Abstract
We consider an environment in which an object-oriented database is periodically broadcast from a database server and a large collection of clients attempts to access the broadcast information selectively. Such a communication paradigm is very common under the newly emerged mobile computing environment. One key research issue in this broadcast context is to provide proper view access mechanism over the broadcast information. A mobile client, therefore, should only be able to manipulate information restricted by the view defined for the client. In this paper, a framework for supporting view access control for object-oriented databases in a broadcast environment is presented. Based on the framework, we illustrate how the view control mechanism can be applied to various database access activities and applications with different degree of access control requirements. Important issues that affect the design and performance of the view control mechanism are also illustrated and discussed in this paper.
