Notes
	This use case makes reference to query requests and report requests. The OAIS model distinguishes between a query request and a report request. A query request is a single query on the database, which produces results that are supplied to the requesting party. A report request is a request for information that may require one or more queries to produce the results, and the results are presented in a formatted report. (OAIS 4.1.1.7)
