The Workflow Layer (WFL) component converts ADO Recordsets it receives from the Business Logic Layer (BLL) component into XML data. In the case of browser not supporting XML, the XML is transformed into HTML on the server. In the case of client who supports XML, the XML is passed to an Internet Explorer 5 client and parsed there.

The Workflow API is implemented as a COM component, and as Active Server Pages (ASP) script. EPM Workflow Layer (WFL) component will be a COM component written in Microsoft Visual Basic.

Server-side ASP scripts will use the ASP object model, WFL component, and style sheets to implement Workflow methods.
