An embedded database system is a database management system (DBMS) which is tightly integrated with an application software that requires access to stored data, such that the database system is "hidden" from the application’s end-user and requires little or no ongoing maintenance. It is actually a broad technology category that includes * database systems with differing application programming interfaces (SQL as well as proprietary, native APIs), * database architectures (client-server and in-process), * storage modes (on-disk, in-memory, and combined), * database models (relational, object-oriented, entity–attribute–value model, network/CODASYL), and * target markets. The term ''embedded database'' can be confusing because only a small subset of embedded database products are used in real-time embedded systems such as telecommunications switches and consumer electronics devices.〔Graves, Steve.
