How is the backend developed on Bitrix?

Question

1C-Bitrix

Good afternoon! My task is to create a website using Bitrix. I have some basics for creating sites, but on the instructions, the backend is a rather complex operation for building mat models based on the original table. How is a similar backend for Bitrix created? At the moment, the mat-part is written in R (very convenient language for data analysis). Is it possible to make R language and Bitrix friends???

Answer 1

The Bitrix backend is written in PHP, so there cannot be any inserts in the R language. But there may be http requests that in response will return the result of calculations for a script in R. Or the result of executing a console command (PHP eval function).
If for some reason this does not fit, then you will have to rewrite it all in PHP. To work with additional tables in Bitrix, it is customary to write modules containing a table description in the form of an ORM class (can be generated from the admin panel).
