# 📸 Instagram Clone Database (MySQL)
A **pure SQL** implementation of Instagram-like features, built entirely with **MySQL** — no backend frameworks, no ORMs.
This project demonstrates how to design, implement, and query a relational database for a social media platform **using only SQL**.
---
## 🚀 Features
- **User Accounts** (signup, profile data)
- **Posts & Media** (images, captions, timestamps)
- **Followers System** (follow/unfollow)
- **Likes & Comments**
- **Stories**
- **Hashtags & Search**
- **Notifications via Triggers**
- **Views** for feed summaries
- **Stored Procedures** for core actions:
- Create users, posts, comments
- Like posts
- Get user feed
- Explore popular posts
---
## 🗂️ Database Schema Overview
Below is the **ER Diagram** for the project:
```
\[ USERS ]───< \[ POSTS ] >───\[ MEDIA ]
│ │ │
│ │ └──< \[ COMMENTS ]
│ └──< \[ LIKES ]
│
└──< \[ FOLLOWERS ]
\[ HASHTAGS ]───< \[ POST\_HASHTAGS ]
\[ STORIES ]
\[ NOTIFICATIONS ]

## 🛠️ Setup Instructions
### 1️⃣ Install MySQL
Make sure you have **MySQL 8+** installed.
[Download MySQL](https://dev.mysql.com/downloads/)
### 2️⃣ Run the SQL Script
```bash
mysql -u root -p < instagram_clone_mysql.sql
````
### 3️⃣ Select the Database
```sql
USE instagram_clone;
```
### 4️⃣ Try the Stored Procedures
```sql
CALL get_user_feed(1, 10, 0);
CALL like_post(1, 3);
CALL create_comment(2, 3, 'Nice shot!');
```

## 🧠 How It Works
1. **Schema Design**
* All tables are normalized and indexed for scalability.
* Many-to-many relationships (hashtags, likes) handled via join tables.
2. **Business Logic in SQL**
* Core app logic is implemented via **stored procedures** and **triggers**.
* No ORM or server-side scripting — just SQL.
3. **Performance Considerations**
* Indexes on foreign keys & frequently searched columns.
* Views for quick feed summaries.
* Option to precompute feed (fan-out-on-write) or compute on demand (fan-out-on-read).
---
## 📚 Example Queries
Get the **latest feed for a user**:
```sql
CALL get_user_feed(1, 10, 0);
```
Find **popular posts**:
```sql
CALL explore_popular_posts(10);
```
---
## 💡 Future Improvements
* Private accounts & follow requests
* Pagination cursors (instead of OFFSET)
* Advanced search with FULLTEXT indexes
* Archiving old data for performance
