Part 3 is divided into two chapters, which are focused on how to make Web Parts communicate and interact which each other to create new or more advanced solutions. Chapter 14 gives you all the details you need to start building Web Parts that can be connected to other Web Parts. Connected Web Parts can send information from one Web Part, called the provider, to one or more consumer Web Parts.
The final chapter, 15, will show you how to build complete and ready-to-go Web Part pages with connected Web Parts. You’ll learn how to package, deploy, and provision these pages using solution packages. Once you’ve finished reading this chapter, you will know a lot about Web Parts in SharePoint 2010 and you should be ready to build new master pieces.
