Software design is the process of defining the architecture, components, interfaces, and data for a software system.

The goal of software design is to create a system that is functional, reliable, efficient, and maintainable.

Software design is an iterative process, and it is often necessary to go back and forth between different levels of abstraction.

There are many different approaches to software design, and the best approach will vary depending on the specific project.

Some of the most common software design principles include modularity, abstraction, encapsulation, and layered architecture.

Software design patterns are reusable solutions to common software design problems.

Software design documentation is used to communicate the design of a software system to the development team and other stakeholders.

Software design is an important part of the software development process, and it can have a significant impact on the quality and success of a software project.
