SQL Spot – Part 3

The growth spurt of SQL Server 2016 and all its related dimensions is hard to follow. Yet with our SQL spot we try to gather some intel for all SQL Server enthusiasts. As always, we try to share some interesting articles, which crossed our paths recently, either professionally or out of personal interest. The gathered community information addresses a healthy BI perspective, ranging from business to technical insights on various topics: SQL Server news, Power BI, SQL Server BI stack, features, data science topics, accidental DBA stuff and interesting learning or study materials.

I am mainly a BI developer, being an accidental DBA sometimes. So  I like to pick up on the basics of things to help me out in occasions I’m forced to pick up the DBA role. Also, since SP1 a lot of new features became available on standard editions. It is a good idea to have some of the enterprise features’ fundamentals well understood. Tuning and maintenance will provide the basics and a starting point for data analysts to get some insight on the inner workings of SQL Server. All rights go out the great blogging community.
