AI has taken over a lot of our mundane tasks and made life easier for us in the process. The credit for this goes to the insane amount of research and dedication put in by the researchers, data scientists and developers towards gathering, studying and reshaping the data. Not just the IT sector, but all sorts of industries have benefitted from these advancements. None of it would’ve been possible without the development and improvements in the tools for the job.

Top Data Science Tools to Learn in 2020

When I say “data science”, I am referring to the collection of tools that turn data into real-world actions. These include machine learning, database technologies, statistics, programming, and domain-specific technologies.

With the improvements in the existing tools and entry of newer ones into the Data Science scene, many tasks have become achievable, which were earlier either too intricate or unmanageable. The core idea behind these tools is to unite data analysis, machine learning, statistics and related concepts to make the most out of data. These tools are critical for anyone looking to dive into the world of Data Science and picking the right tools can make a world of difference.

Information is the oil of the 21st century, and analytics is the combustion engine.

● Apache Hadoop

Open source software for reliable, distributed, scalable computing.

Hadoop — Open source software for reliable, distributed, scalable computing(source)

Apache Hadoop
is an open-source software by Apache Software Foundation authorized under the Apache License 2.0. By using parallel processing across clusters of nodes, it facilitates solving complex computational problems and data-intensive tasks. Hadoop does this by splitting large files into chunks and sending it over to nodes with instructions. The components that help Hadoop achieve increased efficiency and smoother processing are:

● Hadoop Common offers standard libraries and functions for the subsystems

● Hadoop Distributed File System provides the filesystem and mechanism for splitting and distributing the chunks

● Hadoop YARN schedules the jobs and manages the clusters

● Hadoop MapReduce for handling the parallel processing

● Speed up disk-powered performance by up to 10 times per project

● Integrate with external apps and software solutions seamlessly

● SaS

Turn data into insights

Short for Statistical Analysis System, SAS is a statistical tool developed by SAS Institute. It is one of the oldest data analysis tools available. The latest stable build v9.4m6 was released back in November 2018. Key features offered by SAS are:

● Easy to learn with loads of available tutorials

● A well-packed suite of tools

● Simple yet powerful GUI

● Granular analysis of textual content

● Seamless and dedicated technical support

● Visually appealing reports

● Identification of spelling errors and grammar mistakes for a more accurate analysis

The goal is to turn data into information, and information into insight.
- Carly Fiorina

SAS allows you to mine, alter, manage and retrieve data from several areas. Paired with SQL, SAS becomes an extremely efficient tool for data access and analysis. SAS has grown into a suite of tools serving several purposes, some of these areas are:

● Data Mining

● Statistical Analysis

● Business Intelligence Applications

● Clinical Trial Analysis

● Econometrics & Time Series Analysis

● Tableau

Powerful and fastest growing data visualization tool

is a remarkable data visualization tool that was recently acquired by Salesforce, one of the leading enterprise CRMs in the world. Focussed on providing a clear representation of data in a short period, Tableau can assist in quicker decision-making. It does so by making use of online analytical processing cubes, cloud databases, spreadsheets and relational databases.

The convenient nature of Tableau lets you stay focussed on the statistics instead of worrying about setting it up. Getting started is as easy as dragging and dropping a dataset onto the application while setting up filters and customizing the dataset is a breeze.
  • Comprehensive end-to-end analytics
  • Advanced data calculations
  • Effortless content discoveries
  • A fully protected system that reduces security risks to the bare minimum
  • A responsive user interface that fits all types of devices and screen dimensions

An interesting thing to know —

● TensorFlow

When it comes to AI, DL and ML, TensorFlow is a name that you will hear one way or the other. Offered by Google, TensorFlow is a library that does it all, be it building and training models, deploying on diverse platforms such as computers, smartphones and servers, to achieving maximum potential with finite resources.

Using TensorFlow, you can create statistical models, data visualizations and get access to some of the best in class and widely used features for ML and DL. TensorFlow’s inclination towards Python makes it a powerful programming language to operate with numbers and data by storing, filtering and manipulating them for distributed numerical computations.

● DataRobot

Founded in 2012
, DataRobot is now termed as the enterprise-level solution for all your AI needs. It aims to automate the end-to-end process of building, deploying and maintaining your AI. DataRobot can get you started with a few simple clicks and get a lot done without requiring you to be a pro. DataRobot offers the following capabilities for your business needs:

● Automated ML

● Automated Time Series

● MLOps

● Paxata

These can be combined or used individually with other deployment options such as Cloud or On-Premises. For Data Scientists, this enables them to focus more on the problem at hand rather than working on setting things up.

● BigML

Start making data-driven decisions today.

was founded with one goal, to make building and sharing datasets and models easier for everyone, ultimately making Machine Learning easier. Aimed to offer powerful ML algorithms, with just one framework for reduced dependencies. BigML’s expertise includes the following areas:

● Classification

● Regression

● Time Series Forecasting

● Cluster Analysis

● Anomaly Detection

● Topic Modelling

BigML includes an easy-to-use GUI that allows for interactive visualization, making decision-making a breeze for Data Scientists. Support for REST APIs can get you up and running in no time. Ability to export models via JSON PML and PMML makes for a seamless transition from one platform to another. Support for on-premises and off-premises deployment is also available.

● Knime

ree and open-source data analytics, reporting and integration platform

is a multi-purpose tool that does data reporting and analytics while enabling easy integration of elements such as data mining and machine learning onto your data. KNIME’s intuitive GUI allows for easy extraction, transformation and loading of data with minimal programming knowledge. Enabling the creation of visual data pipelines to create models and interactive views, KNIME can work on large data volumes.

Part of Microsoft’s Office suite of tools, Excel for an average joe would be a simple spreadsheet management tool but, in the hands of power users such as Data Scientists, it becomes an extremely efficient tool. Excel is known for being a simple tool for newbies to get into but, once they figure out how powerful it is, they stay.

Excel presents data in such a way that makes decision-making at a glance effortless with its powerful data visualization style. The formulas offered by Excel act as the cherry on top as this transforms Excel from a mere number presenting application into something that can also process those huge numbers, be it concatenation, finding length, finding sum and average and hundreds more.


Data plays a determining role in today’s AI-enabled world, enabling Data Scientists to make impactful decisions. In the absence of capable data science tools, that task becomes painfully intricate. We’ve made it easier for you to get an insight into the tools available, regardless of your level of expertise. If you’re attracted to data science, you have a broad collection of tools to pick. While some of these tools are worthy of being called all-rounders, some cater to specific niches.

To eliminate problems of different kinds, I want to alert you to the fact this article represent just my personal opinion I want to share, and you possess every right to disagree with it.
