Database management is a system for managing information that supports an organization’s business operations. It involves storing and distributing data it to applications and users and editing it when needed as well as monitoring changes in data and protecting against data corruption due to unexpected failure. It is part of the overall infrastructure of a business which supports decision-making in corporate growth, as well as compliance with laws such as the GDPR and California Consumer Privacy Act.

The first database systems were created in the 1960s by Charles Bachman, IBM and others. They evolved into information management systems (IMS), which allowed huge amounts of data to be stored and retrieved for a range of purposes. From calculating inventory, to supporting complex financial accounting functions as well as human resource functions.

A database is a set of tables which organize data according to a certain scheme, like one-to many relationships. It uses primary keys to identify records and permit cross-references between tables. Each table has a set of fields, also known as attributes, that contain information about the data entities. Relational models, invented by E. F. “Ted” Codd in the 1970s at IBM and IBM, are among the most well-known database type currently. This model is based upon normalizing the data, making it more easy to use. It is also easier to update data since it does not require changing various databases.

The majority of DBMSs are able to support multiple database types by providing different levels of internal and external organization. The internal level addresses cost, scalability and other operational issues like the layout of the database’s physical storage. The external level is the representation of the database in user interfaces and applications. It can include a mixture of different external views that are based on different data models. It could include virtual tables that are computed using generic data in order to improve the performance.
