Integrating Distributed Homogeneous and Heterogeneous Databases: Prototypes. Volume 3.

This volume discusses key issues relating to distributed databases, and presents alternate methods for integrating them together. It is divided into four parts. The first part, Evolution Towards Strategic Applications of Databases Through Composite Information Systems, divides applications into four categories intercorporate, inter-divisional, inter-product, and inter-model. The second part, Distributed Homogenous Database systems A Comparison between Oracle and Ingres, compares commercial products in terms of the levels of transparency and independence supported by them. The third part, Achieving a Single Model for Integrating Heterogenous Databases attempts to come up with a single unified modified that encompasses both the database issue and the communication issue. In the communication area, there are two types of standards connection-oriented and connectionless. In the database area there are multiple standards suited for different environments. The fourth part, A Technical Comparison of Distributed Heterogenous Database Management Systems, describes eight systems being developed around the world. Because of the added complexity involved in translating between multiple systems and multiple data models, distributed heterogenous database systems are more complex than equivalent homogenous ones. While all of these eight systems are able to do global retrieves, their ability to perform global updates and other capabilities is varied.
