One could say that we are almost at the end of our journey. The DB2 11 Application Developer for z/OS certification test consists of 10 sections so this writing should be the end of the story, right? Well, sort of.
First, thank you if you read these blogs, hopefully you found them interesting and
DB2 for z/OS is no longer about the traditional relational structured data only. The evolution brought us not only binary objects, or XML and JSON, but also other non-structured data living in a distributed file system such as HDFS.
Have you ever thought about using XML in DB2 for z/OS, but were afraid that you would need to study a lot of material before you could actually begin? Don’t worry! You do not need to know much before you start. You can get by with basic DB2 for z/OS knowledge.
This part of the certification test is about the application lifecycle. It is not about the methodology you should adopt, it is about the generic tasks you should consider like testing, verifying the results, test data, and performance. And of course, main focus here is DB2 and SQL.
