Assignment 1:
1. Demonstrate applied knowledge of people, markets, finances, technology and management in a global context of business intelligence practice (data warehouse design, data mining process, data visualisation and performance management) and resulting organisational change and how these apply to implementation of business intelligence in organisation systems and business processes
2. Identify and solve complex organisational problems creatively and practically through the use of business intelligence and critically reflect on how evidence based decision making and sustainable business performance management can effectively address real world problems.
3. Demonstrate the ability to communicate effectively in a clear and concise manner in written report style for senior management with correct and appropriate acknowledgment of main ideas presented and discussed.

Assignment 2 consists of three main tasks and a number of sub tasks
Task 1: Exploratory Data Analysis and Decision Tree Analysis
a) Assignment 2 requires that you research and critically evaluate literature surrounding the problem of effectively assessing loan applications for credit worthiness. Credit worthiness assessment reduces the risks associated with lending by determining which potential loan applications are considered to be good, or alternatively a poor, credit risk and should on that basis be approved or rejected. Good risk management of loan applications can significantly improve the bottom line of financial institutions such as banks, building societies and credit unions. This research will inform your assessment and identification of the key variables in the credit data set which is provided for Assignment 2. Note you should also refer to the data dictionary provided in Appendix A of this document and with the creditdata file as this document defines each of the variables and their range of values.
b) Using RapidMiner Studio data mining tool conduct an exploratory analysis of the creditdata data set on the Assignment 2 folder on course study desk which is provided course study desk to identify what you consider to be top five key variables which contribute to determining whether a potential loan applicant is a good credit risk or a bad credit risk. Note you should also refer to the data dictionary provided in Appendix A of this document and with the creditdata.csv file as this document defines each of the variables and their range of values.
Then using RapidMiner Studio data mining tool build a simple predictive model of Credit risk using a reduced creditdata.csv data set using a DecisionTree.
Discuss each of your five top variables in about 50 words in terms of the results of your exploratory data analysis and discuss the results of your decision tree analysis drawing on the key outputs from RapidMiner Studio data mining tool and the relevant supporting literature on credit assessment and relevant supporting literature on the interpretation of decision trees. Your discussion should also include appropriate statistical analysis results such as graphs and results tables from conducting an exploratory data analysis in the RapidMiner data mining tool with some supporting references on predictive model building and interpretation using Decision Trees in data mining (about 250 words).
Task 2: Data Warehousing and Big Data
A data warehouse is the foundation of any Business Intelligence or Business Analytics initiative. Consider the following scenario a large local government consisting of seven departments with many different data sets residing in each department. They want high level advice on the logical design of a data warehouse that would incorporate big data analytics.
(a) Discuss the possible approaches could be used for designing a data warehouse architecture using Kimball or Inmon’s methodology and provide a high level logical design of a data warehouse architecture. (750 Words)
(b) Discuss how your high level warehouse architecture design in part A could incorporate the capture processing storage and presentation of big data. Your answer here should focus on providing explanation of a revised high level diagrammatic representation of the logical design of your data warehouse including how big data analytics would be incorporated/integrated in the logical design of your data warehouse. (750 words)
Note that the coverage of these concepts in textbook Chapter Data Warehousing is somewhat limited and dated and may not be current thinking for such a fast moving field. Hence you will need to research and critically review the current literature in relation to the concept of data warehouses and different data warehouse design architectures and data warehouse architecture design methodologies in more detail. You will also need to consider how big data is being incorporated/integrated into data warehouses initiatives in order to
provide a comprehensive and informed answer to these sub questions for Task 2.
Task 3 Sales Reports using Tableau Desktop
Task 3 Sales Reports using Tableau Desktop consists of the following sub tasks With the following Excel file SalesSuperstore.xlsx provided on the course study desk
a) Create a report and accompanying graph using Tableau that shows a trend analysis for sales by Product Category over the years 2009 to 2012 and comment on key trends and patterns apparent in this report (About 125 words)
b) Create a report and accompanying graph using Tableau that shows for each Product Category Average Profit and Total Sales for each month over the years 2009 to 2012 and comment on key trends and patterns apparent in this report (About 125 words)
c) Create a geographical map presentation using Tableau that shows graphically the relative size by City within each state, Product Sales for year 2010 and comment on key trends and patterns in this report (About 125 words)
d) Create a report and accompanying graph using Tableau that shows for Product Sub Categories that are technology based Unit Prices, Sales and Profit for each month over the years 2009 to 2012 and comment on key trends and patterns in this report (About 125 words)
