[Techies Bytes] Extension to the 4+1 View Model of Software Architecture

[Anjani kumar]

Often people find struggling with the 4 most important Architecture Diagram on Architectural Blueprints of The “4+1” View Model of Software Architecture, why? 


The reason behind this is the advancement and refinement in the way technology has evolved and the way we can interpret and map our thought to technology.


Now a days the power of Agile, TOGAF and mapping it to UML and OMT make's it easy to design artifacts which can be mapped from different levels of pertaining views that can be felt and inscribed as user stories   through different view points.

Creating the Stack holder power grid help us to prioritize stories with perspective's that  are more important for building the system.
The importance of view point help us to derive the use cases easily helping us to draw the functional view of the program.

This would further help us to conclude to the 60,000 feet  view of the program at its component level.
Diving further below to the 30,000 feet  help us to look at the program by mapping to the activities in the use cases to the major component of the system and how they will be mapped at component level which will help us in deriving the required infrastructure and capacity management of the system.
Further comes the security  view  of the system which can be based on number of Human and System actors interacting between inside and outside of the system in term of switching and control, messaging and usage.

Once we clear out all the views  including the infrastructure we can further dig deep to the Development view mapping the classes, objects and interfaces to the use cases, Activity diagram, Process flow diagram (Not limited to UML as flowchart are always the fastest to make and easiest to explain between the involved parties.)
Being strict to  UML we may have to break to sequence and state diagram which are a bit tricky and should be avoided if not much required.
The below example is still in the mode of refinement and lacks the user stories, I will try to update it as soon as I get out from my personal and professional commitments.
