Oracle User Group Norway - Spring Seminar The OUGs are not the typical place for Java developers or community managers (namely me) to be. But OUGN has been working hard to build out a decent Java track with very good speakers, and it was a chance to see how the broader Oracle community is working together when it comes to Java. Also, I was in the neighborhood, more or less, and had never been on...

But, I got to see first-hand if they...

Introduction to Class Diagram In any project's planning phase, the programmer should describe the behaviour of the different objects that are required to satisfy business use cases.
