Tableau is easy to use, with a dynamic dashboard with drag and drop features that make it easy for anyone to handle. With high security and a smart dashboard, you can easily share with the clients in seconds.


Apache Spark

Apache Spark is an integrated analytics engine to process Big Data. Apache Spark is a free, open-source tool that was specially designed for data scientists, developers, and researchers. It works well for batch and streaming data.

Apache Spark is easy to learn, and you can use it interactively from the Python, R, Scala, and SQL shells too. Plus, it can run on any platform such as Apache Mesos, Hadoop, standalone, or in the cloud.

Spark includes all the important libraries like SparkSQL (that is for SQL and structured data), MLlib (for Machine learning), and SparkStreaming (Live dataStream processing)


I am sure after reading this article, you must have got a good understanding of all the major data analytics tools. To move ahead in your data analytics career, you would need to invest quite a bit of money in getting these tools and most importantly your time to properly understand these tools.
