Which software is used to maintain the database by manipulating the data, record, and files?
Correct answer: D. Database Management System (DBMS}
- A. Query language
- B. Utilities
- C. Data dictionary
- D. Database Management System (DBMS}
Explanation
The answer is (D) Database Management System (DBMS).Here's why the other options are incorrect:A. Query language - A query language like SQL is a tool used to interact with a DBMS and retrieve or manipulate data. It's not the software that manages the database itself.B) Utilities - Utilities are programs that perform specific tasks related to data management, such as data backup or reorganization. They are tools used with a DBMS, not the core software for managing the database.C) Data dictionary - A data dictionary is a collection of metadata that defines and describes the data structures and elements within a database. It's part of the DBMS but not the overall software for managing the database.A Database Management System (DBMS) is the software application that enables users to create, manage, and access data in a centralized repository. It provides a comprehensive suite of functionalities for data definition, manipulation, retrieval, and security. It essentially acts as the control center for your database, handling various tasks such as:Data storage and organization: The DBMS stores data in a structured format, using tables, columns, and data types. It efficiently organizes and indexes data for faster retrieval.Data manipulation: The DBMS allows users to insert, update, and delete data through queries or a graphical user interface.Data retrieval: The DBMS facilitates fetching specific data based on user queries using a query language like SQL.Data security and access control: The DBMS implements security measures to restrict unauthorized access and ensure data integrity.Data concurrency control: The DBMS manages access to shared data by multiple users to prevent conflicts and maintain data consistency.Data backup and recovery: The DBMS provides mechanisms for backing up data and recovering it in case of system failures or data corruption.In essence, a DBMS is the core software for creating, maintaining, and interacting with electronic databases. It offers a comprehensive environment for managing all aspects of your data

About Databases
Databases cover tables, records, fields, keys and relationships, together with database management systems and relational database design. The subject includes primary and foreign keys, normalization, SQL commands such as SELECT, INSERT, UPDATE and DELETE, queries, forms and reports, while distinguishing a database from a spreadsheet used for simple tabular data.
