OOW 2012: Data Visualizations with ADF DVT – continuous evolution demonstrated
0One of my favorite areas of ADF is Data Visualization. The rich, interactive and (un)usually attractive components that allow me to spice up an ADF application in a very easy straightforward way have a special appeal. We all know that pictures speak volumes. And that a plain table presents data while a carefully designed visualization presents information and perhaps even a call to action. One of my highlights during Oracle Open World 2012 was – not surprisingly – the presentation by the ADF DVT team – Katrina, Hugh and Jairam – together with Yiannis and Vangelis from PCS in Greece who built a wonderful ADF application for private investment management, with beautiful and very effective data visualizations all over the place.
The story of ADF DVT is one that started probably even before ADF with the BI Beans and before that perhaps even with Oracle Graphics. However, forget about all that history and look to the present and the future. No presentation of Fusion Applications is held without showing off its many data visualizations as a means to turn data into information and information into action. Drawing the user to exceptions, deadlines, alerts, patterns and items to act on is More >
JavaOne 2012: What’s new in Servlet3.1: An Overview
0Session at JavaOne come in various shapes. Some are visionary, high level and future oriented. Others are detailed and discuss practical, sometimes very fine grained topics. One of the sessions I attended was somewhere in between: future oriented yet pretty concrete at the same time. It was probably my favorite session at JavaOne this year: What’s new in Servlet3.1: An Overview by Shing Wai Cha and Rajiv Mordani. The passion of the presenters – their enthusiasm to explain the current development of the Servlet API and their ability to demonstrate some rather tough concepts were pivotal. Many presenters can take their style as an example they can learn from.
The Servlet 3.1 API is part of the JEE 7 edition- that is scheduled for complete release in April 2013. The Servlet Specification is largely complete, although some elements are still under discussion as became clear during this talk. The probably most important new requirement in Servlet 3.1 is the ability to do Web Socket interaction. Web Sockets is a relatively new communication protocol that runs over TCP/IP and goes beyond HTTP in several respects. Web Sockets support bi-directional interactions (open channels through More >
OOW 2012: The Very Very Latest in Database Development (CON4792)
0Database development in the Oracle Database is crucial for creating well balanced multi tier applications. This presentation describes a number of useful facilities and application architecture considerations around the database, taking into account some of the most recent insights.

JavaOne 2012: Strategy and Technical Keynote
0
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 >
JavaOne 2012: Thinking Through Java Enterprise Performance (BOF 4712)
0Performance of Enterprise Java Applications is a requirement and usually a challenge. Business requirements on systems can be stiff, successful systems can easily be overloaded and complex application architectures can add a burden too. Improving performance by tuning the application after it has been built seldomly renders huge improvements. By taking a step back – or even two – and regarding the application and the performance from a distance, it becomes possible to really design and architect for performance according to the ISYITF-method: it is staring you in the face. Order of magnitude improvements are attainable through logical reasoning and careful application of multi-tier architecture principles and JEE platform facilities.
This is the abstract for the session Thinking Through Java Enterprise Performance that I will be presenting on Tuesday October 2nd at JavaOne 2012 (BOF 4712 4:30 PM – 5:15 PM – Parc 55 – Cyril Magnin I.

OOW 2012: Questions to get answered during this conference
0The show of the year is around the corner: on Sunday it will all start again, the Oracle Open World conference. Tens of thousands of developers, architects, administrators, project managers, decision makers and others involved with Oracle products one way or another are gathering in and around San Francisco. AMIS will attend with an 8 person team. We will present, network, publish and investigate. As much as we bring our knowledge and experience to the conference, we also want to find out many things. A quick list of some of the questions that are on the top of my head to get answered during thus year’s conference:
CloudAfter last year’s announcements, we have not really seen any concrete cloud instances from Oracle. I hope to learn during this conference where exactly we stand and are headed with the Oracle Cloud – both the Application and the Platform Services. My focus will be on the latter in particular: what is the functionality and non-functionality offered by the various services – from Database Service to Web Services (PHP, Ruby and Python support) and Oracle Cloud Developer Services Hudson (for continuous integration, Git and GitHub for source control, wiki and tasks for More >
