@satyanarayana143 Realtime database? I don't know whether there are any.
What exactly do you mean by "real time"? What are your requirements?

I am reading data from blackfin board values of current and voltages for every 10 seconds I want to store data to database while continuously database update is delaying.

So how much data arrives in what period of time? What databases have you tried, how near to keeping up are they? Also, why do you want to put the data into a database, what will you use that for, what services must it supply? We have no idea of what your requirement might be.

every 10 seconds

I woulod not talk about "real time" in this case.
You can use any SQL database you like/need. See https://doc.qt.io/qt-5/qtsql-index.html
Yeasiest is SQLite - it stores the data in a file.
Are you sure you need a database at all?

per 1 minute 1.5MB data will arrive Qsql lite database used it will supply dip voltage and current from which time to which time it has happen

So have you tested that with a SQLite database (assuming you even need one, which you don't say) before asking? Are you suggesting SQLite cannot keep up with 1.5MB per minute, do you think that is likely?
