This dissertation reports on the investigation of the dynamic views for object database systems in support of multiple applications. It develops object views as a way to support multiple (possibly conflicting) applications on shared data, and demonstrates that dynamic views can improve the data abstractions for specific applications, enhance the security of object database systems, and provide a way to adapt views dynamically. / In this dissertation, we present a comprehensive model of object views for object database systems. This model is compatible with ODMG-93 standard. In this model, object views are characterized by view object types and view relationship types within view schemas. Object views can be derived in many different ways from the descriptions of object databases. / An object view management system and some tools are also presented in this dissertation. The management system serves as a kernel of the view system based on the object view model, and provides an application programming interface. The tools built on top of the kernel include and object view definition language and an object view manipulation language. / The investigation is carried out in two aspects: The intension of object views and the extension of object views. The intension aspect is concerned with view types, view characteristics and view relationship types. The extension aspect is concerned with view objects and their common operations. / Source: Dissertation Abstracts International, Volume: 57-04, Section: B, page: 2667. / Major Professor: Gregory A.
