A common way of accessing object data is by navigation, also known as "traversal." The term is derived from the access patterns for the data structures that are common with object models. Many times these structures are "trees" or "graphs." If you would draw one of these data structures, it might look something like the diagram shown below. Moving from one node in this graph to another node is navigating or traversing the data structure. This navigation is built into object programming languages such as Java or C++. For coding examples of navigation, see how to access data using object-relational mapping.

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.
