INPUT: Acxiom Corporation collects 300 million individual demographic records. OUTPUT: Who is going to default on a loan. Q: How do you process this input to output?
INPUT: Disney crowd estimates for 4 parks and 365 days of data. OUTPUT: Best time to visit, best sequence of parks to visit. Q: How do you process this input to output?
BI Systems use information technology (hardware, software, but even algorithms) to find patterns, relationships, and trends. Data (MIS) Information Information (DSS) Good Decisions Information (BI systems) Knowledge
Reporting Tools ◦ Examples: Pivot Charts & Online Analytical Processing Data Mining Algorithms ◦ Examples: Apriori Algorithm for finding association rules Knowledge Management Tools ◦ Examples: IBM’s email knowledge bank
TPS – Transaction Processing Systems PCS – Process Control Systems MIS – Management Information Systems DSS – Decision Support Systems EIS – Executive Information Systems ECS – Enterprise Collaboration Systems
People/Machines (TPS) Data People/Machines (PCS) Data & Routine Decisions Data (MIS) Info. & Routine Decisions Information (DSS) Complex Decisions Information (BI) Knowledge Information (EIS) Strategic Decisions Data & Info (ECS) Data & Info.
Old problem: Too much data ◦ figured out some solutions New problem: Too much information ◦ Moving from info. to knowledge is a bigger problem ◦ Where humans are still needed
Pivot Chart Lab & Logic ◦ We will learn how to make accurate predictions (knowledge) given raw data about behavior ◦ Excel will be our tool Market Basket Lab ◦ We will find the strongest product associations (knowledge) given millions of possibilities (raw data) ◦ Access with be our tool Large companies pay $millions for sophisticate tools to do these things
Intro Lab ◦ Getting to know the procedures CMCC Lab ◦ Word is just a document maker ◦ Google Docs is more of an Information System GIS Lab ◦ First DSS example ◦ Data Information ◦ Tables Maps Reports Excel Lab ◦ More than just an accounting calculator ◦ A tool for automation and information processing ◦ Searching (vlookup) and logic (if statements)
Reading is listed on the schedule Review the lab
