Jaroslaw Ratajski Java Developer since 1999.

I love programming since my first line of code I did on the C64in Basic.
I have 15 Years experience developing JEE software working for various companies and projects.
From JavaScript/CSS3 to Java/JEE/Scala /Akka and down to the CPU/GPU level.

Previously I worked for various companies and customers (such as Capgemini, Lufthansa). Now I work for CSS Versicherung in Luzern.

I like to do shows - presenting the things just as they work – with live coding, demos and hacking. So: expect everything.

Beyond NoSQL

DROP DATABASE and do Event-Sourcing with Prevayler

LOCATION: Luzern
KEYWORDS: Concept, Technology, Product, Hands-On

AGENDA:17:15 - 18:30h: Talk plus Q/A
Afterwards you are invited to a refreshment.

SPEAKER: Jarek Ratajski   COMPANY: CSS Versicherung
SLIDES: http://www.setblack.pl/vision/dropdb_jug/index.html

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.

LEVEL OF TALK: Intermediate
