There is still a great deal of controversy about the best way to approach database design for object-oriented systems. SQL is used to describe the data. All the three managers can view the database as per their needs. A view may be a subset of the database or it may contain virtual data that is derived from the database files but is not explicitly stored. File processing systems was an early attempt to computerize the manual filing system that we are all familiar with. A database always takes care of its information because information is always helpful for whatever work we do. The Database is a shared collection of logically related data, designed to meet the information needs of an organization.
