Each pattern describes a problem that occurs over and over again in our environment, and then describes the core solution to that problem, in such a way that you can use the solution a million times over, without ever doing it the same way twice." [3] A pattern language is a network of patterns that call upon one another. Patterns help us ...
Rather, it is a description or a template for solving a particular type of problem that can be deployed in many different situations. Design patterns can be viewed as formalized best practices that the programmer may use to solve common problems when designing a software application or system.
The blackboard pattern provides effective solutions for designing and implementing complex systems where heterogeneous modules have to be dynamically combined to solve a problem. This provides non-functional properties such as: reusability; changeability; robustness. [2]
The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
Solution: The solution should explain "how" to solve the problem, and may include prescriptive checklists, screenshots, or even short videos demonstrating the pattern in action. Rationale: Providing reasons "why" the pattern works will reinforce the solution, though time-pressed developers may prefer to ignore this explanation.
In English, TRIZ is typically rendered as the theory of inventive problem solving. [3] [4] TRIZ developed from a foundation of research into hundreds of thousands of inventions in many fields to produce an approach which defines patterns in inventive solutions and the characteristics of the problems these inventions have overcome.

A sample UML class and sequence diagram for the State design pattern. [2] The state design pattern is one of twenty-three design patterns documented by the Gang of Four that describe how to solve recurring design problems. Such problems cover the design of flexible and reusable object-oriented software, such as objects that are easy to ...
The prototype design pattern is one of the 23 Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse. [2]: 117 The prototype design pattern solves problems like: [3]
