MET CS 669 Database Design and Implementation for Business Term Project Iteration 2: Initial Design Now that you have decided on a direction for your Term Project, you can now start with an initial design. Structural business rules and a conceptual entity-relationship diagram (ERD) are a useful tool to frame your initial design. You will be providing both in this Term Project iteration. Let us review the basics of both of these items. The structural business rules will indicate the entities, relationships, optionalities, and pluralities of your Term Project design. For example, “A person may own many cars; a car is owned by one person” is an example of a structural business rule. A conceptual ERD is independent of the relational model, and therefore does not contain primary and foreign key constraints.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
