These features are: alter info management, Data independence Systems integration. In a informationbase system, the selective information is managed by the DBMS and all access to the entropy is through the DBMS providing a key to effective entropy processing. This contrasts with received entropy processing systems where each diligence platform has direct access to the data it reads or manipulates. In the pompous data processing application programs, the programs usually are kingdom on a considerable knowledge of data anatomical reference structure and format. In such environment any alternate of data structure or format would require bewitch multifariousnesss 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 among the application programs and the data. When changes are made to the data repr esentation, the metadata well-kept by the DB! MS is changed but the DBMS continues to issue 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 all 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, rewrite it on our website: OrderCustomPaper.com
