I am creating a application where a purchase manager purchases certain commodities on a given date. So, I have created a table with 2 columns (date and items).
Now, my problem is that purchase manager can purchase multiple items i.e; items keeps varying, say on 8th march- 10 items and on 9th march - 5 items. How should I create columns where items keep varying.
