mam employ counter and dept type both are non prime and have dependance in them
like india and d394 in first 2 rows both are transitive dependent
Thank you mam u explain everything in very easy manner. Really helps me a lot to know the basics of DBMS. 😊❤
4:28 You mean Transitive Dependency right? Transitive Dependency (used for 3NF) where X -> Y where both X & Y are non-prime attributes.
But Function Dependency is something else right? (used for 2NF) where if r1.x == r2.x, then r1.y == r2.y
I'm confused, please clarify?
mam you will add more videos in this playlist or not
Data of 1st table and 2nd table. Are they correct ? 🤔 How 283,300& 232 can come in EMP_DEPT
I think this table is violating 2NF because subset of candidate key i.e emp_id is functional dependent on non-prime attribute(Emp_country). please clarify on this.
If it is in 3NF it is automatically in 2NF !
