Multi-data-base concurrency control
The problem of managing heterogeneous distributed data bases is becoming an increasingly difficult problem due to an ever increasing number of different data base management systems utilized in many corporations. A multi-data-base transaction processing algorithm, based on a site protocol concurrency control mechanism, is proposed as a solution to this problem. A model of a centralized multi-data-base system is described in this study to provide a foundation for the multi-data-base transaction processing algorithm. An architecture for a distributed multi-data-base system is also presented and solutions to the problems of distributed-data dictionary and network management are proposed. The proposed multi-data-base transaction processing algorithm is shown to maintain global data-base consistency in the presence of global and permitted local transactions. The algorithm also eliminates the possibility of global-transaction deadlock. The notion of a test/production data dictionary provides a flexible and efficient means for dictionary management in a distributed multi-data-base system. The concept of a logical network provides an effective means of integrating heterogeneous networks.
