This question has been asked many times in the past in the forums, a quick search will yield many of those.
This article should also explain things pretty well - http://onlinehelp.tableau.com/current/pro/desktop/en-us/help.htm#multiple_connections.html#joinvsblend

thank you for replay.
i am asking about blending vs cross database join option.i don't have 10v. there is any differences.
Thank you once again
The article specifically discusses the differences between blending and joining.
This article discusses joins within a database, not cross-database joins done by Tableau. Completely different animals from a technical perspective.'
totally agree @Davidpetranek
Technically different, yes. Conceptually this article still applies though whether the join is cross database or within the same.
