user41994: I want to create a database on Blockchain which gets input from a HTML form and add a tuple to table on Blockchain on each submission.The Tuples on Blockchain will be sorted by applying some operations on it and constraints of visibility of data for certain period of time. I had tried almost all available on internet but no platform provides such functionality and i can't find any relevant tutorials for the same.  

user5292: That makes no sense at all. The blockchain is not a database or a place where you store arbitrary data. The few bytes you may try to weasel in will be very expensive, so your application will be useless.
You're following "blockchain" buzzword hype sales talk that does not make sense and is simply a lie. Don't fall for it.
Look to MySQL or PostgresSQL or NoSQL or similar.
