Which of the following is NOT a type of DBMS?

Step 1: Understand the types of DBMS. Relational DBMS organizes data in tables with rows and columns, using SQL for data manipulation. It is a widely used and standard type. Step 2: Object-Oriented DBMS stores data as objects, similar to object-oriented programming, and supports complex data types. It is also a recognized type. Step 3: Sequential DBMS is not a standard classification. It refers to data access in a linear sequence, but this is not a recognized DBMS model. Step 4: Evaluate the options. Since Relational and Object-Oriented DBMS are valid types, and Sequential DBMS is not, the option stating 'More than one of the above' is incorrect. Step 5: The option 'None of the above' is also incorrect because at least one option (Relational and Object-Oriented) is a valid DBMS type.
