CIS 429—Chapter 9 Enabling the Organization— Decision Making Decision Making • An organization may acquire and store vast amounts of data and ______________ • How can these data be used to make good business decisions? • A _____ is an abstraction (simplification) of reality • An organization can use information to construct a model for decision-making Transaction Processing Systems • Online transaction processing (OLTP) captures and stores basic transactional data • A transaction processing system (TPS) is the system that serves ___________ tasks; for example – Payroll system – Order-entry system • Online __________ processing (OLAP) is the processing of information to create business intelligence to support strategic decision making Decision Support Systems • A decision _________ system (DSS) models information to support managerial decisionmaking • Three quantitative models used by DSSs – What-if analysis • What happens to the output, IF various inputs are changed? • Often performed using ______________ – Sensitivity analysis • How sensitive are the ________ to changes in the inputs? – Goal-seeking analysis • What inputs are necessary to achieve predetermined goals? • A _____ supplies the basic data used by a DSS Executive Information Systems • An EIS is a DSS that supports top-level executive decision-making • Capabilities of many EISs – Consolidation (___________ of information to complex groupings) – Drill-down (acquiring more detailed information when needed) – Slice-and-dice (viewing information from different perspectives) • Digital dashboards – EIS that integrates information from multiple sources, _________ to the individual preferences of executives Artificial Intelligence (AI) • Artificial intelligence is HW and SW that simulates _______ intelligence to solve problems • An AI system is a commercial application of artificial intelligence; types of AI systems are – Expert systems (imitate the reasoning of an expert) – Neural networks (imitate the working of the human ______ by detecting patterns in data or using fuzzy logic) – Genetic algorithms (imitates evolutionary, survival of the fittest processes) – Intelligent ______ (a special-purpose knowledge-based system that performs specific task for a user) Data Mining • Wal-Mart applies to point-of-______ (POS) data to create business intelligence resulting in highly accurate sales forecast by product and store. • Data mining uses existing data sets to create ___________, which are then applied to new data sets. • Types of data mining analysis: – Cluster analysis: divide data into __________ exclusive groups that can then be treated differently – Association detection: degree to which variables are related (e.g., market basket analysis) – Statistical analysis: correlations, distributions, statistical models (e.g., ___________ information for forecasting)
