Summing up the PASS Summit 2016

20161031_131132.jpgThis year I didn’t write my usual daily blog posts during the PASS Summit 2016 as I felt it to be bit too much work with the long days and bit of a jet lag with the 10 hour time difference. Instead I decided to write a post summarizing my experience of the event. Every year, when deciding on what pre-con sessions to take and what regular sessions to attend to I try to think of a theme. This year I decided to go with Big Data and Analytics, as that’s an area of Microsoft Data Platform I’m not terribly familiar with.

The most obvious use case for Temporal Tables is auditing, or at least it is to me, but they can be used for other purposes as well. Some examples are going back in time in case you need to perform a data recovery from an error or a data change operation gone bad, or you might want to use it for reporting purposes.

There are few things about the Temporal Tables that are good to know. First of all the work needed to keep track of the changes is done by the database engine when the system-versioning feature is enabled. Another thing some of you might appreciate is that the feature is available also in Standard Edition. And finally my favorite, it’s actually rather easy to start using the system-versioning as we will discover shortly.

Few thoughts from the Data Driven SQL event

Just finished watching the Data Driven event that was broadcasted live from New York earlier today. As expected there was a lot of information about SQL Server 2016 and quite a few visitors telling how their companies used Microsoft SQL Server in their daily business. And these were some big businesses, having impressive amounts of data and transactions to handle. With SQL Server 2016 Microsoft is giving us a feature packed and complete data platform to work with.
