Automatically refresh using javascript every "X" minutes. [/quote]
You wouldn't use JS for that - just a simple pragma refresh.
Quote: But it's periodical check and I would like to refresh page immediately after change DB.
Then you definitely need to JS it.
But remember, both methods may be annoying for users, especially if they are in the middle of something - a text-copy, editing a field, or just reading the content, etc.
I'd go for a little notifier that reports if there is new information the user may be interested in, and offer them a link to refresh the page. This requires JS, of course, so it's out of my skillset.
