Oh, I forgot. For some reason, save() wants the variables enclosed in single quotes, so they're strings with the name of the variable rather than the variable itself. I don't know why - it shouldn't be necessary in my opinion - but, for whatever reason, that's the way they do it. So just do this:

save(matFileName, 'D');

save('result.mat', D)      %result.mat will be your database, with a single set of data in it.

sir right now i have a database toolbox how to perform the task

You didn't answer his question: "What is it that you plan to do with the data once you have it in a database?" Plus, there is always example code that comes with toolboxes that explains how to do it. Have you gone through all the examples yet? They should teach you.
