Database management is the process for managing information that supports the company’s business operations.

It is an integral part of the informational infrastructure of a business that aids in decision-making, corporate growth, and compliance with laws like the GDPR and California Consumer Privacy Act.
The first database systems were developed in the 1960s by Charles Bachman, IBM and others. They developed into information management systems (IMS) that allowed for the storage and retrieve massive amounts of data for a variety of purposes, ranging from calculating inventory to supporting complex human resources and financial accounting functions.
A database is a set of tables that organize data according to a certain arrangement, like one-to-many relationships. It utilizes primary keys to identify records and allow cross-references between tables. Each table has a set of fields, known as attributes, which provide information about the data entities. The most popular 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 the data, making it more easy to use. It is also simpler to update data because it does not require changing several databases.
Most DBMSs are able to support different types of databases and offer different internal and external levels of organization. The internal level deals with costs, scalability, and other operational issues, such as the design 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 external views based on different models of data and can include virtual tables that are computed using generic data in order to improve the performance.
