There are many hot trends today. One of the most hype one is data! working on data and get value from it, is what every business working on it. There is high demand for people who can mine knowledge from data; And there are many people working on it. But There are certain words needs to be defined. In this article differences between data mining, big data and data science is discussed.
According to wikipedia data mining is: “an interdisciplinary subfield of computer science.It is the computational process of discovering patterns in data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems”. Data mining goal is to find useful information (knowledge) from data which has value for data owner.
Big data as wikipedia says: “Big data is a term for data sets that are so large or complex that traditional data processing applications are inadequate”. The goal of big data and data mining is the same; To find useful information in data which cannot be found by traditional statistics approaches. There are three Vs in big data: Volume, Variety and Velocity. Volume of stored data is very huge these days; It comes from different sources so it is various; And it needs high velocity processing approaches.
Finally data science is “Data science is an interdisciplinary field about processes and systems to extract knowledge or insights from data in various forms, either structured or unstructured, which is a continuation of some of the data analysis fields such as statistics, data mining, and predictive analytics”. So data science is working with data from the first place to the last.
Big data and data mining are almost the same, only big data focus is on working with large data sets, the way they are stored and processed and their problems. Data science according to kdnuggets ,on the other hand, “looks to create models that capture the underlying patterns of complex systems, and codify those models into working applications”.
So we can summarize their difference into this sentence “Collecting Does Not Mean Discovering”.
