What is Big Data?

Big Data is large in quantity, is captured at a rapid rate and is structured or unstructured or some combination of the above. It is difficult to capture and manage data using traditional methods but not in Big data. There is so much hype in this space that there could be an extended debate just about the definition of big data.

Big Data technology is not restricted to large volumes. As of the year2012, clusters that are big are in the 100 Petabyte range.Traditional relational databases,like Informix and DB2, provide proven solutions for structured data. Via extensibility they also manage unstructured data. The Hadoop technology brings new and more accessible programming techniques for working on massive data stores with both structured and unstructured data.
