One line Description on Design Pattern

Design Pattern:

Observer Pattern     : Weather Monitoring application, Meet the Observer Pattern
Decorator Pattern     : Constructing a Drink Order with Decorators
Factory Pattern        : Define interface to create object
Singleton Pattern     : One Instance, global use
Command Pattern     : Order a Command to do specific process
Adapter design pattern     : (often referred to as the wrapper pattern or simply a wrapper)                 translates one interface for a class into a compatible interface
Facade Pattern         : facade is an object that provides a simplified interface to a                 larger body of code, such as a class library
Method Pattern         : Described how the method will works /steps.
Iterator Pattern    : loop...
Composite Pattern    :
State Pattern        : like scope
Proxy Pattern        : ..
Compound Pattern    : Join all or more patterns together, [patterns of patterns]

Design Pattern

design pattern is a general reusable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved.

Design Pattern Types
Creational
Structural
Behavioral
Concurrency


creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the 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 somehow controlling this object creation.


structural design patterns are design patterns that ease the design by identifying a simple way to realize relationships between entities.

behavioral design patterns are design patterns that identify common communication patterns between objects and realize these patterns. By doing so, these patterns increase flexibility in carrying out this communication.


concurrency patterns are those types of design patterns that deal with multi-threaded programming paradigm.
