Modularization

Modularization:

Modularization is a technique to divide a software system into multiple discrete and independent modules, which are expected to be capable of carrying out task(s) independently. These modules may work as basic constructs for the entire software. Designers tend to design modules such that they can be executed and/or compiled separately and independently.

Modular design unintentionally follows the rules of ‘divide and conquer’ problem-solving strategy. This is because there are many other benefits attached with the modular design of a software.

Modularity has several key benefits:

• Testing & Debugging

Since each component is self-contained, you mitigate dependency issues. It becomes easy to test each component in isolation by using a mocking or isolation framework.

• Reusability

If you discover you need the same functionality in a new project, you can package the existing functionality into something reusable by multiple projects without copying and pasting the code.

• Extensibility

Your software now runs as a set of independent components connected by an abstraction layer.

Advantage of modularization:

• Smaller components are easier to maintain
• Program can be divided based on functional aspects
• Desired level of abstraction can be brought in the program
• Components with high cohesion can be reused again
