Popis: Database systems can be difficult to use. Part of the problem is that systems do not, for the most part, help a user when a query fails or fails to evaluate as the user expects. Schema and semantics of databases are often complex, and are rarely understood in entirety by the lay user. As a consequence, queries a lay user casts may not make sense with respect to a database's semantics. A system which returns informative responses beyond a query's answer set itself can elucidate the schema and semantics of the database, which can greatly help the user to cast the queries intended. Such a database system is to be called a cooperative database system (CDBS).
