Creating Attributes

I l @ ve RuBoard

Many of the attributes of a class are found in the problem statement, the set of system requirements, and the flow of events documentation. They may also be discovered when supplying the definition of a class. Finally, domain expertise is also a good source of attributes for a class. For example, the requirements state that information such as course name, description, and number of credit hours is available in the Course Catalog for a semester. This implies that name , description, and number of credit hours are attributes of the Course class.
