Write a 1200 word (I am not going to count them) technical report (in MS Word), complete with proper referencing, from the position of a professional business analyst, to address the following: (a) Discuss the important features of data mining tools; and (b) Discuss how data mining can realize the value of a data warehouse. This exercise is from questions 18.13 and 18.14 on page 460 of the textbook. Part 3 – 5 marks The four "V"s of big data are volume, variety, velocity and veracity which reflect the amount of data, the different types, the speed with which it is collected, and the uncertainty relating to its truth. You are a large department store thinking about using big data to understand your customers better. Draw an entity relationship model containing key attributes from a customer's internet browsing activity, your transaction sales database, social media activity and publicly available demographic data on your site (or any other interesting sources – CCTV, telephone). The title of the diagram should contain the purpose of the model, what you are trying to achieve.
