    Smile Unanswered: Erd's and dfd's

    I am creating something in Visual Basic that will let the attendence information about a student to be stored in the database. The data will then be distributed into a database.

    The pictures below show the ERD and DFD that i created.

    The only reason I am creating a dfd and erd is for a college project.. I am really implementing this software though into the college

    Is the ERD constructed properly? Are the relationships and primary/foreign keys correct...?...

    And for the DFD I would like to know if the processes and the data flow terms are correct.

    Thank you in advance, I really appreciate any of the suggestions and help...
