SmartCQL: Semantics to Handle Complex Queries over Data Streams

SmartCQL, enhanced version of CQL is developed so as to provide semantics to handle complex queries. Simple SPJ (Select Project Join) queries are no longer useful and the existing CQL supports complex queries only to a certain extent. But the main goal of SmartCQL is to enhance this feature to a large extent. We achieved this goal by providing semantics to handle complex queries like sub queries which was not handled by CQL. We solved the famous Linear Road problem, benchmark for data streams with minimum number of queries as compared to CQL. Here we will show how SmartCQL increased the expressiveness to a greater extent.
