"Human Resources Management System"?
I assume you want to use Moodle for training and record this on the HR system?
I do this with one of the Moodle sites I administer. I wrote a custom plugin. It's triggered upon course completion and that calls the HR system's web service API to register the change.
Like most integrations - the critical thing is what exactly do you need it to do?
Oh - please don't post (more or less) the same question in more than one forum. It's against our rules and dilutes your replies.
