how to create a one-to-one relation ship between two objects in triggers? 
is it possible? i wonder when a hear this from the interviewer in an interveiw. please post the code if solution is there.

And what we can create or don't in sand box. I don't know which can develop in production environment and sandbox . Please give the some Clarificatioon regarding these

i saw in documentation maximum batch size is 200. if we enabled bulk Api its is upto 10000 .
But how we can import more than 50000 - 5M records if it exceed the size? please anyone explain the overall dataloader process

it gives  all records but after press delete button from database it delets but in list it not delets.

i have some confusion working with batch apex. We use batch apex working with larger set of data. give me one example of it and why its methods and implementing class is global?

And what we can create or don't in sand box. I don't know which can develop in production environment and sandbox . Please give the some Clarificatioon regarding these
