How to create "many-to-many" relationship

Hey,

Can anyone give me an explanation on how to create "many-to-many" relationship - Between "Contacts" and "Products". So that the final result would be as follows:
1. Many contacts can have many products
2. The same product can be related to many products

Thanks

I believe this article is out of date. Since the custom  field Master-Detail Relationship does not exist any moreUser-added image

Hi, 

You can use a junction object to connect the two objects you want to relate to each other.
A junction object is a custom object with two master-detail relationships. Using a custom junction object, you can model a “many-to-many” relationship between two objects. For example, you create a custom object called “Bug” that relates to the standard case object such that a bug could be related to multiple cases and a case could also be related to multiple bugs.

Here is some useful links that will help in setting up your requirement:

Hope it helps.
Thanks,
