A database management system (DBMS) is a software package designed to store, retrieve, query, and manage data. User interfaces (UIs) allow data to be created, read, updated, and deleted by authorized entities.

Database management systems are important because they provide programmers, database administrators, and end users with a centralized view of data and free applications and end users from having to understand where data is physically located. APIs (application program interfaces) handle requests and responses for specific types of data over the internet.

Relational and non-relational DBMS components delivered over the internet may be referred to as DBaaS (database as a service) in marketing materials. According to the research firm Gartner, database management systems designed to support distributed data in the cloud currently account for half of the total DBMS market.
