The workshop divides design into Preliminary Design, External Design and Internal Design. Preliminary Design accomplishes the transition from analy-sis and determines the technical architec-ture of the system. It also decides what processes and data will reside on which processors. External Design is design from the viewpoint of the user. It defines dialogue flow and provides screen and report design. Internal Design is design from the viewpoint of the builder. It op-timizes the data, structures the logic and defines interfaces.It uses the same case study as BAA. You complete the course with experi-ence in design.The workshop provides a full dis-cussion of logical data base design. You will learn how to apply safe and aggres-sive trade-offs for optimizing the data. Safe trade-offs optimize the data without compromising integrity and redundancy. Aggressive trade-offs optimize the data while providing some compromise of integrity or redundancy.
