SQLite for Linux file extensions

SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed SQL database engine in the world. The source code for SQLite is in the public domain.

SQLite Features:

• Transactions are atomic, consistent, isolated, and durable (ACID) even after system crashes and power failures.
• Zero-configuration - no setup or administration needed.
• Implements most of SQL92. (Features not supported)
• A complete database is stored in a single cross-platform disk file.
• Supports terabyte-sized databases and gigabyte-sized strings and blobs. (See limits.html.)
• Small code footprint: less than 300KiB fully configured or less than 180KiB with optional features omitted.
• Faster than popular client/server database engines for most common operations.
• Simple, easy to use API.
• Written in ANSI-C. TCL bindings included. Bindings for dozens of other languages available separately.
• Well-commented source code with 100% branch test coverage.
• Available as a single ANSI-C source-code file that you can easily drop into another project.
• Self-contained: no external dependencies.
• Cross-platform: Unix (Linux and Mac OS X), OS/2, and Windows (Win32 and WinCE) are supported out of the box. Easy to port to other systems.
• Sources are in the public domain. Use for any purpose.
• Comes with a standalone command-line interface (CLI) client that can be used to administer SQLite databases.
