In this session, we are going to discuss
structure design.

And in case of
structure design, we shall try to find out

a well-organized
way to find the solution of the software.

So, structure
design is a conceptualization of problem

into several
well-organized elements of solution.

So, it
is basically concerned with the solution

design, how the
solution will get designed.

Benefits of
structure design is that it gives better

understanding of how the problem is
going to get solved.

Structure
design also makes it simpler for designer

to concentrate
on the problem towards more accuracy.

So, that is the main advantage of
structure design.

Structure design is mostly based on divide
and conquer strategy, where a problem is

broken into several small problems.

And each
small problem is individually solved

until the whole
problem is being solved.

So, as a result of that,
in case of structure design,

we are going to apply
divide and conquer model.

So, what is the divide and conquer model?

This problem will be divided into several
sub-problems and we shall go on solving

those sub-problems until the main solution
is being reached.

The small pieces of problem are solved by
means of solution modules.

Structure design emphasize that these
modules be well-organized in order to

achieve the precise solution of the main
problem.

So, that is why as we are using divide and
conquer method method.

So, if we can solve our sub-problems,
so accumulating those solutions,

we can get the solution of the main
software.

So, structure design emphasizes that these
modules be well-organized in order to

achieve the precise solution of the main
problem.

These modules are arranged in hierarchy
and they communicate with each other.

A good structure design
always follows some rules

for communication
between the multiple modules.

In the earlier videos, we have discussed
what is modularization and why we go for

module-based design.

You can watch that video for the better
understanding of this concept.

And here you see a good structure design
always follows the rules and regulations

for the communication in between multiple
co-operating modules.

So, cohesion grouping of all functionally
related elements.

So, within a module, how the codes and
statements and instructions residing

within a module, how far they are
correlated?

What is the cohesiveness in between?

So, that is known as the cohesion.

And coupling communication between
multiple different modules will decide the

nature of coupling.

A good structure design design has high
cohesion and low coupling arrangements.

In the earlier videos, we have discussed
what is the cohesion, what is the

coupling, what are the different types of
cohesion and coupling types are there.

And always in a good software design,
we always expect high cohesion within the

module statements and instructions and low
coupling in between the modules.

So, in this way, we have defined and we have
discussed more on this structure design.
