JavaOne 2012: The Big Stories
4The show is over, the people are gone and the cleaning can start.
What do we take home from JavaOne 2012?
That depends on who you ask. Some people primarily will have taken goodies from the exhibition floors with them while other may have focused on less tangible goods and gone for inspiration and vision. After the heyday (2006/2007), some waning years and the robust recovery (2011) after an initially tentative turn around (2010) this year seems to have been one of consolidation and careful further evolution. Some choices have been made – not all of them popular but most apparently sensible and reliable because backed by commercial sense.
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 Big Stories
0The show is over, the visitors are on their way home. The process of digesting the announcements, roadmaps and rumors – confirmed or not – can proceed in full swing. What has become of last year’s plans, what are this year’s plans (for next year and beyond) and what has materialized in terms of Oracle’s product portfolio. For everyone, the answers to these questions and the conclusions will be somewhat different – depending on focus, expectations and requirements. However, some conclusions will be shared by most who attended Oracle Open World 2012.
Without a doubt, some of the important themes were and will be: cloud – and at respectable distance – the next generation of database technology (12c) and of engineered systems (Exa… X3-v2), of mobile availability of both standard applications (Fusion Applications and other Oracle Applications products) and custom Portals and applications (through ADF Mobile on iOS and Android)
Facts and OpinionsThe Facts may seem the easy part – since these are more or less objective – but as soon as interpretation and clarification enter the fray , the absoluteness of the facts is not assured. For example around availability: is the Oracle Cloud 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.
The official slide deck from this presentation at Oracle Open World 2012:
OOW 2012: Is PL/SQL still alive?
0Yesterday Bryn Llewellyn, Distinguished Product Manager, did a session called “PL/SQL Enhancements brought by the latest generation of database technology”. The room was packed. For the upcoming release of the Oracle 12c database the enhancements were broken into three areas:
- Improved PL/SQL and SQL interoperability
In the current version of the Oracle database you needed a Nested Table or Varray Type defined at schema level in order to be able to use it in the TABLE operator. This is no longer necessary, it can be a PL/SQL declared type. The types that can be used as bind variables has been extended: Boolean, Nested Tables can be used as bindvariable in Dynamic SQL. Subquery Factoring (the With clause if you will) can hold private functions, the use case presented for this: pretty print an integer in K, M, G, T. Using userdefined PL/SQL functions in a SQL statement is not advisable, but if you really need to there is a new pragma: PRAGMA UDF. With this pragma the statement is almost as fast as pure SQL.
- Security
A new step has been taken to continue on “least privileges”, meaning that the user only gets the privileges that are absolutely necessary. A Role can be granted to a
