Schema Design / Tamino JOINS

Are there any examples showing how to join collections?
Problem:
For example i have a database with three collections.
1. Classes of Problems
2. Problems
3. Results

Now i have the possibility to create only ONE Schema. I think if i have two Problems with the same result then the result data is stored for MULTIPLE times?!

So i would like to create three seperate Collections which are linked. In Tamino i think it

Hello Michael,
have a look at the documenation: There is a chapter “Representing Joins” under the topic Tamino Schema Definition. There you’ll hopefully find those informations/examples.
