Codd's paper was prescient and foreshadowed many developments in the relational model. How did the operators he define compare to the relational algebra operators of today (especially see his definition of "join")? "Connection Trap" is interesting concept, and somewhat subtle. Cood had beginnings of the idea of "normal forms" (he only defines 1NF though); but weak redundancy was one notion that did not lead anywhere. Notes: Some notes on the paper
This is a survey paper that covers the query processing architecture, operators, alternatives, advanced issues in great depth.
You are required to read Sections 1 through 5.
Notes: This is also a (short) survey paper. See Feb 24 reading for suggestions on how to write a critique.
Notes: Write a single critique for both the papers combined.
Notes: This is an overview article, and although no summary is required, the next 3-4 papers may be hard to follow without this (or some other equivalent) survey.
