Database management is a method of managing the information that supports a company’s business operations. It involves storing data, disseminating it to users and applications and editing it as required and monitoring changes to data and stopping data corruption due unexpected failure. It is a part of a company’s informational infrastructure which aids in decision making and growth of the company as well as compliance with laws like the GDPR and the California Consumer Privacy Act.

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 data to be stored and retrieved for a variety of reasons.

A database is a set of tables that organizes data according to an established pattern, such as one-to many relationships. It uses primary key to identify records and allows cross-references among tables. Each table has a set of fields called attributes that contain information about data entities. Relational models, created by E. F. “TedCodd Codd in the 1970s at IBM as a database, are the most widely used type of database currently. The design is based on normalizing the data, making it easier to use. It is also easier to update data because it doesn’t require the modification of several databases.

Most DBMSs can accommodate multiple types of databases through different levels of internal and external organization. The internal level addresses costs, scalability, and other operational concerns including the layout of the physical storage. The external level is the representation of the database on user interfaces and applications. It could comprise a combination of various external views (based on different data models) and can also include virtual tables which are generated using generic data to improve performance.
