Code (SQL, Python, Node.JS)
Structured Query Language (SQL) is a standard computer language for relational databases and for performing various data operations. The software is coded to query, join, merge, update, and modify data. As a relational data system, it is comprised of a set of tables with columns and rows that contain data. As the original code for databases, SQL excels at accessing and organizing data, is relatively easy to learn, and is thus almost common knowledge among coders.
Python is a general purpose, high-level coding language that has long been used to develop software on the web and in apps; in recent years, however, it has found increasing popularity among professionals who work with data. Python was designed to empower its users, emphasizes code readability, and leverages syntax that allows programmers to accomplish tasks in fewer lines of code than prior languages. Python users tout its use due to its easiness to learn, the accessibility of the language, its expansive library of open source data tools and testing instruments.
