This week's book giveaway is in the Agile and other Processes forum. We're giving away four copies of The Mikado Method and have Ola Ellnestam and Daniel Brolund on-line! See this thread for details.
Where may I find a list of all existing technologies to map data?
--> I can't follow anymore what is existing... and what are the advantage of these technos...
I would like to have a list with the cons and pro of each technologies (if possible with the differents versions).
I don't know of a comparison list anywhere - any such list is likely to be highly debatable, as any "technology A is better than technology B" tends to be. Your best bet is to google for ORM and have a read of what is said about the various choices you get back.
If you aren't currently using any ORM package, then I'd start by looking into JPA, which is the JEE standard for this. There are several implementations for it out there, including Hibernate, OpenJPA and EclipseLink.
