[Orgmode] Is there any way to active the reminder of Org mode in Emacs?

[DigitalPig]

Hi there~

I am using Emacs 22.2 with Org Mode 5.23a. I am wondering if Org mode
have the same function as diary in Emacs. That is if you have some
events or appointment. Diary pop-ups a window indicating that. How can I
let Org to remind me the coming events as diary? Thanks!
