11. DBMS-Definition Software system that is used to create, maintain, and provide controlled access to user databasesdatabase Component of DBMS:  Table (database)  Query  Form  Report  Switchboard Manager (Control)  Security (Control)  Database Splitter & Merge (Integration)

12. Database An organized collection of logically related data, usually designed to meet the information needs of multiple users in an organization (different with reporsitory).  Personal Database  Workgroup Database  Departement Database  Enterprise Database

13. DBMS Component in an Information System Model

14. Why DBMS? File Processing Approach – Database Approach Disadvantages of File Processing Approach and Advantages of Database Approach

15. Disadvantages of File Processing Approach Program-Data dependence Duplication of Data Limited Data Sharing Lenghty Development Times Excessive Program Maintenance

16. Advantages of Database Approach Program-Data independence Minimal Data Redudancy Improved Data Consistency Improved Data Sharing Increased Productivity of Application Development Enforcement of Standard Improved Data Quality

17. Cost and Risk of the Database Approach Specialized Personnel Instalation and Management Cost and Complexity Conversion Cost Need for Explicit Backup and Recovery Organizational Conflict

18. Data Description about objects, events, activities, and transaction, which don’t have any meaning or have a direct influence to the user Example: GN 0000-00 Metadata: Data that describe the properties or characteristics of end user data, and the context of that data
