mysql - Should there be data in a relationship table(Many-to-Many) or should it be in a separate table? -

-

डेटा को संबंध तालिका से अलग किया जाना चाहिए।

लघु पक्ष प्रश्न: यदि केवल 1 स्टॉक प्रति उपयोगकर्ता हो तो । क्या मुझे समग्र कुंजी को प्राथमिक कुंजी में user_stock तालिका में

उपयोग करना चाहिए?

यह एक रिलेशन टेबल नहीं होना चाहिए .. उपयोगकर्ता स्टॉक तालिका मास्टर टेबल के रूप में कार्य करेगी। उपयोगकर्ता कुंजी के रूप में यूजर आईडी और स्टॉक आईडी यूजर _id लेन-देन तालिका में अद्वितीय नहीं होगा
