Top 8 Data Science Tools Everyone Should Know

Do you ever wonder what the process and methodology behind revolutionary technologies such as artificial intelligence and machine learning are? The answer is Data Science. With the availability of various Data Science tools in the market, implementing AI has become easier and more scalable. In this article, we’ll discuss the best tools for Data Science in the market.

To get in-depth knowledge of Artificial Intelligence and Machine Learning, you can enroll for the live Machine Learning Course by Edureka with 24/7 support and lifetime access.

What Is Data Science?

Data Science is the art of drawing useful insights from data. To be more specific, it is the process of collecting, analyzing and modeling data to solve real-world problems.

Its applications vary from fraud detection and disease detection to recommendation engines and thus growing businesses. These wide ranges of applications and increased demand have led to the development of Data Science tools.

In the below section we’ll be discussing in-depth about the best Data Science tools in the market. But before we go there it is important that you understand that this blog is focused on the different Data Science tools and not the programming languages that can be used to implement Data Science. So, don’t expect there to be a war between which is better for Data Science, Python or R.

With that being said let’s dive straight into the Data Science tools.

Data Science Tools

The main feature of these tools is that you don’t have to use programming languages in order to implement Data Science. They come with pre-defined functions, algorithms, and a very user-friendly GUI. Hence, they can be used to build convoluted Machine Learning models without the use of a programming language.

Several start-ups and tech giants have been working on developing such user-friendly Data Science tools. However, since Data Science is a very vast process, it is often never enough to use one tool for the entire workflow.

Therefore, we’ll be looking at Data Science tools used for the different stages in a Data Science process, i.e.:

1. Data Storage
2. Exploratory Data Analysis
3. Data Modelling
4. Data Visualization

Data Science Tools For Data Storage

Apache Hadoop

Apache Hadoop is a free, open-source framework that can manage and store tons and tons of data. It provides distributed computing of massive data sets over a cluster of 1000s of computers. It is used for high-level computations and data processing.

Here’s a list of features of Apache Hadoop:

• Effectively scale large data on thousands of Hadoop clusters
• It uses the Hadoop Distributed File System (HDFS) for data storage which distributes massive amounts of data across several nodes for distributed, parallel computing
• Provides the functionality of other data processing modules, such as Hadoop MapReduce, Hadoop YARN, and so on

Microsoft HD Insights

Azure HDInsight is a cloud platform provided by Microsoft for the purpose of data storage, processing, and analytics. Enterprises such as Adobe, Jet, and Milliman use Azure HD Insights to process and manage massive amounts of data.

Here’s a list of features of Microsoft HD Insights:

• It provides full-fledged support to integrate with Apache Hadoop and Spark clusters for data processing
• Windows Azure Blob is the default storage system for Microsoft HD Insights. It can effectively manage the most sensitive data across thousands of nodes
• Provides Microsoft R Server that supports enterprise-scale R for performing statistical analysis and building strong Machine Learning models.
