SQL SERVER – Understanding Basic Memory Terms of Physical Memory and Virtual Memory

Pinal Dave

SQL

SQL Memory, SQL Server

Recently I had been to an institute to talk about some database concepts to computer science students. Most of these academic engagements get me closer to young minds and this is an awesome way for me to bring some of the industry concepts in a digestible simple format. Trust me, this takes double the preparation I normally do for professional sessions because now I need to make the concepts so simple that even kids of any age and with no knowledge can still get the concepts being explained. A lot of times this is an exercise for me to show how self-learning can be much more rewarding and unique when compared to what text book teaching would look like. In this blog, let me take up the concept around Physical and Virtual memory which took some considerable time for me using a whiteboard. I am sure, you would have also learnt these concepts a while back, but this is a refresher in my opinion for all.

During my previous consulting engagement, I learned something new with SQL Server feature called back up to the URL. Since it was not so clearly documented, I am sharing this with you. In this blog post, let us learn about Azure Resource Manager. If you have not heard about this feature, you can think of it as variation of the SQL backup feature. In this type of backup, the destination would be an Azure storage rather than disk or tape. You can read more about this feature on my previous blog SQL SERVER – Backup to Azure Blob using SQL Server 2014 Management Studio.
