T-SQL Tuesday #131 – Database Analogies – Star Trek Candy
This month’s #tsql2sday came to us from Rob Volk, who asks us to explain databases using an analogy, as if explaining to a 5 year old. I’m actually a big fan of The Feynman Technique (aka ELI5), so I really wanted to participate. But to be honest, I nearly missed out this time because I couldn’t think of an idea this whole week.

Overriding the Authentication in SSRS for External Access
In this post, I hope to summarize the various methods that we have, in order to get rid of that annoying authentication prompt. Each method has its own advantages and disadvantages in terms of complexity of implementation, versatility, and the level of security that it provides.
