  1. Introduction to Management Information Systems BUS 3620 Why should you study information systems? How can individuals make better use of technology? How does an organization use information systems? What makes up an information system? What are some career opportunities? What are some ethical challenges? Gerhard Steinke

  2. Core Drivers • Data- Raw facts that describe the characteristics of an event or object (07071991) • Information - Data converted into a meaningful and useful context (student birthdate) • Knowledge- Skills, experience, and expertise coupled with information and intelligence that creates intellectual resources…wisdom (graduate student) • Knowledge worker – Individual valued for their ability to interpret and analyze information

  3. Business Intelligence (BI) / Big Data • Business intelligence - Information collected from within the organization and from sources such as suppliers, customers, competitors, partners,…to find patterns, trends, and relationships for strategic decision making http://www.oracle.com/us/solutions/business-analytics/business-intelligence/overview/index.html https://www.youtube.com/watch?v=7T1iuCNMN1g&index=2&list=PL6gBNP-Fr8KUOyTKNXUHXj1scFmZ_DwRK • Big Data - collection of data sets so large and complex that it becomes difficult to process using current database management tools... The challenges include capture, curation, storage, search, sharing, transfer, analysis,and visualization.
