Regarding Query 4 in Project 2

[Nie@asu.edu]

Folks:

Nie says that he found that Niagara engine still can not fully support
string regular expression match. That means that queries such as giving all
professors whose research interests includes "*datatbases" can not be asked to
the query engine.

Thus the query 4 need only return professors whose interests literally
match the strings "artificial intelligence" and "databases" (thus you will
be missing folks who are working on object oriented databases etc).

Also, in finding the courses offered by the professor, you will have to
join the files by using the professors' last name.
