the modeling technique : Bachman diagrams
- Describe the modeling technique that you were assigned in your own words.
- Find one example of how it is used in the real world and provide it.
- Is it implemented into any commercial database systems? If yes, please give a link to it.
- What querying language would one use to query a database in this format?
- What is the benefit of using this modeling approach? Why is that benefit important?
- What is the drawback or challenge of using this approach? Why is
that challenge a problem for someone who may want to use this technique? - What is the measure of “goodness” for this design? Describe how one would go about measuring goodness for this technique.
- Does this model need special hardware to store the database, or does
it have some unique feature to the way it stores data (essentially how
does it interact with hardware). Include a discussion about the physical
interactions with hardware/storage. - Are there any security concerns about the model? How does it factor
into security. If you feel this doesn’t apply to your model, describe
in general what you have found regarding security and data modeling.
All questions should have an insightful answer. Spent at most
one page, single space answering each question. If you cannot find a
lot of information for one aspect, at least discuss what the general
concerns are for the topic, all of which can be found in your textbook.
DO NOT put “does not apply to my model” for an answer. If you do this,
you will get a lot of points taken off. Answer all questions in a .doc
file or .rtf file. Start each answer on its own page. Cite your work
using IEEE citation method – numbering and copying the URL into a works
cited list will be fine – document where you got it from but don’t
stress about documentation. Remember, some of these answers may need
you to look at ACM.
These papers will use turnitin.com. You can have exact quotes for at
most 10% of the paper. Any more will be graded severely down, possibly
subject to failure.
