SQLite
From MediaWiki.org
As of 1.13 SQLite support is part of the main codebase, however there are some notes below on installing the SQLite library into your PHP environment. The development notes and future plans are at OrganicDesign:MediaWikiLite.
[edit] About SQLite
The following description is from Wikipedia:SQLite. Unlike client-server database management systems, the SQLite engine is not a standalone process with which the program communicates. Instead, the SQLite library is linked in and thus becomes an integral part of the program. The program uses SQLite's functionality through simple function calls, which reduces latency in database access as function calls are more efficient than inter-process communication. The entire database (definitions, tables, indices, and the data itself) is stored as a single cross-platform file on a host machine. This simple design is achieved by locking the entire database file at the beginning of a transaction.
SQLite was created by D. Richard Hipp, who sells training, direct technical support contracts and add-ons such as compression and encryption. The source code for SQLite is in the public domain.
[edit] SQLite Installation
It's important to have this working with SQLite3 rather than 2 because version 3 supports more similar syntax for some SQL such as table creation than version 2. Aside from that, version 3 uses more compact files and executes more efficiently. SQLite3 works via PHP's PDO functions.
- To install SQLite3 on a Debian based system, use apt-get install php5-sqlite3.
- Check your phpinfo() to see if pdo_sqlite is listed, if not, try adding extension=php_pdo_sqlite.so into the dynamic extensions section of your php.ini
- Installer script needs to be patched to allow SQLite to work for a wiki installation since extensions are added from LocalSettings.php
