Let's look at the situation where one type code cannot be further decomposed. In this example, all employees who are not teachers of any kind are classified as "support." These employees are identified by one type code that is not further decomposed or divided in any way. One way this can be determined is by looking at the programming code. A second, and probably easier, way to determine if there is only one type code is to look at the views defined. A view is a virtual table defined on the base table. In this case, the Support View is defined on the Employee Table. This is illustrated in the diagram below where a selection is made on the type of Support and the columns are displayed.

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.
