Sitefinity features two types of publishing points:

• Persistent publishing point - it stores the data in the database

• Pass through publishing point - it pushes the data that it receives immediately

There are two types of pipes:

• Push pipe - it passes the data to the publishing point or destination when it receives it

• Pull pipe - it pushes the data on demand, when it is requested

Push Pipe - Persistent Point - Pull Pipe

You use this scenario when you import data that you need to store. You collect data that you cannot guarantee exists upon request from external source.

For example: RSS feed

Push Pipe - Pass through Point - Push Pipe

You use this scenario when you need to flush data from Sitefinity into external source like tweeter, but you do not need to store the data.

Pull Pipe - Pass through Point - Pull Pipe

You use this scenario when you have the data and do not need to duplicate it in the publishing point.

For example: RSS feed in Sitefinity

You can also have a combination between Pull and Push pipes on the both sides of the publishing point.
