Design Concept

What is design concept ?

It is a idea which is used to build software that is easy to understand , update and expand

What are designing principles ?

• Abstractions

• Encapsulation

• Modularity

• Sepration of modules

• Single responsiblity principle

• open / close principle

Abstraction

It only show necessary detail and hide the unnecessary detail

Encpsulation

It only show public data and protect the private data

Modularity:

It break down large system into small and manageable modules

Benefits: Easy maintenance

refininement modularity::
it is a mixture of modularity and refinement in this we devide the moduales into layers and detials each laryers

Separation concern:

It means dividing a system so that each parts handles one specific task

Single responsibility principle:

Each modules should only do one job

Effective and productive

Easy to find error

One/Closed Principle

• Software should be designed in such a way that is scalable

• We can add new feature without modifying existing code

Effective Modular Design:

It means breaking down a big software system into modules which works independent and well together

Effective modular design includes:

Independent: Modules should work on own without depending too much on other

Cohesive: Each module should do one specific job or related task

Reusable: It should be designed in such a way that it can be reused in other project

Scalable:It should be easy to expand
