As Big Data continues to grow in importance at Software as a Service (SaaS) companies, the field of Big Data analytics is a safe bet for any professional looking for a fulfilling, high-paying career.

If you’re considering starting or advancing your career in the field of Big Data and data science, we’ve described three popular programming languages you might want to learn to give that career move a boost: R, Python and Hadoop.  

Why Learn R?

A good data scientist is a passionate coder-slash-statistician, and there’s no better programming language for a statistician to learn than R. The standard among statistical programming languages, R is sometimes called the “golden child” of data science. It’s a popular skill among Big Data analysts, and data scientists skilled in R are sought after by some of the biggest brands, including Google, Facebook, Bank of America and the New York Times.
In addition, R’s commercial applications increase by the minute, and companies appreciate its versatility. If you’re intrigued and want to know why you should learn R, here are a few more reasons why you should add R to your skillset:

R is open-source and freely available. Unlike SAS or Matlab, you can freely install, use, update, clone, modify, redistribute and resell R. This saves companies money, but it also allows for easy upgrades, which is useful for a statistical programming language.
 
R is cross-platform compatible. R can be run on Windows, Mac OS X and Linux. It can also import data from Microsoft Excel, Microsoft Access, MySQL, SQLite, Oracle and other programs.

R is a powerful scripting language. As such, R can handle large, complex data sets. R is also the best language to use for heavy, resource intensive simulations and it can be used on high performance computer clusters.
 
R  has widespread acclaim. With an estimated 2 million users, R is one of the top programming languages of 2017.

R is highly flexible and evolved. Many new developments in statistics first appear as R packages. 
 
Publishers love R. R integrates easily with document preparation systems like LaTeX. That means statistical output and graphics from R can be embedded into word-processing documents.
  
R has a huge, vibrant community and resource bank
, with a global community of passionate users who regularly interact on discussion forums and attend conferences. In addition, about 2000 free libraries are available for your unlimited use, covering statistical areas of finance, cluster analysis, high performance computing and more. 

Why learn Python 

Python is another programming language recommended to people who want to enter the Big Data or data science fields. It is easier to learn than R, yet it is a high-level programming language is the preferred choice among web and game developers.

Read on for more reasons why Python should be on your learning list for 2017.

Python is easy to learn. Like Java, C and Perl, the basics of Python are easier for newbies to grasp. A programmer coding in Python writes less code owing to the language’s user-friendly features like code readability, simple syntax, and ease-of-implementation.
 
Python is easier to debug. Bugs are every programmer’s worst nightmare, which is why Python’s unique design lends itself well to programmers starting out in data science. Writing less code means it is easier to debug. Programs compiled in Python are less prone to issues than those written in some other languages.
 
Python is widely used. Like R, the Python programming language is used in a variety of software packages and industries. Python powers Google’s search engine, YouTube, DropBox, Reddit, Quora, Disqus and FriendFeed. NASA, IBM and Mozilla rely heavily on Python. As a skilled Python specialist, you might land a job at one of these big name companies.

Python is an object-oriented language. A strong grasp of the fundamentals will help you migrate to any other object-oriented language because you’ll only need to learn the syntax of the new language.
 
Python is open source. As an open-source programming language, Python is free, which makes it appealing to startups and smaller companies. It’s simplicity also makes it appealing to smaller teams.
 
Python is a high-performance language. Python has long been the language of choice for building business-critical yet fast applications.

Python works with Rasberry Pi. If you want to do some amazing things with Raspberry Pi, then you must learn Python. From amateurs to expert programmers, anyone can now build a real-world applications using Python.

Why learn Hadoop 

If you are planning to make it in the Big Data field, Hadoop is another programming language you should learn. If you’re wondering about Hadoop vs. Python, this information below might help.

Like R and Python, Hadoop is open-source. That makes Hadoop a flexible option. 
 
Hadoop is powerful. Hadoop is easily able to store and process huge amounts of data. Its sheer horsepower and capability have impressed many. Forrester says Hadoop has “…become a must-have for large enterprises, forming the cornerstone of any flexible future data platforms needed in the age of the customer.”

Hadoop is versatile. Although Hadoop is used for warehousing data, it’s also used for predictive analytics, data discovery and ETL. 

Hadoop offers opportunities in a wide range of roles.  Hadoop professionals can find work as Hadoop Architects, Hadoop Developers, Data Scientists or Hadoop Administrators. 
 
Hadoop pays well. Hadoop is one of the most sought-after skills in the Big Data market, and certified Hadoop developers can expect to take home nice paychecks. 
 
Hadoop has a healthy future. For any professional seeking a career in Big Data, Hadoop will be a required skillset at some point.
 
Hadoop usage is increasing at multinational corporations. Top companies like Dell, Amazon Web Services, IBM, Yahoo, Microsoft, Google, eBay and Oracle are relying on this programming language. 
 
The fields of Big Data and data science will only continue to grow in our increasingly data-driven world. Make sure your career keeps up with that growth, with online courses that will boost your knowledge and credibility. Simplilearn can help. Simplilearn offers courses in Big Data, data science, R, Python, Hadoop and more.
