Summary
In this chapter, we reviewed the different types of replication available today, and how they are compared. We looked at the different types of Q replication, namely unidirectional/stored procedure/CCD, bidirectional, peer-to-peer, tree replication, and Event Publishing. We discussed various DB2 replication sources including XML data and compressed data and looked at filtering and transformations. Finally, we covered operating Q replication in HADR and DPF environments. Now that we have an overview of what Q replication is, we can look at the Q replication components in more detail, which is what we will do in the next chapter.
