Problem:
When and how to use Many to Many relationship

Solution:
Creating many to many relationships is depends on upon the structure of your data. How you setup your post types and taxonomies.

There are 2 ways to establish many to many relationship:
1) Creating Many to Many Relationships Using an Intermediary Object
2) Using WordPress taxonomy

I've described in detail with following reply:

Problem:
How can posts be connected in Toolset?

Solution:
1. You can create a parent/child relationship
Then, a Post in the Child Post type can be associated with one parent of another Post Type
And a parent, of a parent Post type, can have many children's in another post type

2. You can insert an Intermediary post Object (also a Post Type) which is a child of both above initial post Types.
This will allow you to have many to many relationships between 2 post types

3. You can use the WordPress native relationships if you enable Page Attributes for your Post Type.
Then, you can set a parent of the SAME post type to a given post in post type.
