G'Day from Australia,

Welcome, this is a SQL course that I am sure you will complete and benefit substantially from. 

The course is aimed at Beginners to Intermediate levels.

It covers all the bases for you to get up to speed with writing SQL before you progress on to more advanced SQL for

transforming and analysing data.

I will explain everything step by step and in detail so you get to know SQL very well. 

The course uses SQLServer 2014 express (Later versions are compatible) , and we all know the popularity of SQL Server and the thousands of enterprises that use it.

All data are included (for download) in the course so that you can practice what I teach and more.

Hello and Welcome,

My name is Paul Scotchford and I am thrilled that you are reading this.

When I get reviews like this one "oh my goodness. I cracked an Interview using this course" then I know the course material is hitting the spot ...

NewsJust released - SQLServer 2019 Data Analytics & Tableau Data Visualisation , this is a deep dive for beginner Data Analysts looking to become highly proficient in SQL and data visualisation, in this course you cover everything and the display results in Tableau.

As well as my normal consulting work in business and government I teach here on Udemy, there are 3 very distinct technology specialisations I work within and these are QlikViewQlikSense and SQL Server for delivering Data Analytics and Visualisations and in my downtime I go out and fly as a private pilot (that's my passion too) .

I have also been flagged as a Top-responding instructor which means that your Q&A will typically be answered within 24 Hours. In addition my Qlik courses are now offered on Udemy For Business (UFB)  .

QlikView and QlikSense

Professionally I have been delivering QlikView  solutions to business and government users for the past 8 years and QlikSense since it first released in 2014. Qlik delivers these products to the market and is an industry leader in the BI and Analytics world.

SQL Server

I have been delivering data analytics with the SQL Server (Tech Stack) for more than 17 years as this technology (in my humble opinion) is the best Relational Database and Data Warehouse (Mart) product on the market and will continue to be well into the future.


Because of my passion and experience working with these technologies in the real-world you can be assured that you will be getting first class training from my courses here on Udemy.

I am super stoked and looking forward to sharing my ongoing experience and passion for data analytics with you. 

Looking forward to seeing you in one of my courses soon.

News: Coming in 2020 a highly detailed QlikSense course , stay tuned!

Stay safe and well , looking forward to you joining in the courses.

Kind Regards
