The user could create a suitable structure for the data beforehand, to place the information in the database that the DBMS is managing. The Database Management System removed the trouble of manually locating data, and having to go through it. Meanwhile database management systems are usually accessed in a client-server manner, where the database client and the server are located on different machines (in a local area network). Some DBMS cover more than one entry in these categories, e.g., supporting multiple query languages. This system can be categorized according to the database model and the type of computer that they support such as a server cluster or a mobile phone, the query language(s) that access the database, such as SQL or XQuery, performance trade-offs, such as maximum scale or maximum speed or others.

Files are stored in specific locations on the hard disk (directories). When a computer user wants to store data electronically they must do so by placing data in files.
