Design Definition

Design – the process of determination and specification of the architecture and functionality of the whole software system. The provision in this step is to make a user need and business goal transform into a technical blueprint, that emphasizes performance, usability, and maintainability.

Development basically involves the construction of models, diagrams, and prototypes to define the structure of the system; it guides the developers in code and database generation.

This is guided by different design methodologies like object-oriented and component-based designs that control how the system components are organized to facilitate easy development, testing, and maintenance.

It ensures team collaboration, aligning all members on the project’s goals and architecture. Likewise, an application with effective design could be changed over time to meet an evolving requirement as new technologies are brought on stream.

Key principles of design

Strong software design is based on a set of fundamental principles which serve as a guiding light for architects and developers in the process of building stable, scalable systems.

Modularity separates systems into separate, independent parts.

Each module is responsible for a particular function, thus facilitating development, testing, and changes over time without interfering with the application’s other areas not directly related to the one being modified.

The main point of abstraction is to cover up complicated implementation details with easy-to-use interfaces. The use of this principle enables the programmers to deal with the concepts that are on high-level instead of the complex and detailed code, thus lessening the mental effort and also making the work easier.

Scalability is a factor that makes growth happen easily, in a steady manner and even without increment or changes in the quality of the product. Software that is professionally designed and developed is able to bring in new users, handle higher data volumes, and even add new functionality.
