A database is a fully connected repository of information. "Fully Connected" is its one of the most important property that indicates that the pieces of information stored in the database are connected through some link. Every organization (e.g., university, airline, company, etc.) usually has its database or it may share it with another organization’s database. This connectivity allows the user to go from one piece of information to another piece in the same session. The database of a company represents its organization.
