This article is principally about managing and structuring the collections of data held on computers. For a fuller discussion of DBMS software, see Database management system.

A database is a structured collection of records or data that is stored in a computer system. The structure is achieved by organizing the data according to a database model. The model in most common use today is the relational model. Other models such as the hierarchical model and the network model use a more explicit representation of relationships.
