Not exactly. For example, request "/favicon.ico":

location / {
alias /data/www;
}

will result in opening "/data/wwwfavicon.ico", while:

location / {
root /data/www;
}

will return "/data/www/favicon.ico".

But,

location / {
alias /data/www/;
}

will work the same way as

location / {
root /data/www;
}

or

location / {
root /data/www/;
}
