UML Diagrams

UML stands for Unified Modeling Language. For the organization of our project UML diagrams offer easy insight to connections between classes.

Purpose

The diagrams are normally used in software to show dependencies. They are especially useful in finding errors in the software design process. We are using the UML diagrams for what is called backward design. This means we are creating the UML diagrams after writing code.

Class Based UML Diagrams

These UML Diagrams are class based UML diagrams. There are many different types of diagrams, used for different purposes. In the class diagrams, the arrows show dependencies and how each class affects others. The top section of the box, tells what type of programming language is used, the name of the class, and the package. The next section of the box, lists all of the variables in the class. These variables are represented by their name and type. The last section of the box, lists all the methods and the parameters for those methods.
