CQRS & Event sourcing combined results in elegant design pattern that offers many advantages over storing information regularly in a database. Imagine being able to know how a certain state was achieved instead of only knowing the end result. This is for instance useful if you need or want an audit trail on why an end state was recorded, or if you want redetermine an end state with additional data. The Axon framework is becoming more popular every day and it's one of the main frameworks to implement CQRS & Event Sourcing. The trainer has worked on two sizeable implementations and has given several talks on the subject at meetups. He will show, tell and help you understand how to work with Axon yourself.

Program:

• CQRS & event sourcing
• Introduction into Axon
• Aggregates
• Programming excercises.

Front end development can be tricky. Javascript is not a strict language, is not typesafe and allows you to create code that's not always reliable. Writing automated test can of course detect errors, but wouldn't it be better that the programming language that you use prevents them in the first place? Welcome to Elm. A language set up in a way that you as a developer are safeguarded from all kinds of common issues you will have in Javascript. Our trainer is a contributor to Still4M. A static code analyzer for Elm.

Java is a very effective programming language, with a huge community behind it. A language like Scala on the other hand implements functional programming principles that - for instance - allow developers to avoid null pointer exceptions. However, a commonly heard complaint is that it's hard to learn. Kotlin marries the two advantages without becoming a hard to learn language and its adoption is going really well. Google has even announced that Kotlin is the main language for developing Android applications. Kotlin is here to stay and this workshop is an excellent starting point to get started with it.

This training is focused on writing better code. The training is aimed at junior to medior software developers, and for everyone who regularly writes code (test automation engineers, for example).
This is a two day training. In the first day, the focus will be on the following subjects:

• Object Oriented Programming
• Clean code
• Unit testing
• Solid principles
• Patterns (if time allows, depending on the group)

The second day, the participants will work on a case study to build a REST API from scratch in Java with the Spring framework. The participants will get a certain degree of freedom to focus on aspects they want to improve in afterwards. This can be unit testing, integration testing, general software development or making CI pipelines. Basic knowledge of programming is required and basic knowledge of object oriented programming is helpful.
