Hi , i work on a game, this game most read and write on a database on website , my question is how can i find some document about access , read and write on database ?
and can anybody help me for basically information ?
tnx
Unity does not offer any such thing.
But .NET does, as such look at Microsofts MSDN or go-mono 
But if it is within a webplayer, you won’t access databases normally but php layers inbetween as you don’t want global wildcard access to your database (that and half the database systems+ require unmanaged dlls / dylibs along the application to work and are thus standalone distribution only)
my database isn’t within on webplayer. look . we have tree thing…
1-a web program for manage user account. written with php or asp.
2-database (any compatible kind).
3-online game , this game most read ,write and edit account information on website.
i haven’t and preview about know how can i create a connection with database!
The easiest way to do this is generally to have a web front end to the database (implemented with PHP, say) and then use Unity’s WWW and WWWForm classes to access it. The server side highscores code on the Unify wiki is a good, complete example of how to do this.
