![]() ![]() ![]() Classes can carry out processes known as operations. ![]() Attributes are values that define a class. The class name is always shown in the first section, the attributes in the second, and operations in the third. Here is a detailed breakdown of the different symbols used when constructing class diagrams. Note that class diagrams don’t depict any interactions between classes. They can be straightforward and easily amended, making them popular in software development planning stages Īccessibility: they don’t require prior knowledge of coding to be understood īy outlining the relationships between classes, it allows for analysis of the system as a whole.Īs mentioned above, and as seen in Diagram 1, classes are represented by rectangular symbols, and different arrows are used to represent the relationship between classes. However, there are also a couple more reasons why class diagrams might be used. A rectangular symbol split shows a class into three sections: class name, attributes, and operations.Īs mentioned earlier, class diagrams are typically used to map out what a system would conceptually look like in static form. A class represents a set of objects that share common characteristics, namely behavior, and structure.
