Explain why tools are used in object modeling.
What will be an ideal response?
Object modeling requires many types of diagrams to represent the proposed system. Creating the diagrams by hand is time consuming and tedious, so systems analysts rely on tools to speed up the process and provide an overall framework for documenting the system components. In addition, tools ensure consistency and provide common links so that once objects are described and used in one part of the design, they can be reused multiple times without further effort.
