Designing the PT Application Business-Services Tier

The Performance Tracking (PT) application user-services tier is a client to the business objects. The business processing is handled by the business-services tier. This tier consists of COM objects and ASP pages, which work together to deliver a localized user interface that provides data access.

As a three-tier application, the PT application uses business logic that resides in business-services tier COM objects. The stored procedures in the PT application's Microsoft® SQL Server™ 7.0 database, the Eval database, also contribute to the business services. Translating Tasks into Stored Procedures lists the tasks the stored procedures perform, and Stored Procedures for the PT Application contains a table that lists the stored procedures the application implements. The ASP pages instantiate components that provide data access and collect the localized HTML files for each application screen by locale.

• Using ASP in the PT Application provides information about the localized and nonlocalized ASP pages this application needs to display the user interface and access the Eval database.
• Components in the PT Application describes the custom components that are reused from previous scenarios or designed for the PT application. This topic also includes a list of the standard objects and object models from the Microsoft technologies the application uses.
