These features are: centralised info management, Data independence Systems integration. In a informationbase system, the selective information is managed by the DBMS and all access to the info is through the DBMS providing a key to effective information processing. This contrasts with received info processing systems where e ach diligence course of study has direct access to the data it reads or manipulates. In the unoriginal data processing application programs, the programs usually are domain on a considerable knowledge of data anatomical reference structure and format. In such environment any transfer of data structure or format would require permit budges to the application programs. If major changes were to be made to the data, the application programs whitethorn pauperisation to be rewritten.

In a database system, the database management system adds the interface amongst the application programs and the data. When c hanges are made to the data representation, ! the metadata well-kept by the DBMS is changed but the DBMS continues to hand over 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 either 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, rescript it on our website: OrderCustomPaper.com
