Chapter 5. Persistence Architecture
For the ESB bus, persistence is the key element in storing messages that could be associ-
ated as business objects that run through the ESB workflow. There are other persistent ele-
ments that comprise the metadata that define how the messages and workflow are being
handled in the ESB through configuration. Persistence can also be considered the feedback
that the ESB gives to the system in the form of logging, errors, and audits. In this chapter,
we will cover persisting items to the database, including messages and logging.
We will cover the following topics:
• Persistence basics
• Supporting frameworks for persistence
◦ Introduction to Entity Framework
◦ XML serialization
◦ C# reflection
• The PayQueue sample
• The SQL queuing sample
• Database logging
