Abstract
The design of "STEAM", Purdue Boiler Makers' stream database system, which allows the processing of continuous and snap-shot queries over data streams is discussed. Nile extends the query processor engine, of a object-relational database management system, PREDATOR, to process continuous queries over data streams. Nile uses several approaches based on window-based operators and W-Expire, for emulating tuple addition to and subtraction from the window content. Nile implements each operator as a separate preemptive system-scheduled thread, with operators communicating with each other through a network of FIFO queues.
