Equivalence of Functional Dependencies | Solved Example 3 | Functional Dependency | RDBMS

## **Topic:** *Equivalence of Functional Dependencies – Solved Example 3*

In this video, we solve **Example 3** on checking the equivalence of two sets of Functional Dependencies using a clear and structured method.

You will learn:

* What it means for two FD sets to be **equivalent**
* Step-by-step process to verify:

* Whether F₁ implies F₂
* Whether F₂ implies F₁
* How to compute **Attribute Closure (X⁺)** accurately
* How to detect missing, extra, or redundant dependencies
* Exam-oriented strategy to solve equivalence problems efficiently

This example strengthens your understanding of:

* Functional Dependency
* Attribute Closure
* Redundant Functional Dependencies
* Minimal Cover
* Normalization (2NF, 3NF, BCNF)

Equivalence-based questions are frequently asked in:

* **University examinations**
* Competitive exams (GATE basics)
* Technical interviews
* Advanced database design problems

This session focuses on developing a **strong analytical approach**, helping you confidently handle equivalence and implication questions in DBMS.
