Big Data is the extremely large datasets that their sizes are beyond the ability of capturing, managing, and processing by most software tools and people. Big data the word, or catch-phrase, used to describe a massive volume of both structured and unstructured data that is so large that it's difficult to process using traditional database and software techniques. In most enterprise scenarios the data is too big or it moves too fast or it exceeds current processing capacity. The term big data is also used by vendors, may refer to the technology which includes tools and processes that an organization requires to handle the large amounts of data and storage facilities. The term big data is believed to have originated with Web search companies who had to query very large distributed aggregations of loosely-structured data. But data is expanding faster than ever and now facing big data challenges too. In this paper we are trying to address some of these challenges and their possible solutions.
