What you'll learn
SQL
Snowflake
Access and manage database
Switch from excel to database using SQL.
Requirements
No programming experience is needed, all the concepts will be taught from the basics and this course is purely for the beginners.
Description
This course is to learn SQL (Structured Query Language). Those who have been using excel to save their data and wants to move from excel to database and wants to understand how to interact with the database and how to write a SQL to get the data from the database, this course is for you. Most of the SQL concepts are shown with the reference to excel concepts which would make it easy to understand how things are work.Snowflake has been used in this course as a database. There are multiple reasons to use snowflake as a database, mainly because we get 200 USD worth free usage and also snowflake provides free trial for 30 days. Setup to start our database on snowflake is very quick and easy, it takes less than 5 mins to setup everything. And if we take the course with good dedication, we can finish this course well within 30 days of trial period. Even if you do not finish the course in 30 days, you always have a chance to create a another free trial account with snowflake and continue. We have tried our best to teach all the concepts properly and with good examples. We hope that this course will really help you to understand SQL and how to interact with the databases.
