This Runtime pattern is a combination of the Portal composite pattern and the Pervasive Device Access Variation 1 runtime pattern.
The personalization server node is part of the application tier and interacts with the Web application server node and the database node.
The personalization services can be implemented to support participatory, predictive and prescriptive personalization. This book will not focus on the Personalization pattern; to get detailed information, refer to the redbook A Portal Composite Pattern Using WebSphere V4.1 , SG24-6869.

The Portal composite pattern is a major part of this Runtime pattern. Portal is the main content provider for most of the pervasive devices. Portal also has the ability to transform the content as necessary.
Note that the Additional Portal Components are less important from the pervasive device access point of view, so components such as Content Management, Collaboration, Search and Indexing are not discussed here. For more information on these components , refer to the redbook A Portal Composite Pattern Using WebSphere V4.1 , SG24-6869.
For details on the rest of the nodes, refer to "Pervasive Device Access Runtime pattern: Variation 1" on page 49.
