Non-technical users can manage a company’s intellectual property and critical processes without having to plow through hundreds of thousands of lines of code.

When should you use a rules engine?

For software developers, a rule engine is useful only if it liberates them from expressing the rule in the code. In order to avoid this pitfall, it is commonly accepted that we should use rule engines only if appropriate, or not use them at all.

What is a rule engine node?

This node takes a list of user-defined rules and tries to match them to each row in the input table. If a rule matches, its outcome value is added into a new column. The first matching rule in order of definition determines the outcome. Each rule is represented by a line.

1. Advantages of a Rule Engine. Rule engines allow you to say “What to do” not “How to do it”. The key advantage of this point is that using rules can make it easy to express solutions to difficult problems and consequently have those solutions verified (rules are much easier to read then code).
