Salary DATA Base

[arik]

Hi, I hop you guys can give me some edvice...

I like to create data base of employees(wich i did)

and put inside the salary of each one, every payroll i need to print the list and salary of each one.

The problem is if i will change the salary for someone i cannot print again the salary from the past any more...

I know I need a portal and I know how to use it but

I like to be able that each salary reporrt will be on individual record that designae by date so I can go back to any date of payroll and see the information...any help ?
