Well, I'm not the original poster; but given that the "purpose" was to practice relational algebra, I'm guessing no: writing queries for Microsoft Access would not serve that purpose. In brief, I am convinced of that based mainly only on the fact that SQL and relational algebra are not the same thing. Writing queries in relational algebra might serve the purpose; but I suspect the original request was for interesting questions (perhaps simplification?), rather than just "write this query" rote work.

Just a guess.
