Distributed Database Management of Local Networks

摘要

Three problems likely to be encountered in managing distributed databases on local networks are addressed: (1) architecture and environment; (2) database design; and (3) execution. It is determined that the primary goal of distributed database design is performance, for both retrieval and update. Therefore, the design must exploit the natural semantic relationships that exist among different fragments of the database. Because a distributed database management system for local networks must support a diversity of environments while maintaining a unit in design, it is proposed that an operating system abstraction be defined that serves as the standard operating environment. It is concluded that algorithms that are processing efficient are more advantageous than those that are communication efficient.
