Assignment A1 S18

Submit a PDF on Brightspace with the answers to the questions in Relational Algebra exercises (Word version) using DMV DB. Write the answers clearly using relational algebra notation described in the Widom videos and in class.

The PDF should also be clear. If you do not have access to scanner (do not upload pictures), then type the answers directly into the word file (you can do this anyways), using the Greek symbols and special symbols available in Word, or using alternative notations as described in week 1’s Thursday’s class.

You will need to reference your answers in Tuesday’s class (by hardcopy or electronically). Bring your laptop to class (or have it available if you Zoom in) for uploading commentary on your answers on Tuesday.
