Info Systems for Management. Professor is Hien Tran. I was running late; he was already started when I arrived. His clock looks to be about five minutes faster than mine.

Homework and computer projects are worth 40% of grade. WebCT quizzes are worth 20% of grade. Two tests, no final exam. Tests are worth 40%.
Homework/WebCT projects will be due at 11:45 PM on date due. Assignment must be named using format “T_Chap_X_Case_Y.xxx”. T is type; valid types are E for Excel and A for Access. X is the chapter number. Y is the case number. xxx is the appropriate file extension.

Looks like quite a bit of this class is going to be done via WebCT. There is, in fact, a strong online component to the class from the looks of things. WebCT looks to be a pretty standard web-interface to a fancy email + database system. Somewhat similar to V-Tiger, conceptually, but hopefully less stupid and broken. Marketing class makes a little use of WebCT, too.

Professor actually claims he has no problem with people doing everything online, teaching themselves, and only showing up for the tests. I do not foresee that strategy turning out well for me.

Chapter 1: Business Information Systems,

Information systems are used to aid in making sound decisions and solving problems. The largest gain for using automated systems is in data collection. Bar codes, credit card systems, RFID systems, electronic time clock systems, and so forth.

Automated systems reduce error rates. Errors are inevitable, but volume of errors can be controlled.

Information systems greatly aid in inexpensively gathering correct information, storing large volumes of information, and putting that information to use.

Raw data is difficult to work with. It accumulates rapidly. Not all information is useful at any given moment.

The Four Stages of Processing

  1. Input — Collect and introduce data to system
  2. Data Processing — perform calculations/operations on input data
  3. Output — results of processing reported or utilized
  4. Storage — data from various steps archived for later processing
