Introduction Database a shared collection of logically related data and its description, designed to meet the information needs of an organization. We now examine the definition of a database so that you can understand the concept fully. The database is a single, possibly large repository of data that can be used simultaneously by many departments and users. Instead of disconnected files with redundant data, all data items are integrated with a minimum amount of duplication. The database is no longer owned by one department but is a shared corporate resource. The database holds not only the organization‘s operational data, but also a description of this data. For this reason, a database is also defined as a self-describing collection of integrated records. The description of the data is known as the system catalog (or data dictionary or metadata—the ―data about data‖).
