               CHAPTER 10 – INFORMATION AND KNOWLEDGE MANAGEMENT


               10.1 QPP is a football club. It has recently undertaken a significant amount of
                     research on the actions of spectators who attend matches at its stadium. This
                     data has been stored in a large data warehouse.

                     Analysis of the data has suggested that the average spectator is 35 years old,
                     male and spends approximately $25 on merchandise and food during each
                     match.

                     What type of data mining result most closely matches the information
                     discovered by QPP?

                     A     Association

                     B     Classification


                     C     Sequence

                     D     Forecast


               10.2 GGG is a music streaming site. Its users pay a monthly fee and this allows them
                     access to around two million music tracks.

                     One of GGG’s main selling points is that it creates personalised playlists of
                     tracks that each customer will enjoy.  To create this, GGG has designed a
                     sophisticated algorithm which monitors which tracks customers listen to, as well
                     as asking customers to rate tracks as they listen to them. Finally, GGG’s system
                     periodically asks customers to fill in  questionnaires about the types of music
                     they like to listen to – this is because GGG has found that each customer’s
                     preferences change on a regular basis.

                     GGG holds so much information on its customers it is finding it difficult to find
                     adequate storage space.

                     Which of the following options identifies the feature of Big Data that GGG
                     is struggling to manage?

                     A     Veracity

                     B     Velocity


                     C     Variety

                     D     Volume
