A query is essentially a question you ask the database in order to find specific information. The results of the query can be displayed as a subset of your database table(s) or as a separate report.
A software tool developed for MERS-TM that enables a more in-depth look at local events is called CompareWare.
Using CompareWare, two types of event comparison results can be produced:
Identification of events with certain data elements in common (Query By Field)
Identification of events that are similar to an event of interest (using "fuzzy" matching) (HAWK)
