CASE : Midwest Farm Supplies A Corporate View..........
1a. Describe computer literacy.
Computer literacy is the ability to speak and understand the general " glossary of terms" in the computer "arena". Actual "engineering" of a system is not needed as is memorization of the vocabulary. Computer literacy is like television literacy, you can know the actors and plots, but you have no idea of the methods which actual integrate the two together. Literacy can be accomplished in a small amount of time when compared with implementation, operation, and re-configuring of the peripherals. ~ understanding how things work.
1b. Why does a firm need personnel which are proficient in the use of information technology.
Covered somewhat in above paragraph with the following additions. Proficient means to me that the person or organization is taking a proactive stance on information technology. These organizations will be better suited to fend off competition and loss of market share. The company’s growth has a better chance of success if the upper management takes a proactive stance. Information gathering and usage of is changing almost on a monthly basis. A proactive attitude is what strategy management is about and without (proactive attitude) a company is only waiting to lose market share. It is also better for the employee to be "smart" in case they need to find a new job.
How has the power of PC’s help make client-server possible?
In a word, technology. When IBM did not enforce their patents on the original PC, a complete market was formed and ever since the technology has doubled every three years. Price was an after effect of "cloning" by letting many companies produce components and software for the PC. Within ten years there were tens of millions of PC’s and the market has evolved into what it is today. Each computer now has the power of the mainframe which existed ten years ago. Dumb-Terminals have been replaced with "processing units" which can internally operate and only need the mainframe for storing and distributing only the largest amounts of information. Mainframes still provide the "gathering of data" for management strategic operatives, inventories and security.
How is the sales rep’s knowledge important to the development of an expert system. Use case examples.
The sales rep is the "show piece" of an organization (to the customer). The customer will base their decision most likely on the "form" of the sales-person. Nobody personally knows the customer like the sales-rep and remember the old saying that "nothing happens until the sale". The sales-person knows the education of the buyer as well as the cultural aspects of them. The sales-rep knows the terrain better and by seeing the customer’s operation he can become a part of the system. This possessed information must be used otherwise it is a wasted resource. The actual system analyst cannot "feed the bulldog" ~ optimize the organization’s resources without this input.
Use the sales ordering system to justify either a distributed database or a client-server one for this case.
I believe a distributed database which is updated on a nightly basis. Much like a large retailer of products would have. If something would happen at a single office or the corporate headquarters it would not shut down immediate operations of the "branches" and when brought online be updated to the latest information. In the state that has modern equipment this will be easier than the older equipment which does still exist. With hardware prices as there are (DELL offers a 200 MHz complete system for $2000) , I see little reason not to update the equipment where necessary. Then again, I could be completely wrong.
