            6.4  What Is an Analytic?


            Big data in itself contains little value. The value is there, but it is latent and must
            be activated. Some hold a low opinion of the value of data for this reason. It is
            important, however, to think of data as a raw material, from which something
            very valuable can be created. The real value in collecting and managing big data
            lies in the conduct of analytics that turn the data into information, insights, and
            actionable strategies. This chapter explores the definition of data analytics. In
            particular, it explains the difference between world-class reporting and the use
            of analytics. Making use of a sporting analogy, world-class reporting will only
            ever make you a well-informed spectator at a football match, whereas analytics
            can give you the power to change the performance of the team, just like a coach.
            Examples of analytics that have been applied to transportation and to business
            enterprises beyond transportation will be explained later in Section 6.6.
                 A more formal definition of the term analytic can be found in the Oxford
            English Dictionary [1], in which analytic has the following meanings:

                 • “The  branch  of  logic  which  deals  with  analysis  (see  analytics  n.  1a)
                  (obs.); an analytical system, method, or approach; an analysis.”
                 • “Of, relating to, or in accordance with analysis or analytics; consist-
                  ing in, or distinguished by, the resolution of compounds into their ele-
                  ments.”
                 • “Of a judgment, statement, proposition, etc.: expressing no more in the
                  predicate than is contained in the concept of the subject; true simply
                  in virtue of its meaning or its logical form; having the property that its
                  denial is self-contradictory.”
                 • “Forming part of mathematical analysis (analysis n. 5); relating to or
                  involving mathematical analysis.”
                 • “Of a function: having derivatives of all orders at every point of its do-
                  main (or a specified part of its domain); locally representable by a power
                  series.”
                 • “That analyses or has a tendency to analyse; that is concerned with or
                  characterized by the use of analysis.”
                 • “Characterized by the use of separate words (auxiliaries, prepositions,
                  etc.) rather than inflections to express syntactical relationship.”


                 These definitions indicate that the word analytic can mean a system and
            method or approach to analysis, fundamental truths, or a mathematical analy-
            sis and breaking down of something into its individual elements. From a data
            perspective, an analytic provides insight and understanding that can be used to
