Database Management Systems help people protect their data and make sure that everyone isn't overwriting each other. For instance, if two people were to open the same excel file and both make changes, and then save it again, it would be difficult to take both of those people's changes and merge them together. A Database Management System allows you to overcome that problem.

These include defining and modifying the record structure, thetype and size of fields and the various constraints/conditions to be satisfied bythe data in each field.· Data ManipulationOnce the data structure is defined, data needs to be inserted, modified ordeleted. The functions which perform these operations are also part of theDBMS. These function can handle planned and unplanned data manipulationneeds. Planned queries are those which form part of the application.Unplanned queries are ad-hoc queries which are performed on a need basis.· Data Security & IntegrityThe DBMS contains functions which handle the security and integrity of datain the application. These can be easily invoked by the application and hencethe application programmer need not code these functions in his/herprograms.· Data Recovery & ConcurrencyRecovery of data after a system failure and concurrent access of records bymultiple users are also handled by the DBMS.· Data Dictionary MaintenanceMaintaining the Data Dictionary which contains the data definition of theapplication is also one of the functions of a DBMS.· PerformanceOptimizing the performance of the queries is one of the important functions ofa DBMS. Hence the DBMS has a set of programs forming the Query Optimizerwhich evaluates the different implementations of a query and chooses thebest among them.Thus the DBMS provides an environment that is both convenient and efficient to usewhen there is a large volume of data and many transactions to be processed.

For example, driver functions for MySQL have mysql_* prefix.
