Based on the given functional dependencies, let's answer the questions:a . Partial dependencies: - Dependency 2 ( OrderNum - > OrderDate, CustNum, CustFN, CustLN )
Based on the given functional dependencies, let's answer the questions:a Partial dependencies: Dependency OrderNum OrderDate, CustNum, CustFN, CustLN is a partial dependency because OrderNum determines OrderDate, CustNum, CustFN, and CustLN.bNF:To achieve NF we need to identify the primary keys and remove any partial dependencies. Based on the given dependencies, we can identify the following relations:Relation : CUSTOMER CustNum CustFN, CustLNRelation : ORDER OrderNum OrderDate, CustNumRelation : PRODUCT ProdNum ProdDescRelation : ORDERPRODUCT OrderNum ProdNum, UnitPrice, QtyIn this case, the primary keys are underlined, and foreign keys are notated by the relationship between the relations.c Transitive dependencies:There are no transitive dependencies in the relations identified in question bdNF:To achieve NF we need to ensure that there are no transitive dependencies. Since there are no transitive dependencies, the relations identified in question b already satisfy NFI hope this helps! Let me know if you have any more questions.
