Description: Once the world had simple applications. But in today’s world, we have all sorts of data, technology, hardware, and other gadgets. Data comes to us from a myriad of places and comes in many forms. And the volume of data is just crushing. There are three different types of data that an organization uses for analytical purposes. First, there is classical structured data that principally comes from executing transactions. This structured data has been around the longest. Second, there is textual data from emails, call center conversations, contracts, medical records, and elsewhere. Once text was a “black box” that could only be stored but not analyzed by the computer.
