I have just completed my first ever presentation on the Expertezed.com network – http://www.expertezed.com/ , a reprise from my session on Oracle OpenWorld 2012. This presentation includes a number of slides regarding 12c features, based on the session and slides from Tom Kyte (Top 12 new features) and my notes from the excellent session CON8511 – Temporal Database Capabilities with the Latest Generation of Database Technology that I attended during the conference.

The attraction of APEX has increased tremendously with the recent launch of the Oracle Cloud. APEX already supported departmental development and deployment of business applications with minimal involvement from the IT department (only a database needed be made available). Positioned as the ideal replacement for MS Access, APEX probably has managed better to capture the eye of developers and was used for enterprise application development at least as much as for the kind of tactical applications that Oracle strategically positioned it for.
With APEX as PaaS & DevaaS from the Oracle Cloud, a leap is made to a much higher level of business value. Now the IT department is not even needed to make infrastructure available with a database running on it. All the business needs is a credit card. And the business application that is developed, managed and used from the cloud through a standard browser can now just as easily be accessed by users from around the world as by users from the business department itself. As a bonus – the development of the APEX application is also done in the cloud – with no special demands on the location or the enterprise access privileges of the More >

Database 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:
On a recent project, I ran into a problem with an XML document, that had to be enclosed within another XML document, generated from a database query. The problem I ran into was the character encoding of the XMLElement function, which eventually was worked around with UPDATEXML.
In this blog post I would like to share with you several attempts to solve this problem, why they failed and the final solution to the problem.
Printing of official documents happened in a separate printing module. Whenever a document needed to be printed, an XML document was generated in a database query and sent to the printing module. Most of the data came from relational database tables, but pieces of standard text were supplied as XML documents by another party… and saved in our database in an XMLType column based on CLOB storage.
Our printing module expected to find these standard text XML documents within a tag in our generated XML document. Also both XML documents, our generated XML and the supplied XML, had different namespaces, this needed to maintained this way. The Oracle database version we were working with was 10.1.0.5.0.
In this post I will use a simplified version of the real XML More >
