#federated database

This idea is not ‘new’ – one can say that federated systems is an old topic. But in fact, in a very heterogeneous environment where businesses (groups) are investing in different solutions, such as Hadoop, relational DW, document-oriented stores (e.g. MongoDB) & legacy OLTP systems – each optimized for different kinds of applications -, such federated capabilities become important. The ability of querying all of your company’s data, independent of where it resides, what format it is stored in, in a performing way is crucial in today’s data-centric world with massive, increasing data volume.
