Database management is the system to manage information that is essential to the company’s business operations.

It is an integral part of the entire informational infrastructure of a company that assists in decision making in corporate growth, as well as compliance with laws such as the GDPR and California Consumer Privacy Act.
In the 1960s, Charles Bachman and IBM among others developed the first database systems. They evolved into information management systems (IMS) that allowed the storage and retrieve large amounts data for a broad range of applications, from the calculation of inventory to supporting complicated financial accounting and human resources functions.
A database consists of a set of tables that are organized in accordance with a specific arrangement, like one-to-many relationships. It utilizes primary keys to identify records and permit cross-references between tables. Each table contains a number of fields, also known as attributes, that represent facts about the data entities. Relational models, developed by E. F. “TedCodd Codd in the 1970s at IBM and IBM, are the most well-known database type today. This design is based upon normalizing data to make it more user-friendly. It is also easier to update data because it does not require the changing of certain sections of the database.
The majority of DBMSs support a variety of databases and offer different internal and external levels of organization. The internal level addresses cost, scalability and other operational concerns like the layout of the database’s physical storage. The external level is the representation of the database on user interfaces and applications. It may include a mix of different external views based on different models of data and may also include virtual tables that are calculated using generic data to improve the performance.
