Analyze the RDBMSs that you are currently using. What types of relational languages does the system provide? For each of the languages provided, what are the equivalent operations for the eight relational algebra operations defined in Section 5.1?

What will be an ideal response?

This is a small student project, the result of which is dependent on the system analyzed.
However, it is likely that the supported languages will be based around SQL and QBE, in
which case, the student should attempt to map the various SQL clauses to the algebra and
calculus.
