SQLite, a lightweight database, is a relational database management system that complies with ACID. It is contained in a relatively small C library. It is a public domain project established by D. Richard Hipp. Its design goal is embedded, and it has been used in many embedded products. It occupies very low resources. In embedded devices, only a few hundred K of memory may be enough. It can support mainstream operating systems such as Windows/Linux/Unix, and can be combined with many programming languages, such as Tcl, C#, PHP, Java, etc., as well as ODBC interfaces. It is also compared with the two open source Mysql and PostgreSQL In terms of world-famous database management systems, its processing speed is faster than them.
