pA database is a set of tables that organizes data in accordance with a certain scheme, like one-to-many relationships. It makes use of primary keys to identify records and allows cross-references between tables. Each table has a set of attributes or fields that represent facts about data entities. Relational models, invented by E. F. “Ted” Codd in the 1970s at IBM, are the most popular database type in the present. The concept is based on normalizing data to make it more user-friendly.
