# Portal Key Concepts and Architecture

The following figure illustrates the flexibility and extensibility of the WebLogic Portal architecture. Whether you are building portal resources and templates in WebLogic Workshop or creating and administering portals with the WebLogic Administration Portal, you can work with individual components that are then unified by the portal framework.

In the figure, (1...n) means one or more, and (0...n) means zero or more. For example, a portal can contain one or more desktops. For resources that occur only once, like Look and Feel and Shell, you can still develop multiple versions even though only one at a time is allowed.

For descriptions of the portal components, see What is a Portal?.
