Embedded Database
An embedded database is a database management system (DBMS) that is tightly integrated with an application, running within the same process and storing data locally rather than on a separate server. It is designed for lightweight, self-contained applications where simplicity, low latency, and minimal setup are priorities. Common examples include SQLite, H2, and LevelDB, which are often used in mobile apps, desktop software, IoT devices, and embedded systems.
Developers should use embedded databases when building applications that require local data storage without the overhead of a separate database server, such as mobile apps (e.g., Android with SQLite), desktop applications, or embedded systems in IoT devices. They are ideal for scenarios where data needs to be accessed quickly with minimal configuration, in single-user or low-concurrency environments, or for prototyping and testing where simplicity is key. However, they are less suitable for high-concurrency, distributed, or large-scale multi-user applications compared to client-server databases.
