Process



1. Review all documentation so far prepared
2. Review web pages about DFDs, Data models, and costs....
3. Correct any marked defects.
4. Describe the required data base.
5. Validate your DFD against your data base. First every data store in the DFD should also be an entity in your ERD. You maqy need to change the names of data stores. Then check that every process in your DFD can get the data it needs from entities and relations in your ERD. Also that it can create, update, and delete the data it needs to change.
6. Revise data base and or DFD.
7. Resubmit a copy of the whole revised package.



Note: If a document is not changed, still hand it in for grading.
