#17 Hibernate Tutorial in Hindi | One-to-Many & Many-to-One Mapping | mappedBy, JoinTable, FetchType

Welcome back to CodeHunt’s Hibernate–JPA Tutorial Series! In this session, we continue Hibernate Mapping – Part 2, where we cover two of the most widely used relationships in real-world applications: One-to-Many and Many-to-One Mapping. This video explains everything clearly with diagrams, database flow, and practical code examples so you understand how Hibernate manages parent–child relationships internally. 🎯 What You’ll Learn in This Video ✅ 1. One-to-Many Mapping What is One-to-Many relationship? How parent holds a list of child records How Hibernate creates the foreign key table ✅ 2. Many-to-One Mapping How foreign key is maintained in Many-to-One Code explanation with table structure Complete clarity with diagrams ✅ 3. mappedBy Explained What is mappedBy? Why mappedBy is used only on the non-owning side How it prevents duplicate foreign keys One-to-Many (mappedBy) vs Many-to-One (owning side) Owning side = The side which contains the foreign key ✅ 4. FetchType: LAZY vs EAGER Default fetch type for One-to-Many and Many-to-One Why One-to-Many is always LAZY Why Many-to-One is EAGER by default 🧠 By the End of This Session, You Will Clearly Understand: Difference between One-to-Many and Many-to-One Which side owns the relationship How mappedBy prevents extra foreign keys & join tables How cascading and fetch types work with collections How to design parent–child entities in Hibernate Interview-level clarity for relationship mapping 👨‍💻 Perfect For: Students | Java Developers | Hibernate Beginners | Backend Engineers | JPA Learners | Interview Preparation 📩 Contact for Enrollment: 📞 Call / WhatsApp: 8088467640 📌 Watch the Hibernate 2.0 Series Here: 👉 🔗    • Hibernate JPA | Gamma Batch Live🔊   #java #hibernate #springboot #codehunt #saifsir #jpatutorial #javamapping #onetomany #manytoone #mappedby #fetchtype #hibernateinterview #backenddevelopment
