Description
SQL really is the language of Data Analysis.Learning to use SQL well, allows you to query the data in your organisation's databases so that you can answer the questions you have as a data and business professional. It is the "bread and butter" skill that data professionals have used for decades and it's as in-demand today as its ever been. For anyone wanting to move into the field of Data Analysis or those who have only worked with spreadsheets, or relied on others to query the data for them, this course will help you grasp the most useful SQL functionality and enable you to grow in your role.. even if you have no programming experience. Once you have that skill to query data in different ways and without reliance on others, you'll be able to find different ways to extract it and analyse it. Its only then that you gain insight into what organisational databases hold.This course comes with a financial database based upon an insurance claims model which you'll learn to query and build your skills with. All the lessons and exercises will be based on this database so you'll have the freedom to explore and investigate relationships in the data that other courses aren't usually able to offer. You'll install your very own database and will have access to all of the code used by the instructor, as well as the solution to exercises that you'll use to shore-up your skills.We'll take you through from the very basics, through to advanced functionality most commonly used in industry and not just the vanilla content you'll see in most other courses. You'll soon be a SQL hero. So what are you waiting for?
