Database
Architecture, Cont’d
– Free HL-7 parser and message generator,
Chameleon, from InterfaceWare of
Canada, when participating in Susan
Abernathy’s project in 2001-2002
– Other commercially available HL-7 parsers
such as Neotool are expected to work as
well
Contra Costa County Health Services, California

Architecture, Cont’d
– Cannot embed HL-7 parsers in our new,
dot-NET compiled IZ system because
neither in-house Neotool nor Chameleon
were compatible with dot-NET in 2001
– Wrapped in Microsoft web services
Advantages of web services
 Web services solved platform incompatibility
 Additional flexibility
