A solution for concurrency control and long transaction management in SDBMS
A solution for concurrency control and long transaction management in SDBMS
摘要
Abstract
The problem of long transactions is a significant problem in spatial database.The checkout mechanism and multi-version mechanism are two kind methods of solving the problem of long transactions. In this paper, we present a Shallow Version Management mechanism to realize multi-version mechanism in spatial database. And we introduced a increment storage and dynamic version views building method to improve efficiency of storing and consulting. We also illuminate how to resolve the problem of long transaction concurrency control in spatial database by using multi-version mechanism. At the end of this paper, we introduce some required means to version management in spatial database,like converge, compress and delete.关键词
