As part of Simple-Talk's long-running Cribsheet series, they asked William Brewer to write a guide to deployment that described in general terms what is involved in the deployment of a database application, and the sort of issues you're likely to come up against.
There is a certain paradox in being advised to expect the unexpected, but the DBA must plan and prepare in advance to protect their organisation's data assets in the event of an unexpected crisis, and return them to normal operating conditions.

Functionality to help maintain a Disaster/Recovery (D/R) Environment synchronized with production is introduced and the associated challenges are discussed.

A suggested design for creating flight schedules makes querying easy. Includes basic airport and airlines data. Get started now with this tricky query problem.
Part of an effective response to a disaster situation is practice and testing of your skills and procedures. Steve Jones reminds us this is important today.
