Cornerstone of a modern service oriented architecture


Visual DataFlex Studio has a tool to use a Web Service class from dataflex code ( VDF Webservice Class ) The generated webservice client may use Call By Reference to return results.


Coding webservices

Usually , when coding webservices there are two approaches - "contract first" and "model first".

When using "Contract first" you usually get a WSDL file that your webservice must adhere to. When using "Code first" you typically write the code first and use a tool to generate the WDSL from the code.

The standard approach using Visual DataFlex is to use "code first".
