Database management is a system to manage information that is essential to the organization's business processes. It involves storing and distributing data it to users and applications and editing it as required and monitoring changes to the data and stopping data corruption due unexpected failure. It is an element of a company's total informational infrastructure that supports decision-making and growth for the business as well as compliance with laws such as materio.cm the GDPR and the California Consumer Privacy Act.

In the 1960s, Charles Bachman and IBM among others developed the first database systems. They developed into information management systems (IMS) which enabled the storage and retrieve massive amounts of information for a range of applications, from the calculation of inventory to supporting complex financial accounting and human resources functions.

A database is tables that store data according to a certain pattern, for example, one-to-many relationships. It makes use of primary keys to identify records and allows cross-references between tables. Each table has a collection of fields called attributes that contain information about data entities. Relational models, developed by E. F. “TedCodd Codd in the 1970s at IBM and IBM, are the most well-known database type currently. The design is based on normalizing the data, making it simpler to use. It also makes it easier to update data without the necessity of changing different sections of the database.

Most DBMSs can support multiple types of databases through different levels of external and internal organization. The internal level focuses on cost, scalability and other operational concerns such as the layout of the database's physical storage. The external level is the representation of the database on user interfaces and applications. It could include a mix of different external views (based on the different data models) and may also include virtual tables that are constructed using generic data to improve performance.
