Introduction to Apache Sling
Apache Sing is a Content-centric that means that when processing a request, it first finds the content then based on the content and request data determines how to render it.
Sling framework uses a JCR based repository as its data storage. In AEM all its data including the content, application binaries and configurations are all stored in the JCR repository.
When processing a web request Apache Sling resolves the request URL, analyze the content at the resolved paths and determines which script in the repository should be executed for rendering content view.
In addition, a part of that framework provides a very powerful functionality for component and dialogs inheritance.
