The backup and restore system in SQL Server hasn't changed a great deal over the years despite a huge growth in the typical size of databases. When disaster strikes, and an important service is taken offline while a restore is performed, there is often time to reflect on whether it might be possible to design databases for a more rapid recovery of the most critical parts of a database application.
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.
During presentations about doing database backups and restores, there seem to be two two types of questions that are commonly asked, Those that come from the floor during the presentation, and those that are asked in private afterwards.

This paper provides a foundation for understanding data replication as well as a discussion of the criteria for selecting an appropriate replication technology.
When a disaster strikes, how will you respond? Will you not only successfully recover, but will you do so with professionalism and grace under pressure? Steve Jones tells you how you can.
Louis Davidson describes why all DBAs should strive to be replaceable, and what that really means.
Author Craig Outcalt gives advice on preparing for the worst with a look at what you should consider putting in your disaster recovery plan and why.
Planning for disaster recovery and business continuity aren't amongst the most exciting IT activities. They are, however, essential and relevant to any Database Administrator who is responsible for the safety and integrity of the companies' data, since data is a key part of business continuity.
The Query Optimiser needs a good estimate of the number of rows likely to be returned by each physical operator in order to select the best query plan from the most likely alternatives. Sometimes these estimates can go so wildly wrong as to result in a very slow query. Joe Sack shows how it can happen with SQL Queries on a data warehouse with a star schema.
