The agreed need for technologies from the database domain is therein often referred to as the “Web as a Database”, a concept that is still more a vision than a reality. In this paper we have discussed the Technologies for Web 2.0 Applications. “Web of data” is also called as linked open data. We study the comparison between RDBMS and LOD. DATASET are the space provided online we have listed few of them. We have discussed the components of linked data and standards used in structured data. There is some challenge in linked data.
