Answer #1

The essential key of a social table particularly recognizes each record in the table. Along these lines, so as to keep the uniqueness of each record, you cannot have more than one essential key for the table. It can either be an ordinary ascribe that is ensured to be one of a kind, (for example, Social Security Number in a table without any than one record for each individual) or it can be created by the DBMS, (for example, a universally one of a kind identifier, or GUID, in Microsoft SQL Server). Essential keys may comprise of a solitary property or various characteristics in mix.
