interfaces

Should an interface only be used to specify certain behavior? Would it be wrong to use interface to group logically related data?

To me it looks like we should not use interface to group logically related data as structure seems a better fit. A class may be used but class name should indicate something like DTO so that user gets the impression that class does not have any behavior.

Please let me know if my assumption is correct.

Also, are there any exceptions where interface can be used to group logically related data?
