The data base approach presumes the integration of formerly separate stores of data. While this integration may or may not involve centralization of the physical data, it certainly implies an increase in data sharing among user applications and a decrease in redundant storage of identical data items. To facilitate sharing and minimize redundancy requires central control of the content of the data base. Such control addresses the form and meaning of the data items and structures in the data base rather than the actual values of the data items themselves. The management function which exercises control over the form and content of the data base is called data administration.
