E4.5c Using the AIRPORT KLX Table, describe an ex- ample that illustrates the modification anomaly. E4.5d Depict full key functional dependencies, partial functional dependencies (if any), and transitive func- tional dependencies (if any) in the AlIRPORT KLX ID and an Airline Name. • Each terminal at KLX airport has a unique Terminal ID und a fixed Number of Gates. • Each airline is permanently assigned to one (and only one) terminal at the KLX Airport. • Each terminal at KLX Airport can have multiple airlines assigned to it. • Each day (Date), this table records the Number of Departing Flights at KLX Airport for each airline. Table. E4.5e Show the result of normalizing the AIRPORT KLX Table to 2NF. E4.5f Show the result of normalizing the AIRPORT KLX Table to 3NF. E4.5a Using the AIRPORT KLX Table, describe an ex- ample that illustrates the insertion anomaly. E4.5g Using the set of tables resulting from E4.5f, describe how the anomalies shown in E4.5a, E4.5b, and E4.5c are eliminated. Consider the following relation with sample data.
