Support View Equivalent from the Class Hierarchy
To start checking the class hierarchy, look at the Support Class. It inherits
the Name and Date of birth attributes from the Person Class. It also inherits
Hire date from the Employee Class. Querying the Support Class in the object
schema would, therefore, provide exactly the same results as shown in the relational
schema Support View if the
same data were stored in the object class definition. This is shown below.

The Savvy Manager's Guide
Douglas K Barry is also the author of a book that explains Web Services, service-oriented architecture, and Cloud Computing in an
easy-to-understand, non-technical manner.
by Douglas K Barry with David Dick
This is a guide for the savvy manager who wants to capitalize on the wave of change that is occurring with Web Services, service-oriented architecture, and—more recently—Cloud Computing. The changes wrought by these technologies will require both a basic grasp of the technologies and an effective way to deal with how these changes will affect the people who build and use the systems in our organizations. This book covers both issues. Managers at all levels of all organizations must be aware of both the changes that we are now seeing and ways to deal with issues created by those changes.
