There are views as to how users see the relevant data. Levels of abstraction include single conceptual or logical schema and the physical schema.

Database management system is a special system of data processing which is a handy aid in the manipulation, storage, management, reporting and control of data.

DBMS is basically designed to manage a large quantity of information. Data management entails both the process of defining the structure in which the information is to be stored and the provision of mechanisms for the manipulation of the data.
