If the arrow represents an association, then the "O" would probably be a "0" (zero) to indicate multiplicity or how many objects can be involved in the relationship. Usually you'd have another symbol at the other end such as a number or N or *. E.g. 0->1 or 0->N or 0->*. Junilu
Hi Junilu, Its not about "0", i know about multiplicity. Its about a "O" on the arrow located at the center of the arrow. <pre> O _______________></pre> i guess its something related to asynchronous, or time out related symbol. I have seen it long time back some where, but i don't remember the resource.

If you don't remember the resource, you may not remember the exact symbol . Isn't the Booch symbol <--O to indicate that an object is returned ? Or it may also figure a clock when you have a basic character set. W. [ March 15, 2002: Message edited by: Wilfried LAURENT ]
