tailieunhanh - Lecture Introduction to systems analysis and design: Chapter 17 - Whitten, Bentley

Chapter 17 - Object-oriented design and modeling using the UML. This is the second of two chapters on object-oriented tools and techniques for systems development. This chapter focuses specifically on tools and techniques that are used during systems design. | Chapter 17 Object-Oriented Design and Modeling Using the UML This repository of slides is intended to support the named chapter. The slide repository should be used as follows: Copy the file to a unique name for your course and unit. Edit the file by deleting those slides you don’t want to cover, editing other slides as appropriate to your course, and adding slides as desired. Print the slides to produce transparency masters or print directly to film or present the slides using a computer image projector. Each slide includes instructor notes. To view those notes in PowerPoint, click-left on the View Menu; then click left on Notes View sub-menu. You may need to scroll down to see the instructor notes. Teaching Notes This slide shows the how this chapter's content fits with the building blocks framework used throughout the textbook. The emphasis of this chapter is with the physical design phase, focusing on COMMUNICATION. It involves system designers and systems analysts.

Chapter 18 – Object-Oriented Design and Modeling Using the UML Objectives Understand entity, interface, control, persistence, and system classes. Understand the concepts of dependency and navigability. Define visibility and explain its three levels. Understand the concept object responsibility and how it is related to message sending between object types. Describe the activities involved in object-oriented design. Differentiate between a design use-case narrative and an analysis use-case narrative. Describe CRC card modeling. Model class interactions with sequence diagrams. Construct a class diagram that reflects design specifics. Model object states with state machine diagrams. No additional notes. Chapter 18 – Object-Oriented Design and Modeling Using the UML Object-Oriented Design Object-oriented design (OOD) – an approach used to specify the software solution in terms of collaborating objects, their attributes, and their methods.
