ABSTRACT
The Internet has made new sources of vast amount of data available to business executives. Big data is comprised of datasets too large to be handled by traditional database systems. To remain competitive business executives need to adopt the new technologies and techniques emerging due to big data.
Big data includes structured data, semistructured and unstructured data. Structured data 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 hardware objects, including sensors and actuators embedded in physical objects, which are termed the Internet of Things.
Data storage techniques used for big data include multiple clustered network-attached storage (NAS) and object-based storage. Clustered NAS employs storage devices attached to a network. Groups of storage devices attached to different networks are then clustered together. 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-reduce 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 characterized by being basically available, soft state (changeable), and eventually consistent. MongoDB and TerraStore are both NoSQL-related products used for document-oriented applications.
The advent of the age of big data poses opportunities and challenges for businesses. 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
