In Zope, a web application is built out of objects. These objects perform myriad tasks but are usually one of the following types:
Content objects, which hold types of data such as documents, images, and other retrievable files
Presentation objects, often called templates
Logic objects, which enable you to perform tasks with your object using a language such as Python
The concept of object orientation is often a difficult one to grasp for the uninitiated, but it's an important concept to understand to fully appreciate the powers of Zope. Everything in Zope is an object: folders, forms that you create, an instance of a file, and so on. Next you'll read perhaps the world's shortest primer on objects.
