Is a database design based on Data Flow Diagram? Like, the number of datastores should be the same as the number of tables in the database?
i think database design based on Data Flow Diagram because Data flow diagrams are used to describe how the system transforms information.
Since the DB Design is based on DFD, then it is true that the ER is based on DFD because the DB design is dependent on ER.
i think it is more precise to say that DB Design is actually based from ER, but the number of DB that you are going to use/create must match with the number of DB indicated in your DFD .. this is as far as i can remember
azareth is right DB is actually based from Entity relationship diagram
