RAD with regular and high quality language
Efficient IDE
Model oriented
Easy code generation
Very improved Debugger
Swiss knife
but :
Image concept in training context
Important psychological first step
Not widespread language

34. Architecture Design: the Art of Compromise
Modélisation
The final Product Architecture must deal with potentially
contradictory Constraints, which impact Breakdown, e.g. :
Safety, Dependability / Fault Tolerance, Certification…
Time-critical functional Paths
Performances & required [hardware] Resources
Mapping on [existing] hardware, middleware, reference Architecture…
Functional grouping Consistency
Dynamic Behaviour
System Modes & States
Complexity of internal interfaces ViewPoints
Human Factors
Dependency in System Integration
Security
Ease of sub-contracting
Reuse, existing Legacy, Product Line Policy Solution
Modularity, Ability to evolve Architecture
Available technologies, COTS…

Building an appropriate Architecture means finding the
most acceptable Compromise between these Viewpoints
