Data vs. Information
? Data
? Raw facts ? Distinct pieces of information, usually formatted in a special way ? Data can exist in a variety of forms -- as numbers or text on pieces of paper, in electronic memory, or as facts stored in a person’s mind ? A collection of facts organized in such a way that they have additional value beyond the value of the facts themselves ? Data when ‘transformed’ becomes Information ? Accurate, complete, economical, flexible, reliable, relevant, simple, timely, verifiable, accessible, secure

? Information

?

System
? A set of elements or components that interact to accomplish goals ? A combination of components working together

?

System Elements
? ? ? ? Inputs Processing mechanisms Outputs Feedback

? ?

System - Movie Elements
? ? ? ? Inputs - Actors, director, staff, sets, equipment Processing - Filming, editing, special effects, Outputs - Finished film delivered to movie studio Goal - Entertaining movie, film awards, profits

?

Efficiency
? A measure of what is produced divided by what is consumed

?

Effectiveness
? A measure of the extent to which a system achieves its goals

?

System performance standard
? A specific objective of the system (good or bad )

? A set of interrelated elements or components that collect (input), manipulate (process), and disseminate (output) data and information and provide a feedback mechanism to meet an objective ? A CBIS (Computer Based Information System) is composed of Hardware, Software, Database, Telecommunications, People, Procedures ? For many companies, IS is the name of the department responsible for computers, networking and data management. Other companies refer to the department as IT (Information Technology) and MIS (Management Information Services).
