Jaroslaw Ratajski

Java Developer since 1999. I love programming since my first line of code I did on the C64 in Basic. I have 15 Years experience developing JEE software working for various companies and projects. Currently I am working for CSS Versicherung in Luzern. I do design, lead teams and provide coaching and training inside company. I like to present my experience in public (Wroclaw JUG, DevCrowd 2013, 33rdDegre, Geecon, Capgemini Tech Talks). I like to do shows - presenting the things just as they work – with live coding, demos and hacking. 

Lectures

In English Beyond NoSQL – Do Events / DROP DATABASE

Are You satisfied with JPA and Hibernate? Do You think there is nothing better than classic three tier architecture where all data is processed in so called database? Or maybe... it is just a waste of time and money and You just do not know the alternatives...


This is not going to be about NoSQL...
This is about making one step more – No DB. There will be event sourcing presented and Prevayler as persistence framework. There will be shown how to utilize all the power of the JVM and how fun programming of business applications can can be (again – hurray!). Finally, there will be discussed problems, limitations and possible further alternatives in NoDB area.
