Big data is defined as “Data sets whose size is beyond the ability of commonly used software tools to capture, manage and process the data within a tolerable elapsed time”
Big Data is a common buzzword in the world of IT nowadays, and it is important to understand what the term means.
Big Data describes the realization of greater business intelligence by storing, processing, and analyzing data that was previously ignored due to the limitations of traditional data management technologies
· Processing: Big data is not just a lot of data to be stored but a data that you require to process and use as part of a business application
· Analysing: Big Data is also the data that you want to analyze (i.e. mine the data) to find information that was otherwise unknown
Example of Big Data
A common aspect of Big Data is that it is often the data that was otherwise ignored in your business because you did not have the capability to store, process and analyze it
For example, your customers’ personal information stored in a RDBMS and used in online transactions is not Big Data; however, the three terabytes of Web log files from millions of visits to your Web site over the last ten years probably is Big Data
