Data layers
I have become rather interested in understanding the interplay between all these data access technologies that keep spouting around our feet. SDO and the ADO.NET Entity model appear to be charging towards a new level of abstraction that is well overdue.
ADO.NET appears to have the lead here based on being able to leverage the LINQ model to give a better programmer experience. However if invokedynamic and closures come to Java this might change rather quickly.
The kicker in this is usually not how high you can go but what you lose in the process of getting there. It will take a while to understand what has been traded but it’s an interesting area to watch never the less.
Busy
So it’s been a while…. Much happening to keep me busy; the big event has been the release of the Intel XML Library beta, see here if you fancy having a look. There are Java (JAXP dropin) and C++ versions to play with.
I also got the chance to write up some details of the processing model for Extreme Markup Languages 2007, the paper describes the model we use to process very large (1GByte size) documents.
