question about connection string

Hi all,

I am new to asp.net. A book I read teached the way to put connection string in web.config file. the file looks like this:
<configuration>
... other settings here ...
<appSettings>
<add key="DsnWroxBooksSql"
value="server=delmonte; database=WroxBooks; user id=sa; password=" />
... other settings here ...
</appSettings>
</configuration
I was just wondering what the user id "sa" and password ""is? I have seen these in many books. is it a system build in user name and password? Can I use my own user id and password instead? Also must I hardcode the password in web.config file? is there anyway I could get around it?

thank you!SA is the default administrator account for SQL Server. YOu use that when you are using mixed mode for authentication as opposed to windows.

Default password is blank, not recommended of course.

Yes you can create your own account and use it instead.
