What is NoSQL?

• • A type of SQL database

• • A relational database management system

• A non-relational database designed to handle unstructured data

• • A programming language

Which of the following is a key business driver for adopting NoSQL databases?

• • Need for complex joins

• • Fixed schema requirements

• • Scalability and flexibility to handle large volumes of unstructured data

• • Need for ACID compliance

NoSQL databases are often chosen over traditional relational databases because they:

• • Require less maintenance

• • Are better suited for distributed data storage

• • Use SQL for querying

• • Provide stronger consistency guarantees

Which NoSQL data architecture pattern is best suited for storing and retrieving simple key-value pairs?

• • Graph stores

• • Column family stores

• • Document stores

• • Key-value stores

Graph stores in NoSQL are most suitable for:

• • Storing large binary files

• • Managing relationships and connections between data points

• • Storing tabular data

• • Handling time-series data

Which of the following is an example of a Column family store?

• • MongoDB

• • Neo4j

• • Redis

• • Cassandra

Document stores in NoSQL databases are typically used for:

• • Handling transactions

• • Managing graph data

• • Storing and managing XML and JSON data

• • Storing key-value pairs only

In a case study where a company needs to handle high-velocity data ingestion and querying, which NoSQL database would be ideal?

• • MySQL

• • MongoDB

• • Neo4j

• • HBase

For a social media platform that needs to manage user connections and relationships, which NoSQL solution would be most appropriate?

• • Column family store

• • Document store

• • Key-value store

• • Graph store

Why are NoSQL databases often preferred for handling big data?

• • They provide strict ACID compliance

• • They excel at scaling horizontally across distributed systems

• • They are always cheaper than relational databases

• • They use a fixed schema for all data types
