Primary key: BookID, CopyNr and Author

Candidate key: ISBN, CopyNr and Author

Below you see dependencies of attributes:

Dependency 1 (D1): ISBN, Title, PublYear, AuthorBornYear were dependent on BookID, CopyNr, and Author
Dependency 2 (D2): Title and PublYear were dependent on BookID, CopyNr
Dependency 3 (D3): AuthorBornYear was dependent on Author

First determine which normal form (1NF, 2NF, 3NF, or BCNF) the above relation is, and why. Then, if necessary, convert the above relation to the highest normal form (BCNF). Write any assumptions that you make
