Based on the given functional dependencies, let's answer the questions:a$.$ Partial dependencies:$-$ Dependency $2($OrderNum $->$ OrderDate, CustNum, CustFN, CustLN$)$ is a partial dependency because OrderNum determines OrderDate, CustNum, CustFN, and CustLN.b$.2$NF:To achieve $2$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 $1$: CUSTOMER $($CustNum$,$ CustFN, CustLN$)$Relation $2$: ORDER $($OrderNum$,$ OrderDate, CustNum$)$Relation $3$: PRODUCT $($ProdNum$,$ ProdDesc$)$Relation $4$: ORDER$\_$PRODUCT $($OrderNum$,$ ProdNum, UnitPrice, Qty$)$In 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 b$.$d$.3$NF:To achieve $3$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 $3$NF$.$I hope this helps! Let me know if you have any more questions.
