A recent Run As Radio podcast covered “Disaster Recovery in the Cloud”. Many suggestions weren’t brand new of course, but it was great to have them validated by two of the best people in the field. Anecdotes from personal experience livened up the conversation. I’ve made some notes here, but do listen to the podcast […]
Good luck to anyone who can conjure up a TED lecture out of telling people that it’s impossible to keep up with all the changes these days. You and I knew that already, didn’t we? Agile methods help organisations adapt to change. If successfully applied they increase the rate of change. There was an interesting […]
With Sql Server 2016 you’ll be able to store and return validated JSON from the database. Does this mean you can now consider using Sql Server as a back end to a Node.JS web server? Maybe: but before this becomes a reality you have several chambers to pass through
The JSON has landed (in beta at least) – and I think it’s now some practical use. I’ve collected a few technical references here. There may not be a native JSON type yet, but there are workarounds to provide the kind of assurance control-freak RDBMS developers find comforting. I’ve shown some of them in the […]

Rules on matching can be enforced in the application, but there are often good reasons to place them in the database. In Sql Server, a filtered index (with a WHERE clause, in this case […]

Indexes often double as constraints. Each combination of values must only appear once among the columns of an index defined as UNIQUE. The “filtered” index allows some refinement. Suppose that in one column you won’t allow a specific value to appear more than once, but you don’t mind other values being duplicated. A good example […]
