Hey folks! I'm working on a relational schema for restaurant menus and could really use some feedback to ensure I'm on the right track. I'm trying to avoid any structural issues that could cause problems down the line since I'm still learning about database modeling.
Here's a simplified version of my use case:
- Each restaurant can have multiple menus (I'll start with one for now).
- A menu is tied to just one restaurant.
- Menus consist of groups that contain items.
- Menu items can have multiple images, and images can be shared across different items. The menu also showcases a gallery at the top.
- I'm implementing a sort order for UI purposes.
- I plan to add allergen and dietary info (like vegan and gluten-free) in the future, and I'm not sure how to best incorporate that into my design.
Here's what I have so far for the schema:
- **business** table: Contains business details.
- **menu** table: Includes the menu's basic info tied to the business.
- **menu_group** table: Organizes items into groups, allowing for descriptions and sort order.
- **menu_item** table: Holds item details, including allergens and pricing options.
- **menu_media** table: Stores media links associated with the menu.
- **menu_item_media_map**: A join table for linking menu items to media.
What I need to know is whether this setup can scale effectively and how best to handle the addition of allergens. Should I create a separate table for allergens, use a join table, or just add another field in my menu_item table? Thanks for any insights!

Honestly, your setup seems a bit complex for the requirements. Most menu displays are just simple text, and you can handle a lot of the searching and sorting on the client side. I’d suggest simplifying your schema—maybe use JSONB columns to house most of the menu details. This would streamline data retrieval. Keep your business and menu tables, but consider pushing some of the other info into JSONB within the menu table.
I see what you're saying, but I'm worried that if I turn the menu into a JSON item now, it might complicate future migrations or expansions. If I need to scale up later, managing everything stored as JSON could get tricky.
