A*算法只要求产生问题的全部状态空间的部分结点及关系,就可以求解问题了,搜索效率较高。当然由于A*算法中没有回溯，因此某些情况下可能会找不到正确的解过程。 -A* algorithm only requires a problem all part of the state space and the relationship between nodes, we can solve the problem, the search more efficient. Of course, as a result of A* algorithm is not retroactive, so some cases may be unable to find the correct solution of the process.

一种基于数据访问流的数据库索引优化方法该方法通过集成业务流程模型与数据模型，抽取了流程活动中包含的数据访问操作和流程的控制结构形成数据访问流，分析了数据访问流中数据访问操作的频度，为频繁数据访问操作所对应的数据项创建索引，达到改善数据访问性能的目的。实验结果表明，该方法提高了数据查询的速度。-A novel method called data-access-flow based index optimization (DAFIO) is proposed to provide automatic index select for databasein order to improve the data access performance. By integrating the data model and process model of the IT systems and getting data access flow, theDAFIO method can analyze the data access flow to find those data item which are accessed frequently, and then create indexes for these frequentitems. The experiment results show that the novel method is effective to improve the data access performance.

彩电故障信息共享系统 本程序使用Visual C++６.0编程制作信息共享系统,实现信息管理共享的自动化。由此实现了信息的增加、删除、修改、查看等功能，并且进而实现信息的安全管理，使信息的管理更加人性化，规范化。从而提高故障排除效率，提高信息利用率，有助于进一步提高了生产效率。-TV fault information sharing system of the present procedures using Visual C 6.0 programming produced information sharing system, Sharing information management automation. This realization of the information to add, delete, modify, check, and other functions, and thereby achieve information security management, information management more humane and standardized. Improve troubleshooting efficiency, improve utilization of information and help further enhance the efficiency of production.
