    Book is not in 3NF because non-prime attributes (Publisher Year) are transitively dependent on key [Title, Author]. Book is in 2NF because every non-prime attribute of the table is either dependent on the whole of a candidate key [Title, Author], or on another non prime attribute. In table book, candidate keys are {Title, Author} and {Catalog_no}. A client components installation is also a good option if you administer an instance of SQL Server on a database server, or if you plan to develop SQL Server applications. The client tools option installs the following SQL Server features: backward compatibility components, SQL Server Data Tools, connectivity components, management tools.
