Data integration provides a uniform view of a set of heterogeneous data sources and facilitates users to query without any knowledge of the underlying heterogeneous data sources. In current era, service oriented architecture and cloud computing together has enabled users to access services over the Internet at a low cost. Cloud computing model provides a layer which is responsible for providing data to the other layers and services i.e., Data-as-a-Service (DaaS) layer. The issue of providing an integrated view of data can be handled using semantic data; the data stored in a way that is understandable by machines and integratable without human intervention.
