Zomato Data Exploration and Analysis with SQL (SQL SERVER)

Most of us know that Zomato is an Indian multinational restaurant aggregator and food delivery company. The idea of analysing the Zomato_dataset is to get the overview of what actutally is happening in their business. Zomato Dataset consist of more than 9000 rows with columns such as Restaurants_id, Restaurants_name, City, Location, Cuisines and many more...

While Exploring Data with SQL, I was working on the following things...

1. Checked all the details of table such column name, data types and constraints
2. Checked for duplicate values in [RestaurantId] column
3. Removed unwanted columns from table
4. Merged 2 differnt tables and added the new column of Country_Name with the help of primary key as [CountryCode] column
5. Identitfied and corrected the mis-spelled city names
6. Counted the no.of restaurants by rolling count/moving count using windows functions
7. Checked min,max,avg data for votes, rating & currency column.
8. Created new category column for rating

After Data Exploration with SQL, I started working on Analysing the Data with SQL where I found insights such as...

1. According to this Zomato Dataset, 90.67% of data is related to restaurants listed in India followed by USA(4.45%).
2. Out of 15 Countries only 2 countries provides Online delivery options to their customers, to be precised only 28.01% of restaurants in India and 46.67% of restaurants in UAE provides online delivery options.
3. As this dataset contains data most related to India so i worked on gaining insights on Indian Restaurants.
