Agile Technical Practices (Code smells a code smell is a surface…

- - - - Sequential, the method combine two functions were the output of one is the input of the other. For example, format and validate current GPA.
      - Communicational, a method combines two functions that use the same attributes. For example, calculate current and cumulative GPA.
      - Procedural, the method support multiple weakly related functions. For example, a method that calculates student GPA, print student record, calculate cumulative GPA and print cumulative GPA.
      - Temporal or classical, the method supports multiple related functions in time. Example, initialise all the attributes.
      - Logical, the method supports multiple related functions, but the choice of the specific function is chosen based on a control variable that is passed to the method.
      - Coincidential, the purpose of the method cannot be defined or it performs multiple unrelated functions.
      - Functional, the best, the method performs a single problem related task. Example: calculate GPA
    - - Ideal, the class has not mixed cohesions.
      - Mixed-Role, the class has one or more attributes that relate objects of the class to other objects on the same layer.
      - Mixed-Domain, the class has one or more attributes that relate objects id the class to objects on a different layer.
        Example, a port attribute located in a domain class should be in an architecture class.
      - Mixed-Instance, the class represents two different types and can be separate into two different types.
