Design Theory and Normalization (part 2) CSC343 Mark Kazakevich (with slides from Diane Horton, Jeff Ullman) Last time ● We learned about a set of constraints that we can put on a relation called functional dependencies ○ We learned about how to test if an FD follows from a set of FDs using the closure […]
University of Toronto CSC343 Winter 2021 In-class Exercises: Properties of Decompositions 1. A lossy join decomposition. Suppose we have a relation with attributes cdf, name, grade. Here is an instance of that relation: (a) Suppose we were to decompose this into two new relations: R1(cdf, name) and R2(name, grade). Project the data onto those two
