OWB, web services and the database
By Jean-Pierre Dijcks on May 27, 2008
Since we get this question quite often, lets go back into this a little more. What is the story with OWB (or better the database) and web services? Well, you have all the tools and mechanisms around to simply hook it all together. What is all? Anything that speaks web services can speak to the database, and you can hook your DB processes (e.g. OWB mappings, OWB process flows etc) together with the Middleware frameworks like BPEL. You don't need any other tools to anything, just leverage what you have in the database.
How? Here are the details, excellently written out by Kuassi Mensah who is an expert in this at Oracle. There have been enhancements in Oracle Database 11g, but if you are on 10g this should be extremely helpful.
