These features are: centralise info management, Data independence Systems integration. In a informationbase system, the selective information is managed by the DBMS and all access to the selective information is through the DBMS providing a key to effective selective information processing. This contrasts with received info processing systems where each diligence program has direct access to the data it reads or manipulates. In the established data processing application programs, the programs usually are scope on a considerable knowledge of data anatomic structure and format. In such environment any diversify of data structure or format would require bewitch replaces to the application programs. If major changes were to be made to the data, the application programs may pauperisation to be rewritten.

In a database system, the database management system adds the interface in the midst of the application programs and the data. When changes are made t o the data representation, the metadata well! -kept by the DBMS is changed but the DBMS continues to proffer data to application programs in the previously used way. The DBMS handles the tax of transformation of data wherever necessary. This independence between the programs and the data is called data independence. Data independence is important because each judgment of conviction some change needs to be made to the data structure, the programs that were being used before the change would continue to work. To provide a high degree of data independence, a...If you want to pay back a full essay, parade it on our website: OrderCustomPaper.com
