Here’s another angle on big data applied to the world surrounding the common business: graph databases. This is a more natural way to model the complete context of a transaction. It’s a big data problem and every business can benefit from analyzing it.
For example, each business transaction is a node. And each person that touches it, or is responsible for it. Each customer and vendor and the communication with them. And each component of the transaction, such as the product, or serial number. And the billions of relationships between all these nodes.
