The first database systems were created in the 1960s by Charles Bachman, IBM and others. They evolved into the information management systems (IMS) which made it possible to store and retrieve huge amounts of data for a broad range of purposes, from calculating inventory to supporting complicated human resources and financial accounting functions.

A database is a collection of tables that store data according to the specific scheme, for example one-to-many relationships. It utilizes primary keys to identify records and allow cross-references between tables. Each table contains a set of fields called attributes that contain information about data entities. The most widely used type of database today is a relational model developed by E. F. “Ted” Codd at IBM in the 1970s. The concept is based on normalizing data to make it simpler to use. It is also easier to update data since it does not require changing many sections of the databases.

The majority of DBMSs support a variety of databases and offer different internal and external levels of organization. The internal level is concerned with costs, scalability, and other operational concerns such as the design of the database’s physical storage. The external level is the representation of the database on user interfaces and applications. It may include a mix of external views based on different data models. It can include virtual tables that are computed with generic data to enhance the performance.
