What is the primary condition for a set of functional dependencies to be considered minimal?a.There must be at least one trivial FD presentb.Every FD must have multiple attributes on its right-hand sidec.No FD can be removed without altering the set's meaningd.Any FD can be replaced with another equivalent FD

We have the attributes: {A, B, C, D}.Consider the following functional dependenciesA, B, C -> DA, C -> BB -> A, C, DA, B -> C, DA -> DFind all minimal keys.

What is meant by Functional Dependencies?ARelationships between attributes that determine the values ​​of other attributesBUnexpected error in the databaseCWays to reduce data redundancy

In a schema with attributes A, B, C, D and E following set of functional dependencies are givenA → B A → C CD → E B → D E → AWhich of the following functional dependencies is NOT implied by the above set?*AC → BCCD → ACBC → CDBD → CD

Functional dependencies: implicationWe have the attributes: {A, B, C, D, E, F, G}.Consider the following functional dependenciesA, D, F -> EE, F, G -> DA, B -> FE -> BC, G -> D, FC, G -> B, EA, C -> EA -> C, EMark all functional dependencies that are implied by the dependencies above:A, C -> EA, C -> BA, C -> B, DA, C -> CA, C -> C, F

Consider relation R(A,B,C,D,E) with functional dependencies:AB -> C, C -> D, BD -> EWhich of the following sets of attributes does not functionally determine E?
