The structure of the online store catalog

Question

Database design

Hello. Need help designing an online store catalog structure.
There are several sections of the catalog. Each product has some enumerated characteristics (brand, season, etc.).
Moreover, each section uses different characteristics for the goods. Or the same characteristics, but with different lists.
For example:
section "Clothes" - characteristics: "Brand", "Season", "Sport".
section "Phones" - characteristics: "Brand", "Color", "Charging connector".
Moreover, the list of brands for both sections will be different.
Can you give me some ideas or a link where I can read about it?

Answer 1

Google the sources of any online stores and see how they do it.

Answer 2

What is the actual question? There are product groups, each group has its own properties.

Answer 3

The main thing is not to reinvent the wheel:
Yandex.Market - catalog structure (product categories)
Mobile phones - basic parameters of mobile phones (click on "advanced search →" - look on the right)
The list of brands is always stored for everyone alone (exceptions: separate clothing manufacturers, publishers and authors of books, car brands, etc.). The "Screen Diagonal" parameter is most often 1 for all devices where there is a screen.
* these conditions are relatively true, because depending on the specific CMS and type of store, all of the above may be difficult to implement and will require revision.
