PASS Summit Day 2 SQL Server Evolution

 The day two keynote was delivered by Hanuma Kodavalla a Microsoft Technical Fellow. 

He started with an interesting quote from 'Adventures of a Mathematician' by Stanislaw Ulam

"It is still an unending source of surprise for me to see how a few scribbles on a blackboard or on a sheet of paper could change the course of human affairs."

Then sharing the papers that started it all and the fact that is the 50th anniversary of Codd's paper this year.  

I was interested to learn that the Microsoft Database Research Group is an extension of the SQL product group. 

He mentioned this paper I read a long time ago “One size fits all": an idea whose time has come and gone  M. StonebrakerU. Cetinteme (2005).  The last 25 years of commercial DBMS development can be summed up in a single phrase: "one size fits all". This phrase refers to the fact that the traditional DBMS architecture (originally designed and optimized for business data processing) has been used to support many data-centric applications with widely varying characteristics and requirements. In this paper, we argue that this concept is no longer applicable to the database market, and that the commercial world will fracture into a collection of independent database engines, some of which may be unified by a common front-end parser.

He went through all the previous versions of SQL with their key features ending with SQL Server 2019.







Another key paper was mentioned





Then moved to discuss newer product features of SQL Azure Serverless and Azure Defender

 


SQL Server secure developments include alway encrypted and secure enclaves.




















Then he mentioned the new ledger enabled tables that will be coming soon.
















This was a session through history leading to strive forwards to realize Codd's and Gray's vision. It will be exciting to see what comes next. A great session for an industry person who is a database researcher.
