6. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 6 Design § Sequence § Calls and Parameters § Association, Aggregation, Composition, Inheritance et al. § Interfaces
7. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 7 David Garlan and Mary Shaw § As the size of software systems increases, the algorithms and data structures of the computation no longer constitute the major design problems § Architectural representations can improve our understanding of complex software systems § Just as good programmers recognized useful data structures in the late 1960s, good software system designers now recognize useful system organizations (1994).
8. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 8 Architecture § protocols for communication, § synchronization, and data access; § functionality to design elements; § physical distribution; § composition of design elements; § scaling and performance; and § selection among design alternatives.
9. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 9 Architectural Patterns § Model-view-controller pattern § Layered pattern § Client-server pattern § Master-slave pattern § Pipe-filter pattern § Broker pattern § Peer-to-peer pattern § Event-bus pattern § Blackboard pattern
10. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 10 Goal § A system with subsystems § Software Reuse Hardware OS Java VM Apache Log4J SLF4J Hadoop Spark nd4j deeplearning4J
11. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 11 Johnson et al. § Component represent code reuse A framework is a reusable design represented by a set of components and the way they interact. A framework implement an architecture § Framework = Components + Design + Domain Specific Solution
12. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 12 Framework vs Library § Inversion of Control: the framework determines the flow of control i.e., reuse of main § Model-View-Controller - a framework or an architectural pattern?
13. jgs Javier Gonzalez-Sanchez | CSC 509 | Fall 2023 | 13 § Library § Framework § Platform § API Explain
