TAILIEUCHUNG - Lecture Systems Analysis and Design in a Changing World (3rd Edition) - Chapter 9: Moving to design

Learning objectives for this chapter: Discuss the issues related to managing and coordinating the design phase of the SDLC, explain the major components and levels of design, describe each design phase activity,. | Chapter 9: Moving to Design Systems Analysis and Design in a Changing World, 3rd Edition Learning Objectives Discuss the issues related to managing and coordinating the design phase of the SDLC Explain the major components and levels of design Describe each design phase activity Describe common deployment environments and matching application architectures Develop a simple network diagram and estimate communication capacity requirements Overview This chapter: Completes the transition from analysis to design Discusses issues related to design of new system Describes all design phase activities Describes network and architecture design Analysis focuses on what system should do – business requirements Design is oriented toward how system will be built – defining structural components Understanding the Elements of Design Design is process of describing, organizing, and structuring system components at architectural design level and detailed design level Focused on construction Like developing blueprints Three questions: What components require systems design? What are inputs to and outputs of design process? How is systems design done? Components Requiring Systems Design Analysis Objectives to Design Objectives Moving from Analysis to Design Design: Converts functional models from analysis into models that represent the solution Focused on technical issues Requires less user involvement than analysis Design may use structured or OO approaches Database can be relational, OO or hybrid User interface issues Traditional Structured and Object-Oriented Models SDLC Phases with Design Phase Activities Design Phase Activities and Key Questions Design and Integrate the Network Network specialists establish network based on strategic plan Project team typically integrates system into existing network Technical requirements have to do with communication via networks Technical issues handled by network specialists: Reliability, security, .
