Domain Model
<Provide a diagram showing important real-situation conceptual classes in the application domain. Do NOT include software classes. Describe each of the conceptual classes in a glossary.>
Image Removed
This is the domain model. It represents all concepts and attributes that are present within Regterschot Racing's desire for our application. This model shows all concepts as yellow squares, with the attributes underneath the concepts they belong to. Between the squares are lines that represent the interaction between the different concepts. The arrow on the lines indicate in which way the concepts interact with each other. Next to the line, near the concepts are numbers and asterisks that represent how many interactions on concept has with another concept. The line between Tab and Graph for example shows us that every 1 tab consists of 0 or more graphs.
An explanation of all terms found in the domain model can be found below.

As visible in the diagram above, a user is a generalization of both crewmembers and viewers. A crewmember can perform certain actions within the domain than a viewer, therefore the user concept has been split. The crewmember and viewer do however have the same attributes as a player, so they will inherit those attributes from the user.
