An overview on models presented for big data quality management

Big data is some set of data (datasets) whose growth rate is very high and in short time included so much volume that it will be impossible to receive, store, search, analyze, restore and visualize them by existing data management tools.in contrast to the past, the concept big data in not only on academic and problem solving area such as physical complex simulations, environmental researches and meteorology and etc, but many organizations and big companies both now and future years face to problems related to unstructured big data or the same big data. Based on this very much density of data it is very difficult to assure that information are transferred into the system correctly and the best considered data being used. Therefore, while testing data, examining data quality is one of the most important challenges. In this article some model presented for dataquality examine and finally compare each one operation
