- 3. PART 1 Amit Kundu 161-15-7149 Introduction
- 4. Computer-aided Software Engineering CASE • Automated software tools used by systems analysts to develop information systems • Used to support or automate activities throughout the systems development life cycle (SDLC) • Increase productivity • Improve overall quality of systems
- 6. • Reverse engineering • Reengineering Categories of CASE Products
- 7. PART 2 Khairul Alam Ovy 161-15-6979 The Use of CASE in Organizations
- 8. 1. Improve quality of systems developed. 2. Increase speed of development and design. 3. improve testing process through automated checking . 4. Improve quality and completeness of documentation.
- 9. 5. Improve project management. 6. Simply program maintenance . 7. Promote reusability. 8. Improve software portability.
- 10. • Majority of organizations adopt CASE to improve speed and quality of systems development projects. • Widespread deployment has been slower than expected. CASE and System Quality
- 11. Several factors that inhibit widespread deployment Cost Between $5,000 and $15,000 per year to provide CASE tools to one systems analyst Return on Investment Biggest benefits of CASE come in late stages of SDLC Productivity Bottlenecks Difficulty in providing tools for all staes of SDLC Cont..
- 12. Functionality is increasing. • Cost is decreasing. Reverse Engineering Tools Automated tools that read program source code as input and create graphical and textual representations of program design-level information. The Outlook for CASE
- 14. • Upper CASE • Lower CASE • Cross life-cycle CASE Components of CASE
- 15. Types of CASE tools Components of CASE • Diagramming tools • Computer display and report generators • Analysis tools • A central repository • Documentation generators • Code generators
- 16. CASE Diagramming Tools • Several types of diagrams : Data Flow Diagrams (DFD) Functional Hierarchy Diagrams Entity-Relationship Diagrams
- 17. CASE Form & Report Generator Tools • Two Purposes: 1) Create, modify and test prototypes of computer display forms and reports 2)Identify which data items to display or collect for each form or report
- 19. 4 Md. Shakil Mahmud 152-15-5573 Difference between CASE-Based Systems Development and Traditional Systems Development
- 20. Weaknesses of Traditional Systems Development No support for integration of documents Documentation after coding Out-of-date documentation
- 21. Traditional Systems Development vs CASE-Based Systems Development Emphasis Type Coding MaintainTaskDocumentation
