A source system can be a system that provides Omni-Gen with data, a system that consumes data that has been processed by Omni-Gen, or an Omni-Gen system.
Source Metadata allows the user to enrich the definition of a source system by attaching additional facts about that system.
An Integration Point is a defined interaction between two source systems, such as an ETL process that loads data from an external system into one or more Omni-Gen ramp tables.
A Source Mapping associates an integration point with a specific subject in the Omni-Gen model. You can get a full description of a subject using the metadata services described above.
A Source Mapping Item is the atomic mapping between an item in the source mapping and an element of the subject in Omni-Gen, as defined in the IDS document. You can get a full description of an element, using the metadata services described above.
