CQ5 and Sling provide an overview of content management systems and frameworks. CQ5 is a content management system built on Apache Sling, which is an applications framework for JCR content repositories based on OSGi. Sling allows for dynamic modules and services and fosters modular code. Together, CQ5 and Sling provide a flexible and powerful way to manage content on a website through a content-centric approach where everything is treated as content.
