Nice content that all APP developers using sql databases should know. But unfortunately these base-level knowledge is vanishing these days.
This was presented at an IDUG (Db2 users group) conference in 2016. But the concepts applies to any SQL/app developer.
Thought to share it here...
have a nice one.
