A '''relational database''' is a kind [database] (in fact, probably the most
important kind).  Special in that the database ''itself'' supports "search with
complex query" (can combine conditions with boolean operations, even using
intermediate search results for additional queries), which simplifies
parallelization and scaling to very large datasets.
