A database is a “container” storing data such as numbers, dates or words, which can be reprocessed by computer means to produce information.
The database management system is a suite of programs that manipulates the structure of the database and directs access to the data stored in it. A database is made up of a collection of files; it is accessed through the DBMS which receives content manipulation requests and performs the necessary operations on the files. It hides the complexity of operations and offers a synthetic view of the content. The DBMS allows several users to simultaneously manipulate the content, and can offer different views on the same set of data.
