Topic notes
In GATE, Normal Forms questions test a candidate's ability to identify candidate keys, classify relational schemas into appropriate normal forms (such as 3NF and BCNF), and evaluate decomposition properties (lossless join and dependency preservation). Questions combine normal form verification with decomposition analysis, frequently formatted as multi-select questions (MSQs) requiring rigorous evaluation of all properties across both the original and decomposed relations.
