摘　　要：探讨了三种数据库相关的软件开发模式,分别为并发更新模式,相似语句合并模式及插入更新模式。利用此三种模式分别可以解决并发更新丢失问题,实现功能相似语句合并统一和高性能地插入更新数据,提高程序的一致性和运行效率。文中首先提出问题,然后给出解决问题的模式,最后再对模式的应用效果加以分析。三种模式对于构建稳定、高效的信息系统提供方法上的支持。This paper discusses three software development modes related to database, which are concurrent update mode, similar statements merged mode and insert/update mode. Using the three modes can solve the problem of loss in concurrent updating, realize merging/unifying of statements with similar functions and inserting/updating data with high performance, and improve consistency and efficiency of programs. Firstly, this paper proposed a question, then gave a mode of solving the question, and lastly analyzed the application result of the modes. The three modes can provide a support to constructing stable and high efficient systems of information.
