The accuracy, internal quality, and reliability of data is frequently referred to using the term ‘data integrity’. Without it, data is less valuable or even useless. This session takes a close look at what data integrity entails and how it can be enforced in multi-tier application architectures using distributed data sources and global transactions. The discussion will make clear which elements are required from any robust implementation of data oriented business rules aka data constraints and it will explain how most existing solutions are not as watertight as is frequently assumed. Steps for achieving reliable constraint enforcement are demonstrated.
The presentation I did last week for the JFall 2013 conference can be checked on SlideShare:
Last week’s JavaOne conference provided insights in the roadmap for the Java platform as well as in the current state of things in the Java community. The close relationship between Oracle and IBM concerning Java, the (continuing) lack of such a relationship with Google, the support from Microsoft for Java applications on its Azure cloud and the vibrant developer community – with over 200 different Java User Groups in many countries of the world.
There were no major surprises or stunning announcements. Java EE 7 (release in June) was celebrated, the progress of Java 8 SE explained as well as the progress on Java Embedded and ME. The availability of NetBeans 7.4 RC1 and JDK 8 Early Adopters release as well as the open sourcing of project Avatar probably were the only real news stories. The convergence of JavaFX and Java SE is almost complete; the upcoming alignment of Java SE Embedded and Java ME is the next big consolidation step that will lead to a unified platform where developers can use the same skills, development tools and APIs on EE, SE, SE Embedded and ME development. This means that anything that runs on ME will run on SE (Embedded) and EE – not necessarily the reverse More >
Last week – just when I was at the far end of a narrow internet connection – Oracle released JDeveloper 12c (12.1.2) along with ADF 12c and WebLogic 12c (12.1.2). Hot on the heels of Oracle Database 12c (12.1.2), which was released on June 25th – about two weeks earlier. The next figure gives an overview of recent new releases. It is clear that we are in a turbulent period right now – which also includes Java EE 7 (about a month ago) and the upcoming Java SE 8 release (next month). All in all there will be plenty to talk about at JavaOne and Oracle OpenWorld in September.
What is the significance of this ADF and JDeveloper release? What are the important themes and key features? Wow, that is a big question to ask and even more so to answer.
While the double entendre of ‘SUNday’ no longer exists, this first day is still an important day. To set the stage, manage expectations, build on the atmosphere and layout the roadmap (starting that sometimes not even subtle massaging of the minds). The keynote sessions are the key events that define scope and themes for the conference.
Java is very much on the move again. After the virtual stand still just before and for a while after Oracle took over (from) Sun, last year saw a dramatic increase in the Java movement. This year that thread continues. Not with many spectacular announcement, but with a solid pursuit of earlier roadmaps and an apparently good collaboration between vendors in the Java space. The one big elephant in the room – that is actually not in the room at JavaOne – is Google. Otherwise for example, Oracle staff happily shared the stage for this keynote session with IBM.
This year’s overall slogan for JavaOne is: Make the future Java.
It is very much an invitation from Oracle to help bring the Java platform forward. In many ways: ideas, feedback, testing, propagating, creating code, joining JSR committees etc. Oracle and other vendors More >
