摘要
对数据库应用系统的通用数据维护策略进行了研究,根据传统数据维护存在的缺陷,提出了基于用户-权限的通用数据维护模型,该模型包括了数据维护流程模型的设计,实现了根据用户的不同权限灵活组装维护流程界面,并以流程为导航进行数据的细粒度管理和维护。该模型有效保证了数据库应用系统数据维护的准确性和便捷性,具有很强的通用性、扩展性和可移植性,能显著提高系统的开发效率。
The generic data maintenance strategy of database application system was researched,according to the existed shortcoming of traditional data maintenance,a user-permission based generic data maintenance metemodel was proposed,which includes the design of data maintenance process,user interface was realized according to user's different permissions flexible assembly process interface,and navigation data for the process of fine-grained management and maintenance were realized.The model effectively ensures the data accuracy and convenience for the maintenance of database application system,and highly versatile,scalability and portability,can significantly improve the system development efficiency.
