> Traditionally, access control at the row and column level is implemented
> through views. Using views as an access control method works well only when
> access rules, restrictions, and conditions are monolithic and simple. It
> however becomes ineffective when view definitions become too complex because
> of the complexity and granularity of privacy and security policies. It also
> becomes costly when a large number of views must be manually updated and
> maintained. In addition, the ability to update views proves to be
> challenging. As privacy and security policies evolve, required updates to
> views may negatively affect the security logic particularly when database
> applications reference the views directly by name. HIVE row and column access
> control helps resolve all these problems.
