V.2.1 Entity-Relationship Model Definition

Substance Administration Query Information Models consist of a single level that includes all Matching Key Attributes and all Return Key Attributes that may be sent from the SCU to the SCP in the request, and whose values are expected to be returned from the SCP to the SCU in the response (or Query items). The Matching Key Attribute values in the request specify the Query items that are to be returned in the response. All Key Attributes (the Matching Key Attributes and the Return Key Attributes) in the request determine which Attribute values are returned in the response for that Query.
