Database Management Systems

A university database contains information about professors and the courses they teach. The university has decided to publish this information on the Web and you are in charge of the execution. You are given the following information about the contents of the database:

In the fall semester 1999, the course `Introduction to Database Management Systems" was taught by Professor Ioannidis. The course took place Mondays and Wednesdays from 9−10 a.m. in room 101. The discussion section was held on Fridays from 9−10 a.m. Also in the fall semester 1999, the course `Advanced Database Management Systems" was taught by Professor Carey. Thirty five students took that course which was held in room 110 Tuesdays and Thursdays from 1−2 p.m. In the spring semester 1999, the course `Introduction to Database Management Systems" was taught by U.N. Owen on Tuesdays and Thursdays from 3−4 p.m. in room 110. Sixty three students were enrolled; the discussion section was on Thursdays from 4−5 p.m. The other course taught in the spring semester was `Advanced Database Management Systems" by Professor Ioannidis, Monday, Wednesday, and Friday from 8−9 a.m.

1. Create a well-formed XML document that contains the university database.

2. Create a DTD for your XML document. Make sure that the XML document is valid with respect to this DTD.

3. Write an XML-QL query that lists the name of all professors.

4. Describe the information in a different XML document−a document that has a different structure. Create a corresponding DTD and make sure that the document is valid. Reformulate your XML-QL query that finds the names of all professors to work with the new DTD.
