Question

Why Hadoop and Why not RDBMS for managing Big Data? Elaborate with suitable​

Answer 1

Answer:

• It is more flexible in storing, processing, and managing data than traditional RDBMS.
• Unlike traditional systems, Hadoop enables multiple analytical processes on the same data at the same time.
• It supports scalability very flexibly.
• In this both structured and unstructured data is processed.

Answer 2

Answer:

• RDBMS finds it challenging to handle such huge data volumes.
• Also, “big data” is generated at a very high velocity.
• RDBMS lacks in high velocity because it's designed for steady data retention rather than rapid growth.
• Even if RDBMS is used to handle and store “big data,” it will turn out to be very expensive.
