1. What Problem We Ran Into If the features you implement are simple and both development and maintenance are easy, there would be no research into design patterns, frameworks, and related topics.

It was initially used by its developers to manage news-content-focused websites, was open-sourced under the BSD license in July 2005, and formally established its foundation on June 17, 2008.

Its purpose is to solve the information silo problem caused by different IT resources within an enterprise being unable to interconnect.
