Question :
Which of the following is not a Schema?
Option 1: View Schema
Option 2: Physical Schema
Option 3: Critical Schema
Option 4: Logical Schema
Correct Answer: Critical Schema
Solution : There are three different sorts of schema: logical, physical, and view.
Logical Schema: This term refers to the database's logical design.
Physical Schema: This term refers to the database's physical design.
View Schema: It specifies the database's design at the view level.
Hence Critical scheme is not schema.
Hence the correct answer is option 3.
