Nice presentation. How do we transform data or apply business logic on the data? I mean like creating stored procedures to merge data from different tables, I need the transformed data(after applying business logic) to be exported to business users on demand. Can we do this is serverless pool? Ours is a small company. But, we have data coming from number of sources. How does this replaces sql server
Just a note, Ctrl+Shift+R pings all objects on the servers you're connected too. This can actually cause issues with other code running concurrently, such as building an index. Found this out the hard way when my boss asked me why I kept running code that jacked up his processes :)
Thank you very much for this video. I'm a student of applied sciences and I'm very interested in becoming a datascientist. Your video was very interesting with lots of useful information. :D
Excellent Presentation, an Inspiration, Unique concepts. Please keep it up so folks like here can watch and learn significant Data concepts for free and comment their ideaology, appreciate your efforts. Thank you, much Obliged.

it takes a lot of effort to put this kind of video. we will only know the pain, if we create such a video. it is very easy to comment. I think she has done an excellent job.
