The purpose of a design pattern identifies the essence of the pattern. The three types of purposes used for classification are: 1. Creational: Patterns that deal with creation of objects. 2. Structural: Patterns that deal with creation of structures form existing objects. 3. Behavioral: Patterns that deal with how classes interact, the variation of behavior, and the assignment of responsibility between objects.

Study Notes
Classifications of Design Patterns
- Design patterns can be classified based on two criteria: purpose and scope.
- The purpose of a design pattern identifies the essence of the pattern.
Purpose of Design Patterns
- There are three types of purposes:
- Creational: deals with creation of objects.
- Structural: deals with creation of structures from existing objects.
- Behavioral: deals with how classes interact, the variation of behavior, and the assignment of responsibility between objects.
Scope of Design Patterns
- The scope criterion captures whether a design pattern primarily applies to classes (during design time) or objects (during run-time).
Creational Patterns
- Deal with creation of objects.
- Abstract the instantiation process.
- Make a system independent of how objects are created, composed, and represented.
