What is Big Data?
Big data refers to extremely large data sets that may be analyzed computatically to reveal patterns, trends, and associations, especially relating to human behavior and interactions.
Can you explain Hadoop and its components?
Hadoop is an open-source platform that provides excellent data management provision. It is designed to scale up from a single server to thousands of machines. Its core components include Hadoop Common, HDFS, Hadoop YARN and Hadoop MapReduce.
What is MapReduce?
MapReduce is a programming model for processing large datasets with a parallel and distributed algorithm on a cluster. It consists of Map and Reduce functions.
Can you explain what is PIG in Hadoop?
Pig is a high-level scripting language that is used with Apache Hadoop. Pig enables data workers to write complex data transformations without knowing Java.
What do you understand by NoSQL databases?
NoSQL databases are non-relational databases that allow for stored data to be organized other than the simple tabular relations used relational databases.
What is ETL?
ETL stands for Extract, Transform, and Load, it's a process that involves extracting data from disparate sources, transforming it to fit business needs, then loading it into a database or data warehouse.
