System Architecture

Software Architecture Review Architecture describes Fundamental organization and interaction of the system and subsystem components It hides the implementation as much as possible! Should NOT be easily changed Should BE easily scaled

Software Architecture Review What is design? Detailed planning of the software to the lowest levels Such as ….. Flowcharting Function definitions Variable naming Task declarations API’s

Software Architecture Review UML diagram vs model Diagrams describe different views of the model More than one diagram of the same kind may exist A poorly formed model can be seen by incoherent diagrams. (once that don’t agree)

Software Architecture Review

Software Architecture Review Collaboration Object Use Case Class UML Model Diagrams Sequence Deployment Statecharts Component Activity

Software Architecture Review Favorite Architectural Diagrams Use Cases Statecharts Component

Software Architecture Review The bottom line Architecture design improves the design and implementation phases Thought out architecture allows ease of diagnostics, testing and expandability Decreases bugs, time to market and costs Allows for reuse Makes the developers life easier
