What feature justify using NoSQL over relational database?
Hopefully, the answer is not buzz words or acronyms and is
something truly in the NoSQL databases;
What type of Big Data transaction consistency is required?
Ask if the big data analysis in the NoSQL database needs to
be repeatable and reliable.
Do you realize that a Big Data application using an open source
NoSQL database is going to cost more than a relational database?
I think the first question is great, the second could be a great question if such databases supporting repeatable and re-creatable results2 would actually exist, but the third one convinced me someone has something to sell.
