This contrasts with received data processing systems where each diligence computer programme has direct access to the data it reads or manipulates.

When changes are made to the data representation, the metadata well-kept by the DBMS is changed but the DBMS continues to turn in 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 every(prenominal) judgment of conviction few change needs to be made to the data structure, the programs that were universe used before the change would continue to work.
