DATABASE!!!!

A special data processing system, or part of a data processing system, which aids in the storage, manipulation, reporting, management, and control of data.The DBMS determines how data are stored and retrieved. It must address problems such as security, accuracy, consistency among different records, response time, and memory requirements. These issues are most significant for database systems on computer networks. Ever-higher processing speeds are required for efficient database management. Relational DBMSs, in which data are organized into a series of tables ("relations") that are easily reorganized for accessing data in different ways, are the most widely used today.
