During various conferences and user group Meetups I meet tons of new people who keep asking me on a number of topics that can sometimes be challenging for me. In a recent SQL Server Bangalore User Group chapter that I just bumped into an individual who had worked extensively with Oracle and was in transition to moving to SQL Server.

It was never a surprise for me meeting such people. Now this DBA asked me the fundamental difference with how instances are done in Oracle Vs SQL. And he was looking for my advice to when to use what. This was an interesting conversation and I wanted to pen down the same for your future references.

Earlier this week, I had the opportunity to take many different interviews. Most of the DBA and Developers update their resume with various versions of the SQL Server. It seems like everybody had written SQL Server 2005 as one of their expertise. At this point of time, I remembered keyword EXCEPT which was introduced in SQL Server 2005 but not many people know about it. After interviewing, I realized that even after 11 years of release of SQL Server 2005 still most of the people do not know about EXCEPT keyword.

I have been wanting to write about the various operators that govern to use JSON and my first shot has been with: SQL SERVER – Getting started and creating JSON using SQL Server 2016.

[Note from Pinal]: This is a new episode of Notes from the Field series. When I was new to SSAS it took me quite a while to understand the various terminology of SSAS. The reason for the same was, I was from networking background and not familiar with many of the analytical terms. I am sure if you are not familiar with SSAS the very first line of this blog “Analysis Services Perspectives are a feature that enable the designer to control which portions of the data model are exposed to the users.” may be confusing. It is alright if you are not familiar with the concept, the goal of this blog post is to understand what is perspective and how it helps user experience.
