Exploring DBMS Concepts and Applications

What does DBMS stand for?

• Document Base Management System

• Data Backup Management System

• Database Management System

• Digital Business Management Software

What is the primary purpose of a DBMS?

• To create and design new programming languages.

• To provide a user interface for web development.

• To manage hardware resources in a computer system.

• The primary purpose of a DBMS is to manage and facilitate the storage, retrieval, and manipulation of data in databases.

List one advantage of using a DBMS.

• Increased data redundancy

• Simplified data storage

• Faster data retrieval

• Improved data integrity and security.

What is one disadvantage of a DBMS?

• Easy integration with existing systems.

• Faster data retrieval compared to flat files.

• High cost of implementation and maintenance.

• Improved data security and integrity.

How does a DBMS help in data management?

• A DBMS only stores data without any structure.

• A DBMS does not allow multiple users to access data simultaneously.

• A DBMS helps in data management by providing structured data storage, ensuring data integrity, enabling concurrent access, and offering tools for data manipulation and security.

• A DBMS is primarily used for hardware management.

What are the key components of a DBMS?

• Data Warehouse

• Network Protocols

• Key components of a DBMS include Database Engine, Database Schema, Query Processor, Transaction Management System, and User Interface.

• File System

Explain the term 'data independence' in DBMS.

• Data independence is the process of securing data from unauthorized access.

• Data independence means that the database can operate without any user input.

• Data independence is the ability to change the database schema at one level without affecting other levels.

• Data independence refers to the ability to store data in multiple formats.

What is the difference between a relational and a non-relational DBMS?

• Relational DBMS uses tables and SQL; non-relational DBMS uses various formats and is schema-less.

• Relational DBMS is always faster than non-relational DBMS.

• Relational DBMS does not support transactions.

• Non-relational DBMS only uses JSON format.

Name a popular DBMS software.

• MySQL

• SQLite

• Oracle

• PostgreSQL

What role does SQL play in a DBMS?

• SQL is the language used to manage and manipulate data in a DBMS.

• SQL is primarily used for hardware management in a DBMS.

• SQL is a programming language for creating operating systems.

• SQL is used for designing user interfaces in a DBMS.
