types - MYSQL Database Structure - Storing Multiple Values -

-

i have questions regarding new database structure.

1. let's user can create recipe. each recipe have several ingredients. each ingredient have following 4 fields.

1. ingredients 2. quantity of ingredients 3. unit size of ingredients 4. prep method ingredients

i have been racking brain trying figure out how structure this. should create 4 rows , contain each 1 of inputs array , store in row belongs to? best way , efficient?

2. if have description field , directions field length of characters unknown, blob type best here?

thanks!

as ingredients can appear @ many recipes , different recipes can contain same ingredientes have n:n relation between recipes , ingredients.

on other hand, have called relation attributes try like:

  • recipes table: recipes
  • igredients table: ingredients
  • recipe - has - ingredient relation: stored in table: has_ingredient where: quantity, unit size, pre method fields , recipes primary key , ingredients primary key foreing keys.

consider following er diagram:
