We are in the process of developing an Oracle Database and are exploring the possiblities of creating a column that uses the computations of other columns and performs several logical tests of its own. We are wondering how to make this column appear only when we need to run queries against it so that we do not have to populate it and waste space. We believe this is possible but are unsure of how to go about accomplishing it. Any help and/or suggestions would be greatly appreciated. Thank you for your assistance.
