How to write a python server for telegram bot for multiple users?

Question

Python

I am writing a telegram bot. Using the bot, you can place orders, which consists of three fields (delivery address, quantity, etc.). All data is sent in messages (not a callback). In the case when several users order at the same time, how can I distinguish between them, and know which order the information came from, and which field the information came from? The callback doesn't fit. Is it possible to create a table in sql, and enter the user ID there, and fill it?
