I have downloaded the svn repository of Atunes using TortoiseSVN. I would like to transfer the logs of activity of the developers to a SQL database, preferably an Oracle one. Is there any software that can help me do this?
The command line SVN client can export the log to an XML file with the --xml option.
First you need to get complete repository of subversion. Tortoise svn do not have this option right now. I think you only checked out latest revision. You need to use other programs to get complete repository with all history for example: svk (http://svk.bestpractical.com/view/HomePage).
Subversion uses two backends.
Create your new repository Berkeley Db Based and get all history using a tool. After that since Berkeley DB (http://www.oracle.com/us/products/database/berkeley-db/index.html) Oracle supported one, you can migrate to Oracle.
But in my opinion this is all hard work. If all you need some statistics from subversion other tools exists for this purpose.
