Udemy courses in Java and SQL

Over the past two years I have taken a lot of really good training courses at Udemy. It's a great way to get instructor led training on a wide variety of technology topics. From that, there are two courses that rise to the top because they are very well done and provide a wealth of information to the QA engineer.

The first is a programming course. Since Java is the language of automation, I highly recommend:

Java Programming Masterclass for Software Developers by Tim Buchalka

You know you're in for a lot of information when the course is a staggering 80 hours of content. It covers the basics of Java, how to get it installed, picking an IDE, a quick overview of data types, and how to get your first programming running.

Tim then gets into the meatier topics of classes, objects, inheritance, constructors and encapsulation. And for each topic there are plenty of code examples, exercises and demos. There also lots of conversations about programming methodology to hold things together.

While not an automation course, it provides a wealth of information to develop and improve your code. I've learned a huge amount from this course and I don't consider myself to be a developer.

The second course on the list is:

The Complete SQL Bootcamp by Jose Portilla

To me, SQL is an umbrella term for many things. There is the language, the database itself, database theory, architecting, maintenance, and development (stored procedures).

That's not where I need to be. I'm not a SQL engineer, but writing a query is a huge benefit to the QA engineer. We can validate site information and provide dynamic data for Katalon scripts. This course focuses on building those kinds of queries.

It starts off with the basics of SQL, the SELECT statement then moves into COUNT, JOIN, ORDER BY, LIKE, WHERE, BETWEEN and GROUP BY.

For your own practice, it goes over the basics of installing and creating a database, setting up data types, and gives a solid foundation for starting with SQL – the language.

I am by no means an expert, but the topic is no longer a total mystery to me. As noted, I've been able to connect Katalon into our database and retrieve data. While I'm not the fastest at putting a query together, I have a far better understanding of what I'm doing.

As a matter of fact, I plan to retake this course during this slow period of the holidays as a refresher and to dig deeper into topics now that I have a better understanding.
