Re: Just tell me why ? so confuse...

Who told you that using a web service to access data was a bad idea? I
don't think that person knows what they are talking about.

Perhaps they meant that a web service class should not "directly" access a
database, but rather it should call another data layer class that gets the
data from the database and passes it back to the web service for the service
to pass back to the calling application.

Using web services to access data on remotes systems is possibly the most
common thing that people use web services for.
