For purposes of interfacing, writing scripts or end user reporting, there are a number of data base functions that can be used - both from Oracle and those created as part of the application. As well, customers could create their own custom data base function for this purpose.

The functions listed below are those found to be useful in the creation of interfaces, conversion, script writing or reporting. It is not an exhaustive list, and can certainly be extended by a customer adding their own functions.
