What is a database? In basic terms, it is an organized collection of data. This data is typically organized to model relevant aspects of reality in a way that supports processes requiring this information (Wikipedia, 2014 ). Our modern life is inundated by their use to store and make usable the massive amounts of data that we now generate. A 2011 study by IBM estimated that our society creates about 2.5 quintillion (1018) bytes of data every day (StorageNewsletter, 2011). Databases allow humanity to use all that data that is generated.
