But IMO it would be better to extend the DBMS operators set instead of creating a new application for calculating the Month end.

IMO it is not a division between applications and data management, but data should be managed by specialized systems called DBMS.

In the OO jargon, a DBMS is a very good example of reusable component.

Then we could consider any enterprise database as a view of the world wide database :)

I think that the future is for D like languages, but probably it will be in a distant future.

But I was talking about the present.

Because users always will find something you can not declare in your system.

You will always need the possibility of creating new operators using procedural code.

No because you can not create any user interface only dragging and dropping controls, you also could need to implement some presentation rules with procedural code.
