I’m trying to find a module(or module suite) that will allow for cross referencing  or cross linking two district content types (e.g. people  and responsibilities) in a many to many relationship. I’ve looked around and I’m not finding anything that hits the target right on. I’m trying to avoid building this from the ground up. Here's a description of what I'm looking for below, any recommendations are welcome. I was also wondering if I could accomplish this with DNN's Form and List module?

Data structure: I have content A and content B, I need to associate these two by way of a cross-join table to ensure a many to many relationship they have.

Back end: module(or module suite) that would interact with the data to create, read, update, & delete and of course enforce the data structure mentioned above.

Front end:  need to have the ability to display the cross linked content; display content A (HTML module or natively in this ? module) and a listing of the associated content B and vice versa.

Thank you for any direction or recommendations in advance.
