Send data between sheets

Hi all,

I have 4 sheets, 3 of them are to fill in information (They are templates) and the other one is to store the information as database. I would like to have a code that i could transfer information from the 3 sheets to the database one on the next available row. Would anyone help me please.

It can be copy and paste form but the best would you please give me like "Sheet1.value = SheetDatabase.value" ? if that is possible.

Thank you.
