This installment of the BackOffice® Developer's Guide focuses on user interface design in greater detail than did previous installments. To clarify this discussion, we distinguish the user interface of an application from the user-services tier. These topics focus on the appearance of the application and its usability—how a user navigates among screens or reads and posts data.
Designing the PT Application User-Services Tier contains topics that discuss how the design team created the user-services tier with tools and technologies such as Active Server Pages (ASP), HTML, scripting languages, and XML and XML-related technologies.
