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?
