In the previous article, we have read what Big Data is. As traditional analytics and Business Intelligence solutions, Data mining and analytics also help find the hidden patterns, correlations, raw data and the other beneficial business data. Big data is all about 3 V’s of data i.e Variety, Volume and Velocity of Data. Here Volume applies to the total amount of data, Variety applies to a number of types of Data and Velocity applies to the speed at which data streams.

What are the tools used in Big Data?
Apache Hadoop
Hadoop is an open source software framework originally incepted in 2006. The main purpose of Hadoop is to handle a large number of datasets. It is built with two main segments.
- Hadoop Distributed File System (HDFS) and
- MapReduce. HDFS is the storage constituent of Hadoop.
Hadoop stores data by dividing files into large blocks and scattering it across connections. MapReduce is the processing engine of Hadoop. Hadoop operates data by delivering code to nodes to process in correspondence. If you want to learn Hadoop for Big Data, check out the link Here
Apache Spark
Apache Spark is quickly emerging as a data analytics tool. It is an open source framework used for cluster computing. Spark is commonly used as an option to Hadoop’s MapReduce as it is capable of analyzing data up to 100 times faster for certain applications. Some of the common use cases of Apache Spark include streaming data, machine learning and interactive analysis. If you want to learn Spark for Big data, click here
Apache Hive
Apache Hive is a SQL-on-Hadoop data processing engine. Apache Hive excels at batch processing of ETL jobs and SQL queries. Hive employs a query language called HiveQL. If you want to learn Hive for Big data, click here
NoSQL Databases
NoSQL databases have great demand these days. These are not bound by traditional schema models allowing them to collect unstructured datasets. There are some of the databases like MongoDB, Cassandra, and HBase which have a lot of flexibility. That is the main reason why it has been a popular option for big data analysis.
However, for the Big Data Analysts, knowledge of these concepts is a must. If you want to learn the complete package of Big Data, head over to Digital Nest. It renders complete spectrum of courses for the students, IT professionals, and corporates to excel in the Big Data field.
