Hardware support teams only maintain the hardware in which DBMS works. Rest all, that is ultimate users, administrators, and database designers use DBMS.

A Database Management System (DBMS) is a software system that allows users to efficiently store, retrieve, and manipulate data in a database. It provides an interface between the user and the database, enabling users to interact with the data without needing to understand the underlying technical details.


Ultimate users, also known as end users or regular users, are individuals who access and use the data stored in the database for their daily tasks or operations. They include employees, customers, or any other individuals who rely on the information stored in the database to perform their jobs or make informed decisions.


Administrators are responsible for managing and maintaining the database system. They are typically IT professionals who ensure the smooth functioning of the DBMS and perform tasks such as installing, configuring, and upgrading the software, managing user access and security, optimizing performance, and troubleshooting any issues that may arise.


Database designers are responsible for designing the structure and organization of the database. They analyze the requirements of the end users and create a logical data model that represents the relationships between the different data entities. They also define the schema, tables, and constraints that govern the storage and retrieval of data.


Hardware support teams are responsible for managing and maintaining the physical infrastructure on which the DBMS runs. They ensure that the servers, storage devices, and networking equipment are properly configured, monitored, and maintained to provide optimal performance and reliability.


The correct answer is option 'D', which states that hardware support teams do not use a DBMS. This is because hardware support teams are focused on the physical infrastructure rather than the software aspect of the database system. While they play a crucial role in ensuring the proper functioning of the hardware components, they are not directly involved in using the DBMS software to interact with the data stored in the database.

In summary, all the other options listed (ultimate users, administrators, and database designers) are users of a DBMS, as they interact with the software to access, manage, and design the database. However, hardware support teams are responsible for the physical infrastructure and do not directly use the DBMS software.
