Which of the following statement are correct about database managemen…

The correct answer is option 4- All of the above.

In order to provide security and consistency of data, database is not directly accessible to users: This is true. Databases often restrict direct access to users to maintain security, consistency, and integrity of data.

Any addition or retrieval of information from database is done by user-friendly programs: This is true. Users typically interact with a database through user-friendly applications or interfaces (such as forms, reports, or queries), rather than directly manipulating the database.

Database is referred to as ‘back-end’ while the interactive program, that includes user interface, is termed as ‘front-end’ of a database application: This is correct. In a database system, the database itself is the back-end, and the application with the user interface (UI) that interacts with the database is the front-end.

So, all three statements are correct.
