Correct option is D
Given Databases:
(A) Memcached: A distributed memory caching system designed to speed up dynamic web applications by alleviating database load.
(B) CouchDB: A NoSQL database that uses JSON to store data and JavaScript for querying.
(C) Infinite Graph: A graph database designed for complex relationships in big data.
Big Data Context:
All three databases,
Memcached,
CouchDB, and
Infinite Graph, play significant roles in handling large-scale data associated with big data. Let’s analyze their applicability.
Analysis of Options:
1.
Memcached (A):
· While Memcached is primarily used for caching, it is often integrated with big data systems to enhance performance by reducing database load.
·
Applicable to Big Data.
2.
CouchDB (B):
· A NoSQL database optimized for distributed environments, CouchDB is widely used for storing and retrieving big data efficiently.
·
Applicable to Big Data.
3.
Infinite Graph (C):
· A specialized graph database designed for big data scenarios where relationships and connectivity are critical, such as social networks or recommendation systems.
·
Applicable to Big Data.
Correct Answer:
All three options (A), (B), (C) are relevant in the context of big data. Thus, the correct option is:
(a) (A), (B) and (C) true.
Information Booster:
1.
