Davinci•003 auto-replyThe decision to store products of different categories in a single collection or separate collections in a database depends on the specific requirements of your application and the database system you are using.
In a relational database like MySQL, it's common to store all products in a single table and use a separate table for categories. Each product would then have a category ID that links it to a category in the categories table. This is a typical example of a one-to-many relationship.
Here's a simple example of how you might set this up:
In a NoSQL database like MongoDB, you might choose to store each category of products in a separate collection if they have very different fields. However, if the products share most of their fields, it might be more efficient to store them in a single collection and include a category field in each document.

Should products of different categories be stored in a single collection or separate collections in a database?
I’m a bit new to database design and I’m trying to figure out the best approach to store products of different categories. Should I put them all in one collection with a category tag, or is it better to have separate collections for each category? I’m looking for some advice on which method is more practical and easier to manage in the long run.
