Joining Fact tables

Our college is making a data warehouse and we were thinking of having a fact table that is kind of an overview of for a student which links to a transaction fact table to give a more detailed view of each transaction code. So, I could see that they have an account balance in the student fact table along with pell grant amount for a given term, but we were thinking of adding a table to link to that to see the details. Is this advisable?

Thanks!

In dimensional terms, you have two fact tables that share student as one of the dimensions. In your use case, drilling into details involves a separate query against the detail fact using known, common dimensional values (i.e. filter on student, semester). You don't need to 'join/link the fact tables'.
