In this particular example, we only want to store each State code in uppercase. Rather than restricting users to entering State codes only in uppercase, we can tell Freedombase to convert each State code entered into uppercase for us, regardless of what casing it was entered in. In the Derivation field for the STATE attribute, enter the calculation UPCASE(STATE). For the sakes of efficiency, enter 1 into both the Derivation Sequence and the Derivation Recurse fields.

This is an example of a very simple calculation. Calculations can be very complex if needed. Both calculations, and the use of the Derivation Sequence and Derivation Recurse fields, are explained in more detail further on in this tutorial; for now, please just enter calculations as defined, without being too concerned about the details, or what else is possible using calculations.
