Relational vs. dimensional data marts

Does a data warehouse design have to be relational vs. a dimensional design in a data mart?
You said "in a data mart". I don't know if you have a data warehouse to go along with that data mart or not.

The last layer in a data warehouse architecture should usually be dimensional because it more greatly facilitates end-user access with its built-in relationships. Some data marts are very specialized, however. Some may not be for true end-user ad-hoc query analysis and therefore the requirements may dictate a different, and sometimes a very particular type, of design. Some support packaged applications.

If you have a single data warehouse/mart only, then you will likely have both relational and dimensional structures in it because it is difficult to jump from many source environments directly to dimensional.
