DASHBOARDS Dashboard provides the managers with exactly the information they need in the correct format at the correct time. BI systems are the foundation of dashboard, dashboards and scorecards measure and display what is important. It provide a real time view of data. © 2005 Prentice Hall, Decision Support Systems and Intelligent Systems, 7th Edition, Turban, Aronson, and Liang 5-43

Dashboards © 2005 Prentice Hall, Decision Support Systems and Intelligent Systems, 7th Edition, Turban, Aronson, and Liang 5-45 BI Dashboards have spread to various nonfinancial departments of firms, including sales and customer service. The table below give an example of how dashboard have spread through organizations.

© 2005 Prentice Hall, Decision Support Systems and Intelligent Systems, 7th Edition, Turban, Aronson, and Liang 5-50 OLAP The rules to evaluate OLAP on are : - 1.Accessibility. 2.Transparency. 3.Multimedia conceptual view. 4.Consistence reporting performance. 5.Client – server architecture. 6.Generic dimensionality. 7.Multi- user support. 8.Flexible reporting. 9.Intuitive data manipulation. 10.Unlimited dimension & aggregation level. 11.Unrestricted cross dimensional operation.

© 2005 Prentice Hall, Decision Support Systems and Intelligent Systems, 7th Edition, Turban, Aronson, and Liang 5-52 Data Mining Organizes and employs information and knowledge from databases Statistical, mathematical, artificial intelligence, and machine-learning techniques Automatic and fast Tools look for patterns –Simple models –Intermediate models –Complex Models

How data mining works Data mining discovers information within data warehouses that queries and reports can’t effectively reveal. Data mining tools find pattern in data, there are 3 types of methods to identify patterns in data:- Simple models (SQL- based query, OLAP, human judgment) Intermediate models (regression, decision tree, clustering) Complex models (neural network) © 2005 Prentice Hall, Decision Support Systems and Intelligent Systems, 7th Edition, Turban, Aronson, and Liang 5-53

© 2005 Prentice Hall, Decision Support Systems and Intelligent Systems, 7th Edition, Turban, Aronson, and Liang 5-54 Data Mining Data mining solving these classes of problems –Classification –Clustering –Association –Sequencing // like association but over a period of time. –Regression // form of estimation. –Forecasting –Others Hypothesis (we assume a situation & start investigation) or discovery driven (it come from the facts).
