These queries have been designed to allow users full access to the information in each member state's MARIS database. Each query will request information from each member state. Detailed forms allow the user to carefully define each query, allowing very specific data searches.
NOTICE:
The MARIS project is a prototype.
Data included in the databases are real, but may not be
complete.

It is very important to be aware of the metadata before attempting to analyze the results of a query. The member states vary in their methods of data collection and management, which will affect the analysis of data requested from the databases.
