Large data as a concept in the IT field has been recognized by many people. As in many aspects of the IT field, new technologies were first used by large enterprises, and then in the late stages of the entire use curve, small and medium enterprises began to use it. Big data seems to have gone through the same process. As large data continues to evolve in the real world, it is gradually being applied to less large data elements. Most standards consider smaller datasets being handled by large data tools in a way that is specific to large data architectures. Still, there is a consensus that there will be more data, not less, in the future.

Victor Maire Schoenberg and Kenneth Couqueil in the big Data age tell us the 4V features of large data, namely volume (mass), velocity (high Speed), produced (variety), veracity (real). Large data must be complex compared to small data. However, complexity is definitely an opportunity, not a problem, for us. 　　In the face of the big data age, how to embrace the big data, from the change of thinking way to begin. From "structured database based on presets" to "without presets ...
