Big Data

Database Scalability, SQL Server

Since I have started my consulting engagements with customers around the world, I have been asked interesting queries from time to time. In a recent customer call, the customer insisted I assist them in taking a call on if they need to buy one server with 64 cores or if they need to buy 2 servers of 32 cores. I had to explain that it is always not that simple to answer the same. After close to 30 mins of conversation they understood finally what I was talking. I took a moment to blog about this engaging conversation about database scalability.

SQL Interview Questions and Answers

SQL Scripts, SQL Server

I do a performance tuning consulting to earn my livelihood. Once in a while, I end up customer who wants to interview me to check if I know SQL. I absolutely have no problem with the interview. This is a good thing and it gives me confidence that they are serious with their project. With said that once in a while the senior guys on the other side are so busy they end up having my interview with junior (novice) experts. I often struggle with this interview question and answer with beginners because my answers are based on experience and they often do not match what they have learned in school/collage.
