Java - It is the oldest and most appropriate language for a Data Engineer.SQL has the ability to store, retrieve, manage and manipulate data, as well as extract performance metrics to guide Data Scientists in their processes.Īs a Data Engineer, the most popular programming languages are:.This is everything a Data Scientist wants and needs. Python has a larger developer community, with extensive libraries, very concise syntax, and portability.R, C++, and Java are still popular, however, Python and SQL are very popular due to their simpler coding abilities whilst producing the same results. The most popular languages used by Data Scientists are Python, and SQL, with R, C++ and Java after. SQL - will allow you to communicate with the databases easily.Īs a Data Scientist, you have a choice between various programming languages.Python - will allow you to analyse, manipulate, clean, and visualise data. With this being said, the best programming languages for a Data Analyst would be Python and/or SQL. So after seeing this online, you’re probably thinking - where do I go from here? Which one do I actually need for the role I’m interested in?Īs a Data Analyst, you will be responsible for scanning through the data, finding valuable information and providing reports or visualisations. If you were to Google, what are the top programming languages - you will see a mixture of these, and probably a few more: Research Scientist - in relation to data, they are responsible for researching, designing, and analysing information from investigations, experiments and trials. Machine Learning Engineer - responsible for building AI systems that consume large amounts of data and be able to generate and develop algorithms capable of learning and making future predictions. Let’s start by defining the popular data roles.ĭata Analyst - look through data and provide reports and visualisations which explain the data.ĭata Scientist - collects, cleans, analyses data, provides reports, visualisations and manipulates data to perform advanced data analysis.ĭata Engineer - responsible for setting up and maintaining the organization's data infrastructure, whilst ensuring that the data can undergo critical analysis and can perform and produce reports. This blog aims to give you a quick and simple understanding of what programming languages are required or essential for specific data roles.
