osCommerce: Detailed Technical Description
📅 Release Date
osCommerce (Open Source Commerce) was launched in March 2000 by Harald Ponce de Leon. It is one of the very first open source e-commerce solutions in web history. Version 2.2 (MS2) long served as the benchmark release, version 2.3 was published in 2010, and version 4.x (Community Edition) introduced a modern redesign.
📝 License
osCommerce is an open source software distributed under the GNU General Public License (GPL v2). It is entirely free in its Community Edition.
💻 Programming Language
osCommerce is developed in PHP. It relies on a procedural architecture for its legacy versions (2.x), then adopts object-oriented approaches in more recent releases. The front-end uses HTML, CSS, and JavaScript.
🏛️ Architecture
- • Partial MVC architecture with separation between business logic (PHP), data (MySQL), and presentation (HTML/CSS templates).
- • Front-office / back-office structure: customer-facing catalogue on one side, secured administration interface on the other (the
admin/directory). - • Module system (contributions) to extend functionality without modifying the CMS core.
- • Template system (STS — Simple Template System) for full customisation of the store's appearance.
- • Compatible with all web servers supporting PHP + MySQL (Apache, Nginx, IIS).
📂 Database
osCommerce relies exclusively on MySQL (or MariaDB) as its database management system. The database stores:
- • The product catalogue (categories, products, manufacturers, attributes).
- • Orders, customers, billing and shipping addresses.
- • Sessions, shopping carts, customer reviews, taxes, and geographic zones.
- • Store configuration settings and localisation data.
The minimum required version is MySQL 3.23, but recent versions recommend MySQL 5.x or MariaDB 10.x.
