This concept is something that the PICK world needs to look at. Intersystems Cache deals with Data Objects which is a combination of data and business logic. That data object is written once and used everywhere from a query, from in a program, from a web services, from .Net, java, etc. This appears to work quite efficiently in Cache although I have not had the chance to play with it.
I am sure that I am not the only developer out there who has explored this concept in PICK and thought it would be highly effective if it could be done efficiently. Consider Total Price = Qty * Unit Price. This would be duplicated in an application from an Enqlish statement to a data entry program, to report programs to a web client, etc. Every one duplicating the reading of Qty and Unit price from the database and writing the calculation for each application. Consider now we need to add tax or a customer discount, that logic would need to be duplicated through every program, wouldn't it be nice if we just had to change it in one place. Maybe this is a future development direction for the IBM folks to consider.
