Modelling Concerns in Data Streaming Systems

This paper discusses the necessity and analysis of the problems emerging from a model of evaluating stream data. In these models, information doesn't take the shape of persistent relations, however rather arrives in multiple, perpetual, fast, time dependent information streams. Additionally retrospection of the past work significant to data stream management systems and recent comes within the space, the paper delves the topics in stream question languages, new needs and challenges in question process, and recursive problems.
