All of the mentioned views could be looked as an additional layer in the table which enables us to protect intricate or sensitive data based upon our needs.
Explanation:
View is a virtual table which executed a pre compiled query. It is a table in which selective portion of the data can be seen from one or more tables. Queries are not allowed in indexed views and adding column is not possible. Views can be looked as an additional layer in the virtual table which protects sensitive data.
Real time system means that the system is subjected to real time, i.e., response should be guaranteed within a specified timing constraint or system should meet the specified deadline. For example: flight control system, real time monitors etc.
