Challenge Question Number 1 for Senior Manager of Technical ServicesRelated Subject(s):Business & Accounting Studies Mathematics Related Soft Skill(s): Analyzing Information Decision Making Describe a typical "challenge" encountered in your work: A business person from your company has come to you asking what would be the best way to store the data for a new application he is having developed. As the Database Administrator, you have five different storage options available to you: Magnetic tape CD-ROM Zip disk Hard disk Floppy disk
During your interview with him, you uncover the following information:
This application will have only one user initially but will likely grow to ten users over time. The growth, however, will be slow. It may take as many as five years to reach that ten-user mark.
In addition to the file that will be accessed during the day, the data will need to be backed up nightly. Unlike the main file, this backup will never need to be accessed by multiple users.
The initial size of the data file will be 600 Meg and will grow at the rate of 500 Meg per year.
Every year end, ten percent of the data will be deleted.
Your client has only $14,000 available to pay for the first three years of storage costs but is certain more will be available if this venture is successful.
Your company has a CD tower on its network that can handle up to three CDs.
In addition, you have the following information:
Clearly describe what you expect from the students: What do you recommend?
How far forward can you effectively plan when business requirements and technology change so rapidly?
What level of risk is your company willing to take?
How well do you trust the estimates provided?
Which is worse--being over budget or having a system that is undersized?
In order to give the teacher some guidance in evaluating the student's project(s); list some tips that may help to assess the student's work: Students should discuss the questions and make decisions based on the information provided to them. Solutions may vary based on student input. |
