Dataflow Diagram Walkthrough

Date: 1/20/99

Presenter: Dr. Dalbey

Reviewers: CSc 205 students

Issues Raised:

1. Doesn't Reset Board need an input data flow, e.g. Player Request?
2. Shouldn't Update Board receive the board as an input dataflow from the Board data store?
3. Doesn't Is Valid Move need the Board in order to determine a move's validity?

Action Taken:

1. None. Player Request is a control flow not a data flow.
2. None. By convention, the data flow into the data store implies that Board was updated.
3. Added a data flow from board data store to the Is Valid Move process.
