Tell me, please, the main ways of storing dynamic parameters for goods in the database. Those. There are several parameters that may or may not be in different products. How to make it take up less space so that you can quickly and simply remove, add and delete them. We should not forget about the values of the parameters themselves. I think that this question is of interest to many, because product groups may be completely different for online stores, respectively. and parameters too. What decision do you think is close to the truth? (EAV, 1 parameter to 1 column, well, etc.).
And also so that they can be sorted and compared
