Database management is a system for managing information that supports the business operations of an organization It involves storing and distributing data it to users and applications and editing it as required as well as monitoring changes in data and making sure that data integrity is not compromised due to unexpected failure. It is a part of the overall infrastructure of a business which supports decision-making as well as corporate growth and 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 the information management systems (IMS) that allowed the storage and retrieve huge amounts of data for a variety of uses, from calculating inventory to supporting complex financial accounting and human resources functions.

A database is a set of tables that are organized according to a certain schema, such as one-to many relationships. It utilizes primary keys to identify records and allows cross-references between tables. Each table contains a set of attributes, or fields, which provide information about data entities. The most well-known type of database currently is a relational model designed by E. F. “Ted” Codd at IBM in the 1970s. This design is based on normalizing data to make it more user-friendly. It is also simpler to update data since it doesn’t require changing several databases.

The majority of DBMSs are able to support various types of databases, by providing different levels of external and internal organization. The internal level deals with cost, scalability and other operational concerns including the design of the database’s physical storage. The external level is how the database appears in user interfaces and other applications. It can include a mixture of various external views based on different data models. It could include virtual tables that are calculated using generic data to enhance the performance.
