SOLID design principles. Proportion. Design Patterns are time-proven solutions to commonly occurring software design problems. These repeating structures of design and architecture are known as design patterns. The concept of breaking down a design into its components (atoms, molecules, templates & pages) lends itself very well to the goals of a pattern library and leveraged heavily throughout. Principles of Object Oriented Class Design The Open Closed Principle (OCP) 1 A module should be open for extension but closed for modification.

The principles of designs are what we do to or how we organise the elements. In the world of object-oriented programming (OOP), there are many design guidelines, patterns or principles. Architectural principles: Axis, symmetry, rhythm, datum, hierarchy, transformation. Design Principle Design principles provide high level guidelines to design better software applications. Design patterns can speed up the development process by providing time-tested, proven development paradigms. However, it's worthwhile to note that designing a concurrent application is a wide and complex topic, and hence no tutorial can claim to be exhaustive in its treatment. Design patterns are integral in understanding the software architecture in a methodical way. A design pattern is a solution to a problem in a context. "Applying design principles is the key to creating high-quality software!". Abstractions should not depend upon details. The SOLID principles were developed by Robert C. Martin in a 2000 essay, "Design Principles and Design Patterns," although the acronym was coined later by Michael Feathers. At the highest level, there are the architecture patterns that define the overall shape and structure of software applications1. Software Engineering/Software Design .
