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 eachothereach 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.

As visible in the diagram above, a user is a generalisation generalization of both crewmembers and viewers. A crewmember is able to 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.
