1. CPSC 871 John D. McGregor M33S1 Foundations of Software Engineering

2. Abstraction Omit detail Focus on essentials/properties Types – Specification – Implementation dependencies

3. Encapsulation

4. Information hiding Eliminate dependencies

5. Modularization Coupling/cohesion

6. Generalization/Specialization Inheritance Refinement extension

7. Hierarchy Composition Generalization Priority Incremental

8. Paradigms Functional/procedural Object-oriented Service-oriented

9. Processes Waterfall Iterative-incremental Spiral Driven – Model – Test Process modeling – Epf Metrics

10. Algorithms/structures Languages – General purpose – Domain specific Complexity theory – Runtime - cs – Incidental Bad organization – Inherent Algorithmic

11. Analysis Operational context Economic perspective Requirements – Elicitation Sources interviews – Analysis Hierarchical Interactions Functional/non-functional

12. Architecture/Design Specifications Nominal/exceptional/error flows Constraints Trade-offs Design Patterns

13. Construction Traceability Standard languages Metrics Language idioms

14. Validation & verification Validation – Compare to human expectations Verification – Compare to some independent standard – oracle Operates in parallel to the development process

15. Tools Operating system Programming – compilers/interpreters/translators – debuggers Translator – Because it is the human that is the weakest link – Object-oriented, data driven, procedural, functional are all reducible – The languages are there to help us
