The embedded database is a "lightweight" block data management tool. Embedded databases are lightweight, self-contained libraries with no server components, no management required, a small code size, and limited resource requirements. At runtime, they require less memory; they are written in compact code, making them faster and more effective for embedded devices.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The name of the embedded database comes from its unique mode of operation. This database is embedded into the application process, eliminating the overhead associated with client-server configuration.
Embedded databases are actually lightweight, and at runtime, they require less memory. They are written using streamlined code, which is faster and more effective for embedded devices.
Embedded run mode allows an embedded database to easily manage application data through SQL rather than relying on raw text files. The embedded database also offers a zero-configuration run mode, which allows one to be enabled and a snapshot to be run.
Embedded database is an important part of embedded systems and has become an indispensable and effective means for the development and management of more and more personalized applications.
Embedded databases are widely used, such as in consumer electronics, mobile computing devices, enterprise real-time management applications, network storage and management, and various special equipment. This market is currently experiencing rapid growth. To give a simple example, mobile phones were originally only used to make calls and send text messages. Now mobile phones have added many new functions, such as MMS, music, photography, video, etc. With more application functions, the system becomes more complex.
