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.

What are Design Patterns?

A design pattern is a solution to a problem in a context.

• The context is the situation in which the pattern applies. This should be a recurring situation.

• The problem refers to the goal you are trying to achieve in this context, but it also refers to any constraints that occur in the context.

• The solution is what you’re after: a general design that anyone can apply which resolves the goal and set of constraints.

If you find yourself in a context with a problem that has a goal that is affected by a set of constraints, then you can apply a design that resolves the goal and constraints and leads to a solution.
