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. ** See Also ** [RDBMS]: [SQL]: [Comparing Tcl database abstraction layers]: ** Relational Databases ** ADABASE D: [AdabasTcl] [db2tcl] (DB2): (is it true that DB2's native interface is so close to ODBC that TclODBC can be the basis for a "native" binding?)
