In this paper, we present MashQL, a novel query formulation language also called as Query-by-diagram language for querying and mashing up structured data on the Web. It doesn’t require users to know the queried data’s structure. Being a language not merely an interface and assuming data to be schema-free is one of the key challenges addressed in this paper. Assuming web data as input in RDF format used to represent the metadata of the Web applications in structured manner. We can query by using SPARQL language which is the recent recommendation of W3C. By using this approach we mentioned how user having less technical knowledge is able to retrieve the data in structured format. We mentioned that how retrieval results will be faster by providing keyword search and then use MashQL approach. We mentioned the basic concepts for study of MashQL that is mashup, SPARQL, RDF in MashQL by which user can perform a calculation on a set of values and return a single value. A novel technique for optimizing queries over large data sets to allow instant user interaction is proposed and evaluated.
