Patterns in software engineering are recurring solutions to common problems that arise in specific contexts. They can be seen as templates for best practices that can be applied in various situations. Patterns aren't necessarily complete solutions in themselves; rather, they provide a framework that can be adapted to fit the needs of individual applications.

The concept of patterns in software engineering is inspired by the architectural patterns introduced by Christopher Alexander in the 1970s. Software patterns can be categorized into three main levels:

Benefits of Patterns

Common Vocabulary

• Facilitates Communication: When software developers share a common understanding of patterns, they can discuss complex design structures succinctly. Instead of describing every intricate detail of a design, they can reference a pattern, which conveys the same information in a fraction of the time.
• Improved Documentation: Patterns can be referenced in technical documentation, making it more concise and accessible to those familiar with the patterns.
• Onboarding and Training: New team members can ramp up faster when they are acquainted with the patterns in use. It provides them with a structured way to understand the system's architecture and design.
