Which of the following statements is FALSE?
Big data can be stored and analysed using database management systems
Big data includes datasets containing billions to trillions of records
Big data can be stored and analysed using a Hadoop cluster
Big data includes data sets containing structured, unstructured and semi-structured data
The Correct Answer and Explanation is :
The false statement is:
Big data can be stored and analysed using database management systems.
Explanation:
Big data refers to extremely large datasets that cannot be handled using traditional database management systems (DBMS) due to their volume, variety, and complexity. Let’s break down each statement for clarity:
- Big data can be stored and analyzed using database management systems:
This statement is false because traditional DBMS (such as relational databases) are not equipped to handle the sheer scale and diversity of big data. Traditional systems are limited by their ability to process large volumes of data efficiently. As a result, big data often requires specialized technologies like Hadoop or distributed storage systems, which can scale horizontally to accommodate the vast amounts of data. The volume, velocity, and variety of big data require tools such as Hadoop, NoSQL databases, and cloud-based solutions rather than conventional DBMS. - Big data includes datasets containing billions to trillions of records:
This statement is true. Big data typically involves datasets that are far too large to be processed by traditional data processing tools. These datasets might contain billions to trillions of records, far beyond what typical database systems can handle efficiently. - Big data can be stored and analyzed using a Hadoop cluster:
This statement is true. Hadoop is a popular framework for processing and storing large datasets. It allows for distributed storage and parallel processing, enabling the handling of massive volumes of data across clusters of machines. - Big data includes data sets containing structured, unstructured, and semi-structured data:
This statement is true. Big data is not limited to structured data (such as data in relational databases) but also includes unstructured data (like videos, images, and text) and semi-structured data (such as JSON or XML files). This diversity in data types is one of the defining characteristics of big data.
Thus, the correct false statement is the first one. Traditional DBMS are not suitable for managing big data effectively.
