Embedded Databases
Embedded databases are lightweight database management systems that run directly within an application's process, without requiring a separate server installation. They store data locally on the device or system where the application is deployed, providing fast, self-contained data persistence. 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 need local data storage without the overhead of a full database server, such as mobile apps, desktop tools, or IoT devices with limited resources. They are ideal for scenarios requiring portability, simplicity, and low latency, like caching, configuration storage, or offline data access in single-user or small-scale environments.
