Answer 1

when a database record is updated you cannot fetch the old record. What you can do is to create another table and insert the record in there before editing it.

Answer 2

Assuming you have a table in your database, "table A" which is the table you are currently updating, create another table, "table B" that you will be saving the actual data you feel will be needed to do the yearly calculations. Do not forget to add a year column on "table B".
