Software Design Patterns

Software design patterns are reusable solutions to common software engineering problems that have been proven to be effective over time. They are general solutions that can be applied to different contexts in software development, and they help to improve the quality, maintainability, and scalability of software systems. Design patterns are not specific to any programming language or technology, but they are rather abstract concepts that can be implemented in different ways. There are several categories of design patterns, including creational, structural, and behavioral patterns, each of which addresses a different aspect of software design. Examples of design patterns include the Singleton pattern, the Observer pattern, and the Factory pattern.
