3.4 Class Based Models:
Introduction: Class based modeling represents the object that the system will manipulate, the
operations that will be applied to the objects to effect the manipulations, relationships between the
objects, the collaborations that occur between the classes that are defined. To effect the
manipulations, relationships between the objects, these model are used.
Now analyzing the main scenario or the story to get classes:
A user wants to see the GRE examination structure for clear knowledge about GRE. The

those book just by one click. Quantitative section is actually mathematics section.
The Model Test section provide some random word selection and user needed to answer those
Question within time limit. The model test is taken on the Verbal section i.e. Barron’s 1100 word
for GRE. User can save their favorite word in my favorite section and also delete that word from
there. The Admin can modify any information of this apps.
Here the probable classes are
 User
 Structure
 Fixed
 Verbal
 Section
 Vocabulary
 Download
