documents in a mobile terminal is
designed. This system used Berkeley DB XML, a dedicated embedded XML database system
based on MPEG-7 data clustering method.
