MIS Chapter 12
Online Analytical Processing (OLAP)
"Slicing and dicing" data stored in a dimensional format, drilling down in the data to greater detail, and aggregating the data.
Data Mining- two basic operations
(1) Predicting trends and behaviors (2) Identifying previously unknown patterns and relationships.
Multidimensional Analysis
(1) Provides users with a look at what is happening or what has happened. (2) Allows users to analyze data in such a way that they can quickly answer business questions.
Unstructured problems
Are fuzzy, complex problems for which there are no cut-and-dried solutions
Semistructured problems
Are problems in which only some of the decision process phases are structured.
Structured problems
Are routine and repetitive problems for which standard solutions exist.
Real-Time BI
Enables users to employ multidimensional analysis, data mining, and decision support systems to analyze data in real time.
Decisional roles
Entrepreneur, disturbance handler, resource allocator, negotiator.
Interpersonal roles
Figurehead, leader, liaison
Management control
Involves decisions concerning acquiring and using resources efficiently in accomplishing organizational goals.
Strategic planning

Dashboard
Provide rapid access to timely information. Provide direct access to management reports. Are very user friendly and supported by graphics.
Decision
Refers to a choice that individuals and group make among two or more alternatives
Business Intelligence (BI)
Refers to applications and technologies for consolidating, analyzing, and providing access to vast amounts of data to help users make better business and strategic decisions.
Decision Making Process
Systematic process composed of three major phases: intelligence, design and choice (Simon 1977), with the implementation phase added later.
What-if Analysis
The study of the impact of a change in the assumptions (input data) on the proposed solution.
Sensitivity Analysis
The study of the impact that changes in one (or more) parts of a model have on other parts.
Goal-seeking Analysis
The study that attempts to find the value of the inputs necessary to achieve a desired level of output.
Data Mining
mining refers to the process of searching for valuable information in a large database, data warehouse, or data mart.
