Hex, a platform that allows users to use Python and SQL interchangeably, emphasizes the efficiency of using only SQL for data work. The text highlights four major problems that most SQL runners and IDEs do not solve effectively: organization, versioning, collaboration, and delivery. It argues that notebooks are an ideal tool for analytics due to their literate and self-documenting format, but existing solutions for SQL workflows in notebooks are often more trouble than they're worth. Hex addresses these challenges by providing features such as organization through Logic view, versioning with built-in versioning, collaboration with live editing and commenting, and delivery with the ability to turn SQL notebook layout into interactive data applications.
