A Design Pattern is a description or template for how to solve a problem that can be used in many different situations. A design principle is a basic tool or technique that can be applied to designing or writing code to make that code more maintainable, flexible, or extensible. This course approaches software design from three perspectives: the software engineering principles that enable the development of quality software, modeling of software elements using the Unified Modeling Language (UML), and the application of design patterns as a means of reusing design models that are accepted best practices. It is a description or template for how to solve a problem that can be used in many different situations. Principles of Object-Oriented Design.
