Assignment #1 (SAD)

Deadline of the assignment will be on monday june 29, 2009.
email me the answer: my email is mary.ann.faustino@gmail.com
the subject should be: assign#1_SAD_STI(family name)

1. Describe the potential links between transaction processing and management information systems. For example, consider an order processing system and a sales analysis system. How would these two systems be related to each other? List the pieces of data in this order processing system that might be used in the sales analysis system. Describe how these pieces of data would be used in the sales analysis system. Would these pieces of data take on new form in the sales analysis system or would they remain the same? Why or why not? What would happen if these two systems were designed independently of each other?

2. Visit an office in your university or in another organization that uses an office automation system. What information processing functions does this system possess? Which ones do people use regularly? Which functions do you believe are under-utilized and why?

The extremely tiny Lingo Wireless Mouse

There’s no question that everyone appreciates a bit of portability. It makes it so that you have far less to carry around and it’s less of a heavy load. Of course sometimes it gets to the point that it’s just a little too portable. Yes, it’s more convenient, but if it makes it more difficult to use, then it kind of defeats the purpose. This mouse is one of those items that might just be a hair too small for some people. However, if you have tiny hands, then perhaps this mouse is a dream come true.

Dareway is a Segway for kids


Kids already have the option to own little miniature cars to ride in with batteries that run for about 20 minutes before they die. They also have electronic scooters and other various items to ride on. Well now kids can own their own kid size version of a Segway, only for them it’s called a Dareway. There is a version for both boys and girls, and it will move them around just like your average Segway. Although I imagine this one is not quite as well built.

Panasonic announces LUMIX DMC-GH1 pricing


Panasonic has finally announced the pricing of its new Micro Four Thirds digital camera, the LUMIX DMC-GH1, where it will hit retail stores sometime early this June for a rather expensive $1,499.95. Well, at that price point, you not only get full High Definition video recording capability, you will also benefit from the inclusion of the LUMIX G VARIO 14-140mm/F4.0-5.8 ASPH/MEGA O.I.S. lens as part of the kit. This new lens will boast a silent motor and continuous auto focusing (AF) capability, making it fundamentally different from standard DSLRs.
