In this blog, the category has been developed for those who are willing to master big data technology. It explains several tools and methodologies of performing operations on a large pool of data. The main focus of this section is to clarify the differences between the rivals to make it clear that which technology has to be used to meet different requirements. Apache Storm vs Apache Spark, Apache Hadoop vs Apache Storm, MapReduce vs Apache Spark, Hadoop vs SQL Performance, Business Intelligence vs BigData is some of the topics that have been covered here. While topics, like What, is Splunk, Uses Of Splunk, What is MapReduce, Hadoop Ecosystem and so on are also has been described.

The Necessity to learn Big Data

The five main reasons to study big data are:

1. The decisions that are driven by data are of competitive advantage

The organizations make use of big data to identify trends and detect patterns to predict the future. This way organizations know more than their competitors.

2. Big data is the foundation for Artificial Intelligence

The techniques and capacities required in big data organizations and artificial intelligence are similar. The organizations benefit greatly by building a sound big environment first and then set up artificial intelligence with big data as the base.

3. The demand for big data skills are high

With the current trends in big data, the requirement for big data professionals is rapidly growing. As a result, there are large increases in the salaries of the people working on big data.

4. There is growth in investments in big data everyday

Studies show that big data investments are growing year after year. The International Data Corporation (IDC) predicts that the data related hardware, software, and services are expected to grow at the rate of eleven percent by the year two thousand twenty.

5. Our horizon will broaden by studying big data

The fun investment of our time is studying big data. Our analytical and reasoning skills improve by studying big data because the domain of big data is full of puzzles to solve.

Applications of Big Data

The applications of big data are spread out in several areas and domains. Some of the domains and areas where big data is applicable are:

Healthcare domain
Manufacturing domain
Media and Entertainment domain
Internet of Things domain
Government sector
Cybersecurity and intelligence
Prediction and prevention of crime
Evaluation of pharmaceutical drug
Scientific Research
Forecasting of weather
Compliance of tax
Optimization of traffic

Example

The universities have an ocean of data and analytics and data visualizations have been used to draw patterns of data related to students' information in the universities.
