Summary
After this second consecutive chapter on the data referential service, we now have something that works for most of the necessary features, or at least the ones that are the most important to demonstrate how to record changes. We finished this chapter with testing in order to verify that everything works as expected.
This chapter was also an opportunity to look at the use of standards; the implementation of read capacity has introduced the use of the ODP OASIS-defined standard. Respect for such norms allows much better interoperability and is a must-have feature for any application that seeks to implement MDM.
Creating one data referential service for books was a hard task in itself, hence it required two chapters. In the next chapter, we will deploy this service and then create a second service, which will be a bit more sophisticated (but we will go through the explanation more quickly since the first one was explained in so much detail in this chapter).
