Distributed Temporal Video DBMS Using Vertical Class Partitioning Technique

In this chapter, we describe our work on developing a distributed video DBMS (database management system). The video DBMS provides a temporal modeling framework for describing video data and it supports data distribution by applying vertical class partitioning techniques. Building on top of our previous work on Four-Dimensional Information Space (4DIS) - an object-oriented temporal modeling framework, we apply class partitioning techniques onto a distributed 4DIS video database system as a means for efficient query execution. A detailed cost model for query execution through vertical class partitioning is developed. The effectiveness of our class partitioning approach, in the context of the distributed 4DIS video database system, is demonstrated through the use of a running example.
