Database Design for Plants and Nutrients Inventory

Question

I am starting to design a relational MySQL database to keep a plants and nutrients inventory but I keep running in circles on how to design the tables.

I have various types of plants and various types of nutrients.

I am having trouble deciding how the tables are going to relate with each other, if I make some simple related tables and then make sub-tables to store specific information.

Answer 1

如果您不知道它们之间的关系，只需为带有ID的植物和营养素创建两个单独的表，然后再创建一个子表即可使用其ID或您想要的方式将具有多种营养素的一种植物关联起来，反之亦然。
