Formulating DFD's and ERD's in the design phase of a new system
Posted on 2004-10-07
I am currently in a group who is working on a new automated system for a business. This system will be used for employee shift changes and keep track of these shift changes. We have formulated the Context Diagram which contains an Employee and Manager entity, and breaks off into one process which is the Shift Change System. From there we go to the Level 1 Diagram, which again contains an Employee and a Manager entity. The processes now, in the level one diagram are stumping all of us. We are confused as to where to go from here, and what should be put in the processes, and what data flow information should go where, and then after the DFD's, how exactly are the ERD's going to be drawn?...Thanks to any and all for any help you can provide. I really appreciate it.
