If you get a Disaster Recovery Plan wrong, it can make an incident into a catastrophe for the business. Hugo Shebbeare discusses some essentials, describes a typical system, and provides sample documentation.

How should SQL code be formatted? What sort of indentation should you use? Should keywords be in upper case? How should lists be lined up? SQL is one of those languages that will execute however you treat whitespace and capitalization. However, the way SQL is laid out will effect its readability and the time taken to review and understand it. Standardisation of code layout is an important issue, but what standard should you adopt?
