• Key Concepts: 
  Rule Expression Language (REL) is a language used to define rules in the SAP HANA Rules Framework (HAN-AS-RUL). It is a declarative language that allows users to define rules in a simple and intuitive way. The language is based on the concept of “if-then” statements, which are used to define conditions and actions. 
  
  How to use it: 
  To use REL, users must first create a rule set, which is a collection of rules that can be applied to data. Each rule set contains one or more rules, which are defined using the REL syntax. The syntax consists of two parts: the condition and the action. The condition defines the criteria that must be met for the rule to be triggered, while the action defines what should happen when the condition is met. 
  
  Tips & Tricks: 
  When creating rules using REL, it is important to ensure that the conditions and actions are clearly defined. This will help ensure that the rules are applied correctly and consistently. Additionally, it is important to test the rules before deploying them in production. This will help ensure that they are working as expected and will not cause any unexpected issues.
