Well Gregory, I don't know what a "normal" application is.... :-)
However, the first application written in MUMPS using FileManager, and placed into use for paitent care in May 1979, routinely examined the Data Dictionary to discover if any fields had been added or removed. The application then adjusted the data presentation and analysis to reflect these changes. The application was a Food Nutrient Analysis package used to develop diet plans for diabetics who were being treated with a High Fiber, High Carbohydrate diet. Physicians prescribed the desired nutrient profile for the diets, and dietitians used the FNA package together with patient preferences to develop meal plans. The Dietitians were free to add nutrients, remove them and edit the properties of each nutrient. The notion of data dictionary driven application logic was there at the dawn of DHCP. The conceptual development around this principle, and the associated tools, did not take of vigorously, however.
