Computer Systems Laboratory for Decision-Making Support I SEM.: I MOD.: PROF. MASSIMO MAMINO; II MOD.: PROF. GIUSEPPE BOARI II SEM.: I MOD.: PROF. MASSIMO MAMINO; II MOD.: PROF. GABRIELE CANTALUPPI COURSE AIMS To teach students the main methods used to analyse the enormous amounts of data kept in various corporate repositories, which - if duly processed - may be used profitably to define present and future scenarios and support decision-making processes. Particular attention will be paid to methodological and practical aspects, through illustration of real cases and laboratory exercises with the aid of tools widely used in the corporate world. COURSE CONTENT The course entails 60 hours of lessons split between theory (40) and laboratory (20). The theory and laboratory lessons are in turn split into two (20+10)-hour parts: – the first 20 hours of theory are devoted to the information technology aspects of data processing (data acquisition techniques and access to databases, data warehousing) and the application of business intelligence and data mining techniques (on-line analytical processing, decision trees, clustering algorithms and association rules); – the remaining 20 hours of theory are devoted to investigating aspects regarding the application of statistical data analysis methods, with particular attention to the procedures available in MS Excel, including multiple regression analysis, simulation of probability distributions and time series analysis (moving averages, deseasonalisation, exponential smoothing and scenario forecasting).
