A Data Scientist must be upgraded with the latest software and should know how to use them. As technology is changing and Big data has arrived, organizations are continuously evolving themselves to a higher level where with each day new software are being added to the organizations. The role of a Data Scientist encompasses the usage of various software and programming languages which he must master. This article describes the top 5 technical skills that a Data Scientist must master in order to be successful in his field.

Below are the Top 5 Technical skills Every Data Scientist Should know and master in 2019.  

  • R Programming

You will need the programming language R for statistical computing in Data Science. R makes good sense for its usage by Data scientists, statisticians, and Data analysts and so has its great popularity among the Data Scientist community. Nearly every of the organization today uses R due to the following salient features provided by it:

  1. R helps in the Visualization of your data. The Visualization of the Data provided by R through the is effective and appealing. The visualizations are clear and understandable.
  2. You do Statistical analysis of your data using R which is very easy to analyze. The statistical features provided by R is effective and diverse.

  • Apache Hadoop
The processing of Big data is a big concern for companies today. The big amount of data that is getting flooded through various sources in a company's database needed to be processed faster. Hadoop is the software for processing of this Big data only where with the help of distributed processing of large data sets across various clusters of computers is done using Hadoop. 
The execution of big data through Hadoop is faster which is also the reason why many of the companies today are using it.

  • Python
The inbuilt libraries of Python along with the features of object-oriented programming, structured programming, and functional programming makes it popular among the data science community. Programming in Python is simple and the features provided by it are very helpful for the data science professionals. 
 Pandas is the  Data Analysis Library of Python and is used for importing data from Excel spreadsheets and in processing datasets for data analysis which is useful in Data Science.
Also, Python is the most sought after programming languages and the majority of the companies today are mentioning it as the prominent skill in their data scientist job description.

  • SQL
SQL, or Structured Query Language, is used for managing datasets which are stored in relational database management systems. SQL is the language that almost every company uses for data science. Working on SQL is easy. There are many things which analysts and data Scientist do with SQL.
