1. Stepwise Refinement • Niklaus Wirth. § Modularity § Function § Function-driven development § Decomposition § What criteria to use in dividing the system into modules? § Task § Steps § Quality attributes § Software Design is …
2. Decomposing Systems into Modules § Module § What criteria to use in dividing the system into modules? § Information Hiding § Data Structure § What is the difference of Function vs Module? § What is the difference of Task vs Responsibility? § Software Design is …
3. Programming in the large § High-cohesion and loose-coupling § Software Design is … § Programming versus Structuring § Development: Many small programs(modules) written by different people. § Architecture: Structuring a large collection of modules to form a "system" § Composition § Decomposition § Accessibility (public, private) § Hierarchy
4. Teaching Object-Oriented Thinking § Designs as an abstract level as having processes, data flows, and data stores, regardless of implementation language or operating environment. § Procedure, Function Method, Module, Unit, System § Class, Object § Task, Responsibility, Collaborator § Encapsulation / Accessibility § Hierarchical Relationships § Composition / Decomposition § Levels § Linking
4. Teaching Object-Oriented Thinking Association Directed Association Reflexive Association Multiplicity Aggregation Composition Generalization Realization
5. Design Patterns § Solutions to software design problems you find again and again in real-world application development. § Reusable designs and interactions between objects. § Behavior, Creation, Structure
6. Software Architecture § Architecture vs Design § Component: a software package, a web service, a web resource, or a module that encapsulates a set of related functions (or data) § Interface § Instruction, Statement, Function, Method, Structure, Class, Module, Packages, § Architectural Patterns
7. Frameworks § What is a Framework? § Library vs Framework § Components + Design + Domain Specific Solution § Inversion of Control: the framework determines the flow of control § Examples (source code)
