Sensors capable of sensing phenomena at high data rates—on theorder of tens to hundreds of thousands of samples per second—areuseful in many industrial, civil engineering, scientific, networking,and medical applications. In these applications, high-rate streams ofdata produced by sensors must be processed and analyzed using acombination of both event-stream and signal-processing operations.This paper motivates the need for a data management and continu-ous query processing architecture that integrates these two differentdesired classes of functions into a single, unified software system.The key goals of such a system include: the ability to treat a se-quence of samples that constitute a “signal segment” as a basic datatype; ease of writing arbitrary event-stream and signal-processingfuncti
