No, as in the article mentioned, there is so much configuration that you can do. It has it's own programming language, and nowadays a lot is processed in the backend. It helps a lot when implementing new things on top. It provides for you already an entity model, and you can easily add your own tables (which most customers do). Migration to a new schema is my favorite part that I miss when I develop in other systems. For everything there is a tool that grew many years and is really battle tested.
