Database Management Systems Quiz

Translating information into a structured form that can be processed, recorded, and stored by a computer system.

An organized collection of related sets of data that can be accessed and managed as a single unit.

Software used to create, maintain, and access a database. It provides tools for storage, retrieval, and management of data.

A computerized record-keeping system that includes both the DBMS software and the data itself.

The process of transforming data into meaningful information.

Operations that can be performed on a database, including adding, inserting, retrieving, changing, deleting, and removing data.

Various fields where databases are used, including airlines, banking, universities, and telecommunications.

Examples of popular database management systems like Oracle, MySQL, and Microsoft SQL Server.

A specific area of the real world that a database represents, like the student information in a university.

A collection of related data in a database, like 'STUDENTS', 'COURSES', or 'DEPARTMENTS' in a university example.

A connection or relationship between two or more entities in a database. Examples include 'STUDENTS take COURSES' or 'COURSES are offered by DEPARTMENTS'.

A database management system designed for managing and accessing data stored in tables, which relate to each other through shared values.

A collection of data organized into rows and columns, often used in relational databases.

A database application developed by Microsoft, primarily used for personal and small-scale business tasks involving data management.

An open-source database management system known for its efficiency, reliability, and affordability, widely popular for various applications.

A database system developed by Oracle Corporation, known for its ability to handle large amounts of data and complex operations.

A database management system developed by Microsoft, providing a robust platform for data storage and processing.

The ability of a database management system to allow multiple users or programs to access and modify data concurrently without causing data inconsistencies.

A database management system (DBMS) catalog storing the details of the database, including its structure, constraints, and other metadata. It enables the DBMS to work with different databases, even those with varying structures.

Data about data. It describes the structure, characteristics, and other information related to the data stored in a database. This includes things like column names, data types, relationship definitions, and access permissions.

The ability to change the data storage structures or operations without altering the programs that access the database. It allows for data structure modifications without affecting existing software.

A system for retrieving data from a database using structured query language (SQL) or other querying methods. It enables users to find and access specific data based on their needs.

This refers to the ability of a database system to hide various complexities of the data and present a simplified, logical view to users. It helps to make database management less complex.

A description of data, its relationships, and the rules that govern how the data is stored and accessed. It provides a structured representation of the data, facilitating its organization and management.

The ability to display different data views to different users based on their needs. It allows users to access only the relevant information, enhancing data security and usability.

A process that ensures that database transactions occur in a controlled and coordinated manner, even if multiple users are accessing the data simultaneously. It helps to avoid conflicts and ensure data integrity.

A class of systems designed to handle a large number of concurrent transactions in a database. It allows for efficient and reliable online processing of multiple requests.

A set of operations performed on a database as a single unit, ensuring data consistency and integrity. It includes actions like reading, writing, and updating data.

A software system that allows users to create, maintain, and access a database. It provides the tools for storage, retrieval, and management of data. Think of it as a database's control center.

A traditional file management system allows access to single files or tables at a time, while a DBMS can access multiple files or tables simultaneously to make connections between the data. It simplifies data management by creating relationships between data.

Data redundancy occurs when the same information is stored multiple times in a database. DBMS helps reduce redundancy, making data management more efficient.

A DBMS enforces data integrity by ensuring data is accurate and consistent. It uses rules and constraints to prevent errors, like ensuring that a student's age is within a reasonable range.

A DBMS grants different access levels to users based on their roles and permissions. This helps protect sensitive data from unauthorized access, ensuring data security.

A system where data is stored in separate files for different purposes, leading to duplication and potential inconsistencies.

The problem of having the same data stored in multiple files, increasing the risk of errors and inconsistencies.

A centralized approach where all data is stored in a single, organized structure, eliminating redundancy and ensuring consistency.

Traditional file systems are suitable for small businesses and home users due to their simplicity and low cost.

Traditional file systems lack features for multi-user access, making them unsuitable for larger organizations.

Traditional file systems lack features for complex operations like transactions, recovery, and data integrity management.

Databases store data in a way that allows relationships between different sets of data to be defined and represented.

The database schema, which describes the structure and relationships of data, is stored alongside the actual data, allowing the DBMS to efficiently manage the information.

Databases offer a centralized and integrated approach to data management, improving data consistency, reducing redundancy, and enhancing data security.
