Review  Only two chapters (6 & 7) Normalization Theory Triggers

Chapter 6 Functional dependency (FD); Un/Satisfaction of FD by a relation; Properties of FDs; entailment of a FD by a set of FDs; equivalence between two sets of FDs; Projection of FDs Normal forms: (BCNF, 3NF, 4NF); Decompositions (lossless and lossy, dependency preserving); Multivalued dependency (MVD); properties of MVDs; Algorithms: BCNF, closure computing, 4NF

Chapter 7 Define triggers Determine results of certain events Need to remember a little bit of SQL
