11. 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

12. 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

13. 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)

17. 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
