Become a Database Guru from Basic to Advance SQL PostgreSQL queries. Use SQL queries for Data analysis and Visualization

This course is designed for the beginners and freshers to gain knowledge on PostgreSQL and to use them in their projects/assignments. You will find different techniques to construct the SQL queries. The professionals who have zero knowledge or very less knowledge on SQL queries, will find this course extremely useful.

Learning SQL and PostgreSQL also helps you to become better data analyst and eventually would help you to get into the field of Data Science/ Data Analysis/ Data Visualization.

I will Guide you through a STEP by STEP approach on how to write SQL Queries. I will also explain about different ways to write very efficient SQL queries. I will first start with the installation of PostgreSQL database and PgAdmin 4 and then will install the North wind database model. I will then start writing some of the Simple SQL Queries and then slowly move towards filtering, grouping and slicing the data. Then, I will be working on more complicated topics like Joins, Operators, Inbuilt Functions and eventually by the end of the course you would be able to write complicated SQL queries.

You should be able to complete this course in a week time, if you dedicate 2 hours of your time daily and this journey will take you from zero to Hero.
