Processing flows of information

摘要: An increasing number of distributed applications requires processing continuously flowing data from geographically sources at unpredictable rate to obtain timely responses complex queries. Examples such come the most disparate fields: wireless sensor networks financial tickers, traffic management click stream inspection.These requirements led development a systems specifically designed process information as flow according set pre-deployed rules. We collectively call them Information Flow Processing (IFP) Systems. Despite having common goal, IFP differ in wide range aspects, including architectures, models, rule languages, and mechanisms.In this tutorial we draw general framework analyze compare results achieved so far area systems. This allows us offer systematic overview topic, favoring communication between different communities, highlighting open issue that still need be addressed research.
