🔥 DBMS Part-10: Converting ER Diagram into Tables & Relational Schema This video explains how an ER Diagram is converted into actual database tables. This is one of the most important DBMS topics for exams, interviews and real-world database design. 📌 Topics Covered: 1) Converting Entities into Tables Each entity in ER model becomes a table. Attributes become columns and primary key uniquely identifies records. 2) Converting Relationships ✔ One-to-One → Foreign key on either side ✔ One-to-Many → Foreign key on “Many” side ✔ Many-to-Many → Create a new mapping table 3) Composite Key In many-to-many relationships, combination of foreign keys forms a composite key. 4) Constraints Mapping ✔ Primary Key ✔ Foreign Key ✔ Unique ✔ Check ✔ Not Null 5) Weak Entity Conversion Weak entity uses: ✔ Its partial key ✔ Owner entity primary key 6) Attribute Conversion ✔ Simple → Direct column ✔ Composite → Split into sub-columns ✔ Derived → Not stored directly Real-world Example: Banking database with Customer, Account and Transaction tables. 🎯 This video is useful for: ✔ DBMS exams ✔ Viva & interviews ✔ Database design understanding ✔ SQL beginners 👉 Next Part: SQL Commands – DDL, DML, TCL & DCL Like, Share and Subscribe for the next DBMS video. ‪@AKSkillCraft‬ #dbms #erd #relationalmodel #database #cs #computereducation #bca #mca #btech #technology #computer #education #tech
