For example, in a business domain model for a retail system, classes might include "Customer," "Product," and "Order." Each of these classes encapsulates attributes (properties of the data) and may contain methods that define operations applicable to the data in that class.

Multiplicities define the potential number of instances in the relationship between different classes but do not organize related data themselves. Understanding classes and their significance
