I need web application to calculate some values - prices. Few parameters should be defined by administrator and few should depend on customer. Calculation should not be saved but application should enable multiple users to make calaculation at same time.
Price = A1*(A2+A3+A4)+C1*C2
where Ax are administrator values (same for all customers) and Cx are customer values (depend on customer).
It is needed that administrator could change Ax and Cx values and that they are saved in some tables.
Is it possible to make such application with yii fw and could somebody please give me some clues how to do it?
