Abstract: The growing impact of Big Data deduces the importance of analyzing vast amount of data with a frequent and rapid rate of growth and change in databases and data warehouses. Due to the different types of data, it requires a specialized merging system to combine variety of data to provide better performance, robustness, flexibility and scalability. Hence, it is important to identify a sophisticated strategy for merging different types of data in a way they provide the best result. This survey study gives an overview of variety of data and analyzed the problem of integrating unstructured data with the traditional structured data. Moreover, tools currently available either analyze the structured data or the unstructured data but not the both. As a consequence, few technologies of Big Data are proposed in survey for integrating variety of data. Present study reviews Big Data technology and other related issue available in the survey.
