Rule and Parameter Repository
ERIAN stores valuable business data and knowledge in a well-structured and comprehensible repository. Under the repository the life cycle of individual rules, including the development, testing and release to production, is fully controlled by the user. Besides the actual rules, the repository also stores the so-called external parameters of certain rules. External parameters offer a very efficient method to connect rules to the surrounding world enabling you to implement, for example, seasonal price changes, new product updates and many other features without changing the actual rules.
