Advanced SQL Queries

This projects highlight my knowledge of advance sql skills and techniques such as joins, transactions, views and stored procedure.

There are three datasets -

  • chicago_crime
  • chicago_socioeconomic_data
  • chicago_public_schools

We will load the .sql files located at Tables folder to create and populate three tables.

After that we will perform asked queries, solutions and questions can be found at Queries folder.

A Short description of each table :

Chicago_Crime
