In your project, you write specifications. These are read by the runtime components (database, web client) and this specification fully defines their behavior. There is no project specific code, everything you can write in your data model is supported by the runtime components. You can look under the hood at that level, the runtimes are built in C(++) and TypeScript etc., but it's completely generic. In fact a lot of that codebase is generated.
