I am not using Mere Mortals.NET (yet!), but I am using the business object in the Hentzenwerke book. Right now, I have the database connection string hard-coded in the BusinessObject base class. Is it a better idea to put this in the web.config file? That seems to be what I am reading so far as best practices. If so, then should I set the connection string from web.config in the BusinessObject constructor method?

public BusinessObject()
{
   this.strConnectionString = ConfigurationSettings.AppSettings("constring");
}
