A design pattern is a general repeatable solution to a commonly occurring problem in software design. It is a template for how to solve a problem that can be used in many different situations. XML training courses will help you identify and design creational, structural and behavioral patterns.
Different patterns can speed up the development process by providing proven development paradigms. They are also effective communication tools between developers as patterns provide documented software interactions that can be improved upon.
Creational Design Patterns
Creational design patterns deal with object creation mechanisms that create objects relatable to a situation. The basic form of object creation could result in design problems or added complexity to the design. Creational design patterns solve this problem by controlling the object creation.
Structural Design Patterns
Structural design patterns are patterns that simplify the design by identifying a clear way to realize relationships between entities. Structural design patterns use inheritance to write interfaces and define ways to compose objects for new functionality.
Behavioral Design Patterns
Behavioral design patterns are all about class’s objects communication. Behavioral patterns are most specifically concerned with communication between objects.
Developers have mixed opinions about using design patterns. The dilemma stems from the need for patterns to use a language or technique with sufficient abstraction ability. Under ideal factoring, a concept should not be copied, but merely referenced. But if the code is referenced instead of copied, then there is no “pattern” to label and catalog.
The idea of a design pattern is an attempt to standardize what are already accepted best practices. In principle, this makes sense, but in practice, it often results in the unnecessary duplication of code. It is almost always a more efficient solution to use a well factored implementation rather than a “just barely good enough” design pattern.
XML training courses will give more thorough, in depth descriptions of design patterns that will be practiced in class by certified professionals. OBIEE courses are also available and both types of technical courses are available on line.
