Survey of Some Approaches to Distributed Data Base & Distributed File System Architecture.

摘要

This report looks at seven existing systems that illustrate a variety of approaches toward distributed data base and file management. The emphasis is on architectural design and the overall logical structure of the systems. Algorithms and unusual features are discussed where they are thought to be particularly interesting or to have an important effect on the overall system structure. The goal is to illustrate architectural tradeoffs and identify issues that may arise if a distributed data base system is incorporated into real-time tactical or process control systems. A secondary goal is to identify the range of architectures and system designs that must be provided for in a formal references model that would be useful in the design of future Distributed Data Base Management Systems (DDBMSs).
