CSC426 - Software Engineering Lecture Note Cont'd

  1. 1. CSC426: SOFTWARE ENGINEERING AJAYI, O. O. (Lecturer, CSC Dept., AAU Akungba-Akoko, Ondo State, Nigeria) 07056433798 / 08137044500 / 08113699553 1
  2. 2. PART 1 CONT’D i. Time to Market ii. Object Oriented App iii. User Desktop Computing iv. GUI v. Networking vi. Open Source vii.Economics viii.Newer and Faster Development Models The CHANGE in SOFTWARE ENGINEERING 2
  3. 3. PART 1 CONT’D i. Time to Market: This described the time taken to conceive a project idea, transform the idea to a systemic form and deliver the project. This change is enhanced with modern techniques of reviewing and testing software. Also, the advent of memory technology has jettison the need for rigorous and time-wasting code optimizing process. The CHANGE in SOFTWARE ENGINEERING 3
  4. 4. PART 1 CONT’D i. Discuss strategies/ways by which your application can beat other competitors to the market. Under Topic Exercise (UTE) I 4
  5. 5. PART 1 CONT’D ii. Object Oriented App: With the birth of object-oriented software, developers now have access to rich library and reusable artifacts/components, which in a great measure reduces time taken for their app to land in market. The CHANGE in SOFTWARE ENGINEERING 5
  6. 6. PART 1 CONT’D i. Pick any choice object-oriented language and discuss its features as well as its shortcoming as a language. ii. As notable in the previous slide, OO contributes largely in terms of library repository. Demonstrate the use of library resources in the OO language selected in (i). UTE II 6
  7. 7. PART 1 CONT’D iii. User Desktop Computing With the proliferations of different desktop applications/software, software developers can now concentrate on building sophisticated and more complex applications as users can on their own develop simple, common and domestic applications with the various freely available desktop apps. The CHANGE in SOFTWARE ENGINEERING 7
  8. 8. PART 1 CONT’D i. Decide on any desktop app and develop a simple but sensible app. ii. Document every step of the app’s design and execution/implementation flow to prove originality of authorship UTE III 8
  9. 9. PART 1 CONT’D iv. GUI Gone are those days when DOS-based apps when reigning. Now, the table has turned, windows-based apps are on the streets. This has greatly enhanced the embracement of software and has resulted into higher yields for practitioners. The CHANGE in SOFTWARE ENGINEERING 9
  10. 10. PART 1 CONT’D i. Many event-driven and graphical programming languages exist. Demonstrate the advantage of creating a user-friendly and easy navigation in app, using such language. UTE IV 10
  11. 11. PART 1 CONT’D v. Networking With the advent of internet and rapid increase in the level of networking across organizations, users have no ‘headache’ of feedbacking the developer on every simple ‘problem/challenge’ encountered as enquiries can be made online to trace the problem and access info for probable solution. The CHANGE in SOFTWARE ENGINEERING 11
  12. 12. PART 1 CONT’D i. Develop a simple ‘Online Troubleshooting App’ for feedbacking clients on program error such as ‘library not found….’. UTE V 12
  13. 13. PART 1 CONT’D vi. Open Source Aside offering resources in terms of library, solution etc., open source platform also affords enhancement to solution by giving rooms for other authors/developers to contribute to the efficiency and robustness of apps. The CHANGE in SOFTWARE ENGINEERING 13
  14. 14. PART 1 CONT’D i. Access any open source platform, modify any available educational software to suit your taste. ii. Report and document the accessed platform as well as the functional app, library or codes accessed, as the case may be. UTE VI 14
  15. 15. PART 1 CONT’D vii. Economics A technology-driven society enhances the acceptance of software application. The witnessed rampant usage of mobile technology has also led to high rate of mobile app development. The CHANGE in SOFTWARE ENGINEERING 15
  16. 16. PART 1 CONT’D i. Bring up a short term paper titled: ‘Analyzing the impact of technology on software evolution and embracement’. ii. Develop a mobile demo app, capable of catching the attention of a novice or new comers to this field of computing. UTE VII 16
  17. 17. PART 1 CONT’D viii. Newer and Faster Development Models No doubt, Water Fall Model presents lots of advantages over Evolutionary Model. Howbeit some of the major setbacks in the models include time to market and lack of adequate validation process. This has however given birth to new and faster software development model including modified waterfall model with appropriate validations. The CHANGE in SOFTWARE ENGINEERING 17
  18. 18. PART 1 CONT’D i. Criticize the Waterfall Model. UTE VIII 18
  19. 19. PART 1 CONT’D Time to Market Object Oriented App User Desktop Computing GUI Networking Open Source Newer and Faster Development Models Economics The CHANGE in SOFTWARE ENGINEERING CHANGE Figure 1: Change in S.E. 19
