The Design And Development Of The Copies Of Software Of DB2 Database Subsystem

Now enterprises becoming increasingly dependent the information technology, and the loss of the database system' data would jeopardize the enterprise's competitive position and credibility, to the enterprise caused huge losses. Therefore, the protection of databases become the most important component. In enterprise-class management information system, the most valuable is the data, not the hardware or system software.DB2 is a relational database management system, and it's functions powerful , performance excellence, large corporate customers chose DB2 database products as a database platform. The demand of DB2 database users's data protection is very extensive."THE automatic online database backup system" of Shandong Darewaycomputer software Company did not provide IBM's DB2 database backup support. The author complete the software of DB2 database backup subsystem,this work include requirement analysis, system design, Development work, the subsystem was integrated into the new version backup software.This paper analyzes the background of system development ,detailed analyzes business requirement of DB2 database backup subsystem , expatiate the major problems of the subsystem, design ideas . The main elements are as follows :By analyzing DB2 database backup subsystem, This paper summed up the workflow of DB2 database backup subsystem, Under the workflow analysis of the system functional requirements. Based on the system functional requirements , give them the solutions. Formation of the system design project.Due to paper length limitations, This paper only introduce the most representative technology of the DB2 database backup module.The DB2 database backup subsystems' s functions more reasonable, operation stable , improve the application scope of the Dareway online database backup system , made up the deficiencies of the original system , Obtained the Dareway company' s affirmation.
