Aisha Bukar draws some comparisons:
MySQL and PostgreSQL are two of the most popular relational database systems in the world. Both are open-source, widely used in web and enterprise applications, and support structured data in tables.
Modern applications, however, often work with semi-structured data that doesn’t always neatly fit into tables with rows and columns. This type of data gets its name because it still has some organization but doesn’t follow a strict format.
JSON (JavaScript Object Notation) is a popular way to store and share this kind of data. It’s a text format easy for both people and computers to understand.
Read on to see what’s supported in each of these platforms, as well as strengths and limitations of using JSON in each.
