数据库数据一致性及并发处理

DATA INTEGRITY OF DATA BASE AND CONCURRENT PROCESSING

在计算机网络应用软件的程序设计中 ,并发操作是一个需要认真对待的问题。结合葛洲坝水利电力集团财务公司程序设计的实例 ,从不加控制的并发存取可能会产生的错误、数据库的事务和恢复、Sybase的并发处理机制等方面讨论了数据库设计中并发操作的问题 ,最后提出了几种提高处理并发事件效率的方法。

The concurrent processing is a problem worthy to the taken seriously in the design of application software. In combination with the practical example of the software programming for the Financing Company of Ge Zhou Ba Water Conservancy and Hydropower Group,the present paper discusses the concurrent processing problem in the data base design including the possible occurrence of errors in the uncontrolled concurrent access, data base affairs and recovery and mechanism of concurrent processing for Sybase, and introduces some methods which can handle problems very effectively in the concurrent processing.
