Hi Nicolas, glad to meet you here) Sorry, I just add some information for Hassan and maybe also for another users, cause we had a similar need.
Hassan, if you mean your custom database (not jira one) you are able to add information into DB but you also should be advanced in a server part (Linux, Windows). All you need is post-function with a specific event which provides for the listener required information. But it is strongly not recomended to add information into own jira tables.
p.s. I have just seen the date of the issue) Let it be here, because answer is already typed)
