Question 1: What similarities and differences do you see between the data models and query algebras (i.e., the operators and the way they are composed into queries) described in the two papers?

 

Question 2: What are some of the benefits and drawbacks of each approach?

 

Question 3: What are the benefits and drawbacks of a declarative query language over a graphically-specified data-flow?
