ODBMSs allow you to store objects directly without any mapping to different data structures. This is shown in the figure below. Mapping to different data structures is called "impedance mismatch." Impedance mismatch slows down performance on complex data because of the need to map from one data structure (tables) to another (objects). ODBMSs have no impedance mismatch. For more information on impedance mismatch and mapping, see the related content below. More on complex data.

Web Services, Service-Oriented Architectures, and Cloud Computing: The Savvy Manager's Guide (Second Edition)
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.
