Comment on DMN Demystified, Part 4. Key Element 3: FEEL by bruce
Blog: Method & Style (Bruce Silver)
Nick, I can’t do justice to this in a comment thread. It needs a separate post, which I will do this week. Instead of saying FEEL reduces the pool of people that can do decision modeling, I would say that if a business person cannot use a particular expression or function, that reduces the richness of decision logic that person can model. In that case we’re limiting it to decision tables. If you just use decision tables for everything, then S-FEEL (the subset of FEEL used in decision tables) is as simple as anything else you might imagine. But table queries, iteration, data validation… they go beyond decision tables. So you need a language. The problem isn’t that other languages do those with simpler syntax. The syntax is just as “complicated” and it’s tool-specific.
