Using SQLite

SQLite Products

The SQLite project consists of four major products:

SQLite core

The SQLite core contains the actual database engine and public API. The core can be built into a static or dynamic library, or it can be built in directly to an application.

sqlite3 command-line tool

The sqlite3 application is a command-line tool that is built on top of the SQLite core. It allows a developer to issue interactive SQL commands to the SQLite core. It is extremely useful for developing and debugging queries.

Tcl extension

SQLite has a strong history with the Tcl language. This library is essentially a copy of the SQLite core with the Tcl bindings tacked on. When compiled into a library, this code exposes the SQLite interfaces to the Tcl language through the Tcl Extension Architecture (TEA). Outside of the native C API, these Tcl bindings are the only official programming interface supported directly by the SQLite team.

SQLite analyzer tool

The SQLite analyzer is used to analyze database files. It displays statistics about the database file size, fragmentation, available free space, and other data points. It is most useful for debugging performance issues related to the physical layout of the database file. It can also be used to determine if it is appropriate to VACUUM (repack and defragment) the database or not. The SQLite website provides precompiled sqlite3_analyzer executables for most desktop platforms. The source for the analyzer is only available through the development source distribution. ...
