In fact both work exactly similarly. The reason for developing and using alternatively is to see their effects. The selective queries asked of the document centre around, MS(CS) study conducted at the COMSATS institute of Information Technology Lahore. An Elementary Introduction of SPARQL and the use thereof as to how the information can be dug out from the semantic document are introduced. SPARQL has also introduced at elementary level and some queries have been answered using SPARQL with regard to prot g software.
