Connection to External Data
One of the biggest strengths of the ERIAN system is the option to easily connect rules to external data sources. The first option to connect to external data is the definition and the use of the so-called external off-line parameters of individual rules. The connection and the actual use of these data sources may be done by a business user at their discretion and without the need for IT support. ERIAN also offers an “on-the-fly” option to connect very large or live data sources. To define such connection a certain IT expert knowledge of the use of the ERIAN system is necessary, but no IT knowledge is needed when defining the rules. Besides the typical available data sources ERIAN also offers (within the scope of the given rules), an option to use functional type sources in the form of web services.
