Although many data scientists tend to incline to Python and R for writing programs for managing and processing data, Java is still a highly scalable programing language. It makes it easier to scale up or down and provides excellent load balancing features. What’s more, many key frameworks crucial in the field of Big Data, for example, Apache Spark, run on the JVM (Java Virtual Machine).

Julia

Julia is yet another open-source programing language used for numerical computing, machine learning, and other types of data science applications. It was created with a specific idea in mind – to be that one language addressing all possible needs. That said, Julia is a mix of high-level dynamic language and performance comparable to statically typed languages like Java and C. And, an in-built option defines data types in programs, not the users.

JavaScript

Once again, data scientists are expected to learn one of either Python or R. However, learning JavaScript too will undoubtedly prove valuable if you want to specialize in data visualization or need to use a product built using JavaScript or some of the related technologies. Also, the machine learning capabilities of JavaScript are advancing quite rapidly. Hence, mastering this programing language would be an excellent addition to your CV.

Software Technologies

Apache Spark

Apache Spark is an open-source data processing and analytics engine suitable for rapidly handling vast amounts of data. Thanks to its speed, this technology is great for continuous intelligence applications powered by near-real-time data processing. Furthermore, it is suited for extract, transform, and load uses and other SQL batch tasks.

Jupyter

Jupyter Notebook is another open-source web application enabling interaction among data scientists, engineers, mathematicians, etc. The tool is used to create, edit, and share code, text, images, and other information. Jupyter can add code, computations, comments, visuals, and media representations to a document that can be shared with others.

D3.js

D3.js, also known as D3 (Data-Driven Documents), is a JavaScript library for creating data visualizations in a web browser. It uses HTML, Scalable Vector Graphics, and CSS instead of having its graphical vocabulary. The tool is helpful for designing numerous kinds of data visualizations and supports interaction, animation, annotation, and quantitative analysis.

Pandas

Pandas is another popular Python library usually used for data analysis and manipulation. It’s composed of two primary structures: the Series (one-dimensional array) and the DataFrame (two-dimensional structure). Moreover, Pandas features in-built data visualization capabilities and exploratory data analysis functions and supports other file formats and languages.

TensorFlow

Here’s one developed by Google and famous for implementing deep learning neural networks. As the name suggests, TensorFlow takes inputs in the form of tensors and then uses a graph structure to flow data through computational operations determined by developers. And it provides an eager execution programming environment for running operations without graphs.

Tableau

Last but not least, Tableau is one of the most popular tools used by data scientists and business intelligence professionals. It is a data visualization tool enabling users to create insightful and impactful visuals interactively and creatively. Its use goes beyond creating traditional graphs and charts.
