essential for the data engineer. <a href=\"https:\/\/datascientest.com\/en\/sql-vs-nosql\">Mastery of SQL and NoSQL technologies<\/a> is imperative, and an integral part of daily work.<\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><strong>Development<\/strong> is an integral part of the Data Engineer&#8217;s job. The most commonly used languages are Python, R and <a href=\"https:\/\/datascientest.com\/en\/comparing-scala-and-python-choosing-the-right-language-for-your-projects*\">Scala<\/a>. However, his knowledge of development also enables him to quickly upgrade to languages he doesn&#8217;t necessarily master, such as Golang, Ruby or Perl, to name but a few.<\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><strong>Data warehousing.<\/strong> These are modern, mainly cloud-oriented technologies that enable data to be stored and accessed easily. The main players in data warehousing are Amazon with Redshift, and Microsoft with Azure <a href=\"https:\/\/datascientest.com\/en\/sql-learn-all-about-the-programming-language-for-databases\">SQL Database.<\/a><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><strong>But Google&#8217;s Big Query<\/strong> and <a href=\"https:\/\/datascientest.com\/en\/snowflake-training-master-the-1st-cloud-data-warehouse\">Snowflake are also technologies that may be in demand.<\/a><br \/>It may seem obvious, but a strong knowledge of Windows and Linux operating systems is essential.<\/li><li style=\"font-weight: 400;\" aria-level=\"1\">As data volumes can be very large, the Data Engineer needs to be proficient in analyzing them (and the associated tools). <a href=\"https:\/\/datascientest.com\/en\/hadoop-what-is-it\">Hadoop-based solutions<\/a>, such as Hive or HBase, are among the most sought-after tools, and therefore the most important to master.<\/li><li style=\"font-weight: 400;\" aria-level=\"1\">Skills in understanding Machine Learning algorithms. This is primarily the core business of <strong>Data Scientists,<\/strong> but their understanding (without entering into the same level of competence) is important for Data Engineers. This will enable them to have a good understanding of how their data will be used, but also to be able to act on these algorithms if necessary.<\/li><li style=\"font-weight: 400;\" aria-level=\"1\">Although it may still seem obvious, strong communication skills are essential. <strong>Data Engineers<\/strong> will have to collaborate and present results to colleagues or managers who do not have the necessary expertise to grasp the various analyses. The ability to communicate in layman&#8217;s terms and make oneself understood by one&#8217;s audience is very important, whether in person, or now increasingly remotely, via presentations or e-mails.<\/li><li style=\"font-weight: 400;\" aria-level=\"1\">Knowledge of the steps involved in putting data into production, particularly via <strong>APIs<\/strong>, is very important for the Data Engineer.<\/li><li style=\"font-weight: 400;\" aria-level=\"1\">Indeed, they will be required to write APIs to enable users and other services to perform actions on datasets and Machine Learning models.
