Which type of view can be used to implement data security by restricting access to the data?

  1. A view that has global and local rights to a base table
  2. A view that is secured by a password
  3. A view that selects a subset of the columns
  4. A view that utilizes encryption

A view that selects a subset of the columns can be used to implement data security by restricting access to the data. By limiting the number of columns that can be accessed, the view can control the level of access that different users have to the data.

  4. It provides a zone for administrative data which is used to manage sensitive databases

Answer(s): A

Explanation:

A macro is a named object in Teradata that contains one or more SQL statements, always executed as a single request.
