Hello my name is Kris. I'm here because I am passionate about helping non-techie people to overcome their fear of learning SQL.
Let Me Help you Get Started on the Right Foot!
I know what it is like to not know where to start or whether the time spent learning is worth the effort. That is why I am here to help you to:
Get started in an easy to follow step-by-step manner.
Use your time wisely so you focus on what is important to learn to get the most value from your time.
Answer your questions. Really! Just post a comment and I'll respond. I'm here to help.
It wasn't long ago that I was helping a colleague with some reporting. She didn't know where to start and soon got overwhelmed and lost as she didn't know SQL.
I felt really bad, as she was under pressure to get some summary information to her boss, the built-in reports were falling short, and to make them better would require her to know SQL. At that time that seemed impossible! It in dawned on me, it doesn't have to be that way.
Then I discovered a way for anyone with the desire to easily learn SQL. I worked with my co-worker, started to teach her what I learned and soon she was able to write reports and answer her boss' questions without getting stressed or ploughing hours into manipulating data in Excel.
It hasn't always been easy. Sometimes the information seems abstract or too conceptual. In this case I've found out that a visual explanation is best. I really like to use diag

I need application exercises!

By Oliver Weimar-Drese

Good basis for normalization, will try use it in production.

By Rishi Chowdhury

yes very good content in a nutshell

By William Fallon

Breaks are too long between sentences, slides could be a little more professional.

Other than that I'm learning what I need to, and I just increased the video speed to make it more engaging.

By Jose N

Great course overall, the explanation of third normal form leaves somewhat to be desired though, transitive is explained with an example and not a concise, simplified, definition, more examples would be useful for this last case also.

By MUSAH Abdulmumini. Y

It has the fundamental basic ingredient to make you understand using very simple and live examples.

It is engaging and commendable , excellent instructor,

Good course, probably best viewed a few times. A link to some more practice scenarios would be a nice to have.

By Jacob Zachry

Everything you need to know about normalization in 1 hr. Perfect course for just anyone just getting started in database design.

By Di Salau

Learning SQL database development and this is critical to good design

By Wayne Shackel

Outstanding course, it really helped me to finally understand "normalization". Thank you, I really appreciate it.

By John Dunn

"Database Normalization Simplified" was an excellent course. It is top of the class. The instructor clearly stated that Normalization is hard to understand. However, through learning and practice, it can be intuitive. At the conclusion the course, I felt confident that I could create and design simple databases up to Third Normal Form. Of course, I would need additional learning and practice using other aspects of data modeling and design.

Now that I have dispelled my fears that I am capable of designing and creating relational databases, I am eager to continue my journey. Therefore, I am hoping that Mr. Wenzel will create more courses in other areas, such as Relationships with an emphasis on at least employing two junction tables. The concept of Many to Many is not explored adequately by many providers. Combining "Database Normalization Simplified" with a full course on relationships would be an ideal complement to the other database design and modeling courses on Udemy. This course would be helpful, not only for emerging database designers but also for Excel data modeling.

In short, thank you, Mr. Wenzel, for helping me in moving forward with the confidence and insights that I can create tables where "all nonkey columns are dependent on the key, the whole key, and nothing but the key, so help me Codd!"
