Abstract and Refinement (1 Viewer)

What is an abstract and refinement diagram?

 

[Fosweb]

Hierarchial view of a system: like - (and i always get confused between abstraction and refinement), but:

Breaks the system down into a number of simpler modules, and then this diagram will lay them out sequentially (top to bottom and left to right along each row)

Its like a tree diagram, with boxes for each module.
This kind of thing I think:

is that like stepwise refinement but in a graphical manner or something rite?

What topic is this from?

 

[fatmuscle]

the algorithms one I thikn

how you break down (top bottom) or vice verca

Where did you see this term used? It's not in the syllabus.

One would tend to assume it is referrring to something like a structure diagram. Structures diagrams show the refinement of the problem into a hierarchy of subroutines. They also show the parameters used to pass data, this facilitates the abstraction process. Abstraction being the ability to remove and solve one part of the problem in isolation to the larger problem.

Sweet. Nice definition.

I got it from my teacher ages ago

yeah, I remember reading it in SDD somewhere.

probably in chapter 9... meh i do hardware - its tons better

Ive found an answer like the above post...

• Abstraction is the process of starting out with a simple idea and elaborating on it
• Abstraction uses the process of refinement to design more detailed solutions
