Design patterns...

• Are reusable in multiple projects.
• Provide the solutions that help to define the system architecture.
• Capture the software engineering experiences.
• Provide transparency to the design of an application.
• Are well-proved and testified solutions since they have been built upon the knowledge and experience of expert software developers.
• Don't guarantee an absolute solution to a problem. They provide clarity to the system architecture and the possibility of building a better system.

Design patterns can be divided in:

• Creational Design Patterns
• Structural Design Patterns
