Method for determining a Utility based on city and zip

1. see if there is a municipal utility for the city
	select * from Utility where municity='$city';
	
2. if not, find the county based on zip
	select coname,percentInCounty from ZipCode where zip5='$zip';
	
	foreach county name returned, find the utility (not municipal!)
	{
		select utilid from UtilityCounty where coname='$coname';
		select * from Utility where utilid='$utilid' and municity is null;
	}
	return the utilities thus accumulated.

WSDL parts

types
 These define the names of the internal operations and the structure of
	the data to be passed back and forth

messages
	The public messages to be passed between client and server.  Elements from
	the types are placed in the <part name="body"> subelement of <message>
	
porttypes
	The assembly of messages into ordered transactions known as <operation>.
	Each <operation> can have <input> <output> and <fault> messages
	
bindings
	Bindings list the transport layer methods available.  In our example we 
	use the SOAP protocol with "document" binding, and HTTP transport
	
services
	A service points the way to a physical implementation of a binding and 
	porttype on a physical machine.  One includes a <documentation> tag here
	which will be displayed to a client as part of the discovery process
