Hi tribilin80,
http://en.wikipedia.org/wiki/Moodle
According to Wikipedia, The Moodle system is defined as, "a free and open source e-learning software platform, also known as a Course Management System, Learning Management System, or Virtual Learning Environment. It has a significant user base with 49,256 registered sites with 28,177,443 users in 2,571,855 courses (as of February, 2009)[1].
Moodle is designed to help educators create online courses with
opportunities for rich interaction. Its open source license and modular
design means that people can develop additional functionality.
Development is undertaken by a globally diffused network of commercial
and non-commercial users, streamlined by the Moodle company based in Perth, Western Australia.
Moodle features
Moodle has many features expected from an e-learning platform, plus
some original innovations (for example its filtering system).
Moodle is modular in construction and can readily be extended by
creating plugins for specific new functionality. Moodle's
infrastructure supports many types of plugins:
- Activities
- Resource types
- Question types
- Data field types (for the database activity)
- Graphical themes
- Authentication methods
- Enrollment methods
- Content Filters
Many third-party Moodle plugins are freely available making use of this infrastructure.[2]
PHP can
be used to author and contribute new modules. Moodle's development has
been assisted by the work of open source programmers.[3] This has contributed towards its rapid development and rapid bug fixes.
Specifications:
Moodle runs without modification on Unix, Linux, FreeBSD, Windows, Mac OS X, NetWare and any other systems that support PHP and a database, including most webhost providers.
Data is stored in a single database: Moodle version 1.6 could use MySQL or PostgreSQL.
Version 1.7, released November 2006, makes full use of database
abstraction so that installers can choose from one of many types of
database servers (Oracle and Microsoft SQL Server are two specific target DBMSes). The current version of Moodle (1.9), was released in March 2008."
I hope this helps,
Jim
