Consider the following relation R, where {A, B} is its PK. Assume that R is in the first normal form (INF). R (A, B, C, D, E, F) Functional dependencies: FD1: BàC FD2: AàDE FD3: ABàF Why is this table not in 2NF? Specify which FDs make R violate 2NF. Normalize the data shown in this table to second normal form (2NF). Specify the primary and foreign key (if any) in each table of your 3NF relations. Normalize the data...
Write the complete proof.
Consider the relational schemas given below and the respective sets of functional dependencies valid in the schemas For each one of the relational schemas, determine the highest normal form, which is valid for a schema. Justify your answer If a schema is not in BCNF, then decompose it into a minimum number of schemas so that each one of them is in BCNF. Justify your answers. Justification must include the derivations of minimal keys from the...

Consider a relation R with five attributes A, B, C, D, and E. You are given the following functional dependencies: A → B, BC→E, and ED→A. (a) Is R in BCNF? If it is not, decompose it into a collection of BCNF relations. 2: BCNF and 3NF (3 points) Consider the relation schema R with attributes A, B, C, and D and the following functional dependencies: AB→C, AC→B, B→D, BC→A. (a) Is R in BCNF? If it is not, decompose...
Normalization Please explain the following concepts with specific example and process thank you a) Problem of redundancy: Update Anomalies: Insertion, Deletion and Modification b) Functional dependencies, full functional dependency, Determinant(Candidate key) c) Normal Forms : 1NF, 2NF, 3NF (Definitions and application, given a table check its normal form. Convert the table to a specific normal form.)
Databases Consider the following functional dependencies that hold on R(ABCDEF): AB-> CD, E -> C, B -> EF a) Is R in 3NF? b) Explain your answer in detail and decompose the relation, as necessary, into a collection of relations that are in 3NF. c) Make sure you first find all the key(s) of R so that you will be able to tell whether an attribute is prime. *Please answer all parts of this question in detail for credit.

Consider the following schema and functional dependencies: SHIPPING (ShipName, ShipType, VoyageID, Cargo, Port, ArrivalDate) Key: ShipName, ArrivalDate FD1: ShipName > ShipType FD2: VoyageID > ShipName, Cargo FD3: ShipName, ArrivalDate > VoyageId, Port 1.Please list the final set of 3NF schema including all its keys. 2.Do any of the finalized 3NF schema have determinates that are not candidate keys? If yes, explain - which schema(s)? Why?
Determine the functional dependencies that exist in the following table and then convert the following table to an equivalent collection of tables that are in third normal form. Please show each step from first to third normal form.
