Database management is the system for managing data that supports the company’s business operations. It involves storing data, distributing it to applications and users making edits as needed as well as monitoring changes in data and protecting against data corruption due to unexpected failure.

The first database systems were created in the 1960s by Charles Bachman, IBM and others. They developed into information management systems (IMS), which allowed large amounts of data to be stored and retrieved for a range of purposes.

A database is tables that store data according to a particular schema, such as one-to many relationships. It uses the primary key to identify records and allow cross-references between tables. afrogric.com Each table is comprised of a set of attributes or fields that represent facts about data entities. Relational models, which were developed by E. F. “Ted” Codd in the 1970s at IBM and IBM, are among the most widely used type of database currently. This design is based on normalizing data to make it more user-friendly. It also makes it easier to update data without the need to modify various databases.
Most DBMSs support multiple types of databases and offer different internal and external levels of organization. The internal level deals with cost, scalability, and other operational issues like the physical layout of the database. The external level determines how the database appears in user interfaces and other applications. It could include a mix of different external views based on different models of data and could include virtual tables that are calculated using generic data to improve the performance.
