Explain data independence, Database Management System

Assignment Help:

Explain data independence ?

Data independence is the capacity to modify the schema at one stage of a database system without having to change the schema at the further level. The three-schema architecture permits the feature of data independence. Data independence occurs since while the schema is changed at a few level, the schema at the further level remains unchanged; only the mapping among the two levels is changed.
