3. What is data warehousing and data mining? Are the terms related?

Part -2:

Select one of the following topics for discussion:

1. Suppose you want to demonstrate an ERD to someone who has never seen one. Provide a scenario from everyday life that lends itself to an ERD (not from the text!)

o Research the steps necessary to create an ERD and summarize them as if you were explaining them to someone.

o Utilizing those steps, create an ERD that reflects your example.

o In your responses to other students' postings, comment on whether or not you understood the explanation, and whether or not the drawing accurately reflects the example.

o Cite your sources.

Discuss the ethical issues to consider when planning a database. For example, should personal data, such as medical information be stored in the same DBMS that manages employee salary and benefits data?

o Find sources that support your discussion and include the ideas in your post.
