How to organize an algorithm for monitoring prices from different stores?

Question

Python

Hey!
Essence of the question:
Ultimately, it is necessary to compare the prices of a product from different stores.
That is, for example, I did a parsing of goods from different stores.
How to understand now that, for example, Apple 11 pro has three prices.
There are several such Apple 11 products in the database.
The name may change slightly, there are encodings somewhere, or some other signs.

Answer 1

No way, until the correlation rules are written or there is no preliminary mechanism where the user checks, changes or sets these identities and they are registered in the database.
This is usually done this way: if a new product arrives, the program looks for those products from other stores that match it by name and offer to confirm or refute the identity.
