What is a class diagram?

It is the primary building block of Object Oriented Programming. In UML notation, a class diagram is represented with the help of a box containing different elements in three sections. Top part has the class name; the middle part has the class attributes, and the bottom part has the name of the methods that a class can execute. It is about a single class. However, we need to use the concepts of aggregation and composition to set up the relationships between the class.

Essential elements of a UML class diagram assignment

Before you start creating a UML class diagram, you must understand the elements of a class diagram. A class diagram is organized as a class name, attributes and operations. Class name is just a name given to the class, attributes are named properties of a class used for describing the object. Operations are the functions to be performed by the class methods.

Another important element of class diagram is relationships. Without a prior understanding of relationships it is impossible to do class diagram assignment. Relationships are of three kinds. Dependencies, Generalizations and Associations.

  • Dependencies - It is a relationship between two classes where a change in one class leads to the change in dependent class. However, this is a weaker relationship.
  • Generalizations - If you need to connect a subclass to a superclass, generalization is used. The example that will follow has Recurring Payment as a subclass to Payment.
  • Associations - It represents the static relationship between the two classes. For example, a transfer can be made from a bank account or to a bank account. It is generally a verb.

Best practice to create a class diagram without failing at Object Oriented Programming

Class diagram models your entire application. It is used to understand the true intent of application and how the associated classes interact with each other. Hence, creating a class diagram requires you to follow the best practices.

  • The class should have a meaningful name. Object oriented programming language standards recommend using a real world name for a class.
  • Establish relationship between classes in advance.
  • Minimize the properties of a class and remove any unwanted properties.
  • Before you create a class diagram using any tool, you should first create a drafted version of your class diagram on a paper. It helps in removing unwanted relationships and complications.
  • Correctly identify all the relationships and attributes of a class. You can update the relationships later, however, actual implementation can only be done if you have the final version of a class diagram.
