In earlier chapters, we discussed in detail the functional capabilities of BizTalk Messaging and BizTalk Orchestration. You learned how to send a document to BizTalk Messaging, transform that document, and then finally route the processed document to an internal and/or external application. You also learned how to design and orchestrate a business process using the BizTalk Orchestration Designer. What we didn't discuss was business scenarios that require both categories of services—reliable document delivery and transformation as well as business process orchestration. This chapter focuses on business integration scenarios that require the integration of BizTalk Messaging and Orchestration services as well as long-running business processes that require the synchronization of schedule instances that have been previously dehydrated.
