Lecture Systems Analysis and Design in a Changing World (3rd Edition) - Chapter 10: The traditional approach to design

Lecture Systems Analysis and Design in a Changing World - Chapter 10 include objectives: Develop a system flowchart, develop a structure chart using transaction analysis and transform analysis, write pseudocode for structured modules. | Chapter 10: The Traditional Approach to Design Systems Analysis and Design in a Changing World, 3rd Edition Learning Objectives Develop a system flowchart Develop a structure chart using transaction analysis and transform analysis Write pseudocode for structured modules Overview Traditional approach to designing software Overview of structured models, model development process, related terminology How data flow diagrams are annotated with automation boundary information How analysis phase models are transformed into design models using system flowcharts, structure charts, and module pseudocode Integration into other design phase activities Applying approach to a three-layer architecture The Structured Approach to Designing the Application Architecture Application software programs Designed in conjunction with database and user interface Hierarchy of modules Design internal logic of individual modules Top-down approach DFDs with automation boundaries System flowcharts, structure charts, pseudocode Structured Design Models The Automation System Boundary Partitions data flow diagram processes into manual processes and automated systems Processes can be inside or outside boundary Data flows can be inside and outside of boundary Data flows that cross system boundary represent inputs and outputs of system Data flows that cross boundaries between programs represent program-to-program communication DFD with Automation System Boundary The System Flowchart Representation of various computer programs, files, databases, and associated manual processes that make up complete system Frequently constructed during analysis activities Graphically describes organization of subsystems into automated and manual components Can show type of transaction processing system Batch Real time Common System Flowchart Symbols Sample System Flowchart for Payroll System System Flowchart for RMO The Structure Chart Describes functions and subfunctions of . | Chapter 10: The Traditional Approach to Design Systems Analysis and Design in a Changing World, 3rd Edition Learning Objectives Develop a system flowchart Develop a structure chart using transaction analysis and transform analysis Write pseudocode for structured modules Overview Traditional approach to designing software Overview of structured models, model development process, related terminology How data flow diagrams are annotated with automation boundary information How analysis phase models are transformed into design models using system flowcharts, structure charts, and module pseudocode Integration into other design phase activities Applying approach to a three-layer architecture The Structured Approach to Designing the Application Architecture Application software programs Designed in conjunction with database and user interface Hierarchy of modules Design internal logic of individual modules Top-down approach DFDs with automation boundaries System flowcharts, .
