## Overview
This project involves a comprehensive analysis of Netflix's movies and TV shows data using SQL. The goal is to extract valuable insights and answer various business questions based on the dataset.
## Objectives
- Analyze the distribution of content types (movies vs TV shows).
- Identify the most common ratings for movies and TV shows.
- List and analyze content based on release years, countries, and durations.
- Explore and categorize content based on specific criteria and keywords.
## Schema
```sql
DROP TABLE IF EXISTS netflix;
CREATE TABLE netflix
(
show_id VARCHAR(5),
type VARCHAR(10),
title VARCHAR(250),
director VARCHAR(550),
casts VARCHAR(1050),
country VARCHAR(550),
date_added VARCHAR(55),
release_year INT,
rating VARCHAR(15),
duration VARCHAR(15),
listed_in VARCHAR(250),
description VARCHAR(550)
);
```
## Business Problems and Solutions
### 1. Count the Number of Movies vs TV Shows
```sql
select type, count(*)
from netflix
group by type;
```
### 2. Find the most common rating for movies and TV shows
```sql
SELECT type , rating as most_common_rating from
(
select type, rating , count(*),
rank() over(partition by type order by count(*) desc) as rank
from netflix
group by type , rating
)
where rank = 1;
```
### 3. List all movies released in a specific year (e.g., 2020)
```sql
select * from netflix
where type = 'Movie' and release_year = '2020';
```
### 4. Find the top 5 countries with the most content on Netflix
```sql
select country, count(show_id)
from netflix
group by country
order by 2 DESC
LIMIT 5;
```
### 5. Find all the movies/TV shows by director 'Rajiv Chilaka'!
```sql
SELECT *
FROM netflix
WHERE
director = 'Rajiv Chilaka';
```
### 6. Find each year and the average numbers of content release by India on netflix.
### return top 5 year with highest avg content release !
```sql
SELECT
country,
release_year,
COUNT(show_id) as total_release,
ROUND(
COUNT(show_id)::numeric/
(SELECT COUNT(show_id) FROM netflix WHERE country = 'India')::numeric * 100
,2
)
as avg_release
FROM netflix
WHERE country = 'India'
GROUP BY country, 2
ORDER BY avg_release DESC
LIMIT 5;
```
### 7. List all movies that are documentaries
```sql
SELECT * FROM netflix
WHERE listed_in LIKE '%Documentaries'
```
### 8. Find all content without a director
```sql
SELECT * FROM netflix
WHERE director IS NULL
```
### 9. Find how many movies actor 'Salman Khan' appeared in last 10 years!
```sql
SELECT * FROM netflix
WHERE
casts LIKE '%Salman Khan%'
AND
release_year > EXTRACT(YEAR FROM CURRENT_DATE) - 10
```
### 10. Find the top 10 actors who have appeared in the highest number of movies produced in India.
```sql
SELECT
UNNEST(STRING_TO_ARRAY(casts, ',')) as actor,
COUNT(*)
FROM netflix
WHERE country = 'India'
GROUP BY 1
ORDER BY 2 DESC
LIMIT 10
```
### 15. Categorize Content Based on the Presence of 'Kill' and 'Violence' Keywords and count

COUNT(*) AS content_count
FROM (
SELECT
*,
