2. jgs Previously … GoF Patterns
3. jgs 564 00010100 GUI Box Name1 Name2 class Name1 { } class Name2 { method(){ Name1 Cat } } class Cat extends Name1 { Car } class Car { } Cat 7. Allow Drag and Drop Car
4. jgs 564 00010100 § UML Class Diagram § Model-View-Controller § Observer § Singleton (Blackboard) § Decorator § Other: chain of responsibilities, strategy, bridge, § Source Code § JavaDoc (Classes and Methods)
5. jgs 564 00010100 Questions
6. jgs 564 00010100 It is This Time of the Semester When …
7. jgs 564 00010100 It is This Time of the Semester When … § Do NOT be a Grade Grubber § Grading is done by applying the same policies to all students as it is described in the syllabus. § It is unethical to bring to your instructor's attention the possible impact of your course grade on your plans, including graduation, scholarships, jobs, etc. Do not send requests to your instructor asking for a grade you did not earn with your work.
8. jgs Next Step Software Architecture
9. jgs 564 00010100 Timeline 1989 Beck OO Thinking Architecture 1993 Gamma et al. GoF Patterns 1994 Garlan
10. jgs 564 00010100 Definition § Software design It is responsible for the code level design: what each class is doing, its relationships, and scope. § Software architecture It is responsible for the skeleton and the high-level organization of a software. It identifies the main structural modules (or components) in a system and the relationships between them.
11. jgs 564 00010100 Architecture Goals § Define separate branches for each major function § Coordinate communication between modules § Limit propagation of side effects § Facilitate extensibility, modifiability and reuse
12. jgs 564 00010100 Architectural Patterns 1. Model-View-Controller (MVC) 2. Layered Architecture 3. Repository Architecture (Blackboard) 4. Client-Server architecture
13. jgs Architecture Patterns Model-View-Controller
14. jgs 564 00010100 Model-View-Controller
15. jgs 564 00010100 Implementation :: View
16. jgs 564 00010100 Implementation :: Controller
17. jgs Architecture Patterns Blackboard
18. jgs 564 00010100 Blackboard
19. jgs 564 00010100 Drafting an Implementation
20. jgs 564 00010100 What about Blackboard § Singleton (yes or not)? § Create Blackboard in main method (yes or not)? § Connection between Blackboard and Professor (association, aggregation, composition, realization, generalization) ? § Connection between Blackboard and Student (association, aggregation, composition, realization, generalization) ? § Connection between Blackboard and Classroom (association, aggregation, composition, realization, generalization) ?
