Input and output data are described in ARIS at the business level by an object of the Cluster type. Currently, these details serve the purpose of documenting and forwarding requirements only.
Data is modeled in the following model types and exported in the form of XSD files to webMethods for later import.

Models of the eERM (Extended entity relationship model) type represent the data view of a company at the semantic level. In an eERM model, you can represent relationships between entity types using the Relationship type object type. With this object type, you can represent n-level relationship types.
Models of the eERM attribute allocation diagram type serve as assignments for object types of eERM models. eERM attribute allocation diagrams specify the characteristics (attributes) of object types.

The IE Data model corresponds to the notation of the data modeling of the CASE tool Information Engineering Facility (IE) by Texas Instruments Inc. The IE notation does not have proprietary object types for relationships between entity types. Relationships are expressed by connections. It is impossible to use n-level relationship types.
