This term is usually used in the context of semistructured data and/or
heterogeneous data where the user should be able to ask queries without
precisely knowing what the schema is. You could think of, for example,
a query that consists of only some keywords or a question in some
natural language. Based upon that and the actual database schema, the
database can more or less deduce what the exact query should be.
