   § Source Code in Java – it should compile and run. Carefully review what you are submitting. § Class diagram – it should match 100% the source code submitted § A document describing your decision-making criteria: patterns, relationships, modularization, stepwise refinements, etc.

3. jgs 564 00010100 Announcement Reading: § Components Frameworks and Patterns

   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).

9. jgs 564 00010100 Goal § A system with subsystems §

   Software Reuse Hardware OS Java VM Apache Log4J SLF4J Hadoop Spark nd4j deeplearning4J

10. jgs 564 00010100 Component § Instruction, Statement, § Function, Method

    § Structure, Class, Module § Packages § Components: a software package, a web service, a web resource, or a module that encapsulates a set of related functions (or data)

11. jgs 564 00010100 Relationships § Sequence § Calls and Parameters

    § Association, Aggregation, Composition, Inheritance et al. § Interfaces

12. jgs 564 00010100 Interfaces § 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.

13. jgs 564 00010100 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
