摘要
根据特殊体制的应用需求,开发基于SQL Server数据库的电子对抗装备信息管理系统。通过构建多层体系结构,实现系统功能的有效划分。利用SHA1算法对不同权限用户的密码进行加密,增强了系统的安全性。基于Petri网对系统工作流进行建模,在此基础上,利用数据仓库对装备及备件的复杂、多源信息进行一致性存储,提高了系统的可扩展性。实际应用表明,该系统实现了全面高效、安全可靠的装备和备件计算机管理。
In accordance with the special application requirements, the electronic countermeasure equipment information management system based on SQI. Server database is developed. By constructing multitier architecture, the implementation of the system function effectively divided. SHA1 algorithm is applied to encrypt on different permissions for the user's pass- word,to enhance the security of the system. Modeling on workflow system based on Petri - net consistency storage by using data warehouse on equipments and complex, multisource information of spare parts, the system's scalability is improved. Practical application shows that the system can well develop the function and carry out completely efficiently.
