A Navigation-based Method for Data Maintenance
-
摘要: 提出导航图的概念,在此基础上研究导航式数据维护方法,该方法用于在数据约束关系复杂的应用系统中实现交互式的数据维护,确保了数据的正确性和完整性。Abstract: The concept of navigation chart is presented. Then a navigation based method for maintenance of related data is proposed. Through the navigation chart, it implements interactive maintenance in complex application systems and keeps data integrity. This approach has been applied in real time data processing systems.
