Big data sources are repositories of large volumes of data. Using business intelligence applications users can quickly connect to and derive value from these sources. This brings more information to users’ applications without requiring that the data be held in a single repository or cloud vendor proprietary data store.
Examples of big data sources are Amazon Redshift, HP Vertica, and MongoDB. Emerging big data sources – such as analytic/columnar data stores, NoSQL, and Hadoop data repositories – expect to each more than double their rate of adoption and eventually exceed well over 40 percent availability in self-service tools within two years.
