Where exactly is alias used in our day to day life and its advantages. Why to use ALIAS in Production or during implementation?

Also...if suppose there is a table EMP, i create two alias for it based on authorization id.....

Both point to if TEXAS deletes the row from ALIAS will those rows be actually deleted from EMP? Will those rows still be accessible from NEWJERSY.

Though you don't ask about synonyms but referring them here would help, probably.
  • Aliases can refer to local or remote sites while synonyms only to the same sub-system
  • synonyms are not allowed to be qualified
  • alias can be referenced by several users, sys. only by the owner
