Three-Tier

A true three-tier reporting application, like the one shown in Figure 1-7, can be (but doesn’t have to be)

created using XML Report Web Services (covered in Chapter 6, “Creating XML Report Web Services”). A

Report Web Service is a Crystal Report that has been exposed as a Web Service to be used (or consumed)

by an application. Applications can connect to a Report Web Service, and the underlying report can be

viewed using either the Web or Windows Report Viewer. This provides all of the functionality (view,

drill-down, and export) found when integrating reports into a single or two-tier application, but with

the report running on a server behind the scenes, the lightest client resources are required for actually

viewing a report.
