Short Description

An increasing number of distributed applications requires processing continuously flowing data from geographically distributed sources at unpredictable rate to obtain timely responses to complex queries. Examples of such applications come from the most disparate fields: Smart Cities, Social Media Analytics, Sensor Networks, Security, Intelligent Business management, Agile Enterprises, Robotics.

These requirements led to the development of a number of systems specifically designed to process information as a flow. In particular, two models emerged and are today competing: the data stream processing model [1] and the complex event processing model [2]. More recently, the community working on Semantic Web Technologies has proposed his own contribution to the area in the form of stream reasoning systems [3,5].

The course aims at presenting the state of the art of the field and the most recent research results in stream and complex event processing. A particular emphasis will be given to the research conducted at DEIB. The students will gain enough background on the topics to be able to use the tools made available by the academic and industrial community to solve prototypical problems. The exams will consist in reporting the experience in using the tools and in discussing the different trade-offs offered by them.
