Zend Framework is an open-source enterprise ready web application framework. Built on PHP 5 code, Zend offers an loosely coupled, event-driven MVC (Model-View-Controller) architecture with minimal dependencies among components via dependency injection. It comes with EventManager for coding event-driven systems, a view layer that analyzes requests from HTML, JSON, and others and then generates an appropriate response, and an extensible module management system. By default Zend offers support of multiple database frameworks, including MySQL, Microsoft SQL Server, PostgreSQL, Oracle, IBM DB2, and MariaDB, among others. Zend’s technology partners include IBM, Google, and Adobe Systems.
