In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...
Larman states that "the critical design tool for software development is a mind well educated in design principles. It is not UML or any other technology." [3]: 272 Thus, the GRASP principles are really a mental toolset, a learning aid to help in the design of object-oriented software.
Design Patterns: Elements of Reusable Object-Oriented Software (1994) is a software engineering book describing software design patterns. The book was written by Erich Gamma , Richard Helm , Ralph Johnson , and John Vlissides , with a foreword by Grady Booch .
Pattern Name: Choosing a clear and descriptive name helps people find the pattern and encourages clear communication between team members during design discussions. Pattern Description: Because short names like "one-window drilldown" are sometimes not sufficient to describe the pattern, a few additional lines of explanation (or a canonical ...
In object-oriented design, the dependency inversion principle is a specific methodology for loosely coupled software modules.When following this principle, the conventional dependency relationships established from high-level, policy-setting modules to low-level, dependency modules are reversed, thus rendering high-level modules independent of the low-level module implementation details.

A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander [ 1 ] and has been adapted for various other disciplines, particularly software engineering .
