Data Science is related with extracting, manipulating, processing and generating predictions out of data. In order to perform these tasks, we need various statistical tools and programming languages. In this article, we are going to share some of the well known Data Science Tools used by Data Scientists to carry out their data operations. We will try to understand the main features of the tools, benefits they can provide.

Brief Introduction To Data Science

Data Science has emerged out as one of the most popular fields of computer world. Companies are hiring Data Scientists to help them gain insights about the market and to improve their products. Data Scientists work as decision makers and are largely responsible for analyzing and processing a large amount of unstructured and structured data. In order to do so, he requires various specially designed tools and programming languages for Data Science to perform the task in the way he wants. Data scientists uses these data science tools to analyze and generate predictions.

Top Data Science Tools

Here is the list of best data science tools that most of the data scientists used.

1. SAS

SAS is one of those data science tools which are specifically designed for heavy statistical operations. It is a closed source proprietary software that is used by large organizations to analyze data these days. SAS uses base SAS programming language which for performing statistical modeling. It is widely used by data science professionals and companies working on reliable commercial software. SAS offers numerous statistical libraries and tools that a Data Scientist can use for modeling and organizing their huge data. It is highly reliable and has strong support from the company that is why it is highly expensive and is only used by larger industries. Also, SAS pales in comparison with some modern open-source tools. SAS has several libraries and packages but dome are not available in the base pack and can require an expensive upgradation.

2. Apache Spark

Apache Spark

Apache Spark or simply Spark is an all-powerful tool with analytics engine and it is one of the most used Data Science tool around the globe. Spark is specifically designed to handle batch processing and Stream Processing. It comes with many APIs that facilitate Data Scientists to make repeated access to data for Machine Learning, Storage in SQL, etc. It is an improvement over Hadoop and can perform 100 times faster than MapReduce. Spark has many Machine Learning APIs that can help Data Scientists to make powerful predictions with the given data.

Spark does better than other Big Data Platforms in its ability to handle streaming data. This means that Spark can process real-time data as compared to other analytical tools that process only historical data in batches. Spark offers various APIs that are programmable in Python, Java, and R. But the most powerful conjunction of Spark is with Scala programming language which is based on Java Virtual Machine and is cross-platform in nature.

Spark is highly efficient in cluster management which makes it much better than Hadoop as the latter is only used for storage. It is this cluster management system that allows Spark to process application at a high speed.

3. BigML

BigML

It is another tool widely used by Data Science professionals. BigML provides a great and fully intractable, cloud-based GUI environment that you can use for processing Machine Learning Algorithms. It provides a standardized software using cloud computing for industry requirements. Through it, companies can use Machine Learning algorithms across various parts of their company. For example, it can use this one software across for sales forecasting, risk analytics, and product innovation. BigML specializes in predictive modeling. It uses a wide variety of Machine Learning algorithms like clustering, classification, time-series forecasting, etc.

BigML provides an easy to use web-interface using Rest APIs and you can create a free account or a premium account based on your data needs. It allows interactive visualizations of data and provides you with the ability to export visual charts on your mobile or IOT devices.

Furthermore, BigML comes with various automation methods that can help you to automate the tuning of hyperparameter models and even automate the workflow of reusable scripts.

4. D3.js

Well known “Javascript” is mainly used as a client-side scripting language. D3.js, a Javascript library allows you to make interactive and great visualizations on your web-browser. With several APIs of D3.js, you can use several functions to create dynamic visualization and analysis of data in your browser. Another powerful feature of D3.js is the usage of animated transitions. D3.js makes documents dynamic by allowing updates on the client side and actively using the change in data to reflect visualizations on the browser.

You can combine this with CSS to create illustrious and transitory visualizations that will help you to implement customized graphs on web-pages. Overall, it can be a very useful tool for Data Scientists who are working on IOT based devices that require client-side interaction for visualization and data processing.

5. MATLAB

Matlab Logo

MATLAB is a multi-paradigm numerical computing environment for processing mathematical information. It is a closed-source software that facilitates matrix functions, algorithmic implementation and statistical modeling of data. MATLAB is most widely used in several scientific disciplines.

In Data Science, MATLAB is used for simulating neural networks and fuzzy logic. Using the MATLAB graphics library, you can create powerful visualizations. MATLAB is also used in image and signal processing. This makes it a very versatile tool for Data Scientists as they can tackle all the problems, from data cleaning and analysis to more advanced Deep Learning algorithms.

Furthermore, MATLAB’s easy integration for enterprise applications and embedded systems make it an ideal Data Science tool. It also helps in automating various tasks ranging from extraction of data to re-use of scripts for decision making. However, it suffers from the limitation of being a closed-source proprietary software.

6. Excel

Microsoft Excel

Probably Excel the most widely used tool for Data Analysis. Microsoft developed Excel specially for spreadsheet calculations but today, it is also used for data processing, visualization, and complex calculations. Excel is a robust analytical tool for Data Science.

Excel comes with various predefined formulas, tables, filters etc. You can also create your own custom functions and formulas using Excel. Excel is not for calculating the huge amount of Data like other tools, but still an ideal choice for creating powerful data visualizations and spreadsheets. You can also connect SQL with Excel and can use it to manipulate and analyze your data. So many Data Scientists are using Excel for data manipulation as it provides an easy and intractable GUI environment to pre-process information easily.

7. ggplot2

ggplot2 is an advanced software for data visualization for the R programming language. The developers created this tool to replace the native graphics package of R language. It uses powerful commands to create great illustrious visualizations. It is the widely used library that Data Scientists use for creating appealing visualizations from analyzed data.
Ggplot2 is part of tidyverse, a package in R that is designed for Data Science. One way in which ggplot2 is much better than the rest of the data visualizations is aesthetics. With ggplot2, Data Scientists can create customized visualizations in order to engage in enhanced storytelling. Using ggplot2, you can annotate your data in visualizations, add text labels to data points and boost intractability of your graphs. You can also create various styles of maps such as choropleths, cartograms, hexbins, etc. It is the most used data science tool.

8. Tableau
