James Rumbaugh, Michael Blaha, William Premerlani, Frederick Eddy, and William Lorensen wrote the book which set the stage for “object modeling” as it would later be practiced. Object-Oriented Modeling and Design was published in 1991. [Rumbaugh, et. al., 1991]. Mr. Rumbaugh went on to be one of the primary authors of UML, but much of what appeared in that language had its precursors in the Object Modeling Technique (OMT) described in this book.
Figure B-10 shows an example of an “object model” in the Object Modeling Technique. The boxes represent classes—sets of similarly defined objects. In this case, each class box is in three sections:
· The name of the class.
· A list of attributes.
