摘要：The Internet has made new sources of vast amount of data executives. Big data is comprised systems. To remain competitive b techniques emerging due to big data Big data includes structured data, semistructured and unstructured are those data formatted for use in a database management system. Semistructured and unstructured data include all types of unformatted data including multimedia and social media content. Big data are also provided by myriad hardwa embedded in physical objects, which Data storage techniques used storage (NAS) and object-based storage. Clustered network. Groups of storage devices attached to different networks are Object-based storage systems distribute sets of objects over a distributed storage system. Hadoop, used to process unstructured and semistructured big data, uses the map paradigm to locate all relevant data then select only the data directly answering the query. NoSQL, MongoDB, and TerraStore process structured big data. NoSQL data is c being basically available, soft state (changeable), and eventually consistent. MongoDB and TerraStore are both NoSQL-related products used for document The advent of the age of big data poses opportunities and challe Previously unavailable forms of data can now be saved, retrieved, and processed. However, changes to hardware, software, and data processing techniques are necessary to employ this new paradigm
