- C Non-relational database
- D Relational database
Reveal correct answer
Correct answer: D
A. Spreadsheets also use a row and column structure, but they are not as optimized for efficient storage and retrieval of data as relational databases. Spreadsheets are more commonly used for individual data analysis and manipulation rather than large-scale data storage and management.
B. Text files do not have a structured format like rows and columns, making them less suitable for efficient storage and retrieval of structured data compared to relational databases.
C. Non-relational databases do not use the traditional row and column structure for data storage. They are designed to handle unstructured or semi-structured data in a more flexible manner, making them less efficient for structured data storage and retrieval.
D. Relational databases are specifically designed to store and retrieve structured data efficiently using tables with rows and columns. This structured format allows for easy querying, indexing, and relationships between different data entities.
