This is a project that entails building a Knowledge Base System (KBS) for a fictitious stock broker firm. Our team is responsible for handling the Work Schedule and Buy & Sell function of this KBS. I need a data flow diagram built in Project or Excel that provides the process logic of the Buy & Sell portion of the system. The diagram should represent at least a level 1 diagram. Attached is a break down of the Buy & Sell portion of the KBS. I need this by Friday morning 06/09.
