Application Model Overview : How the Files Work Together

How the Files Work Together
In an ActiveGrid Application, the Page Flow orchestrates the flow of the application. The Page Flow knows what operations the application must perform when a user clicks a button or link, and which Page to display next. The Page Flow relies on the Service Definition to maintain specifications of all operations available to the application. These operations might be defined in web services external to the application, they might be locally-defined code or other operations. Similarly, the Page Flow relies on the Data Models to maintain a definition of the connection to each database, along with a logical representation of the data in that database.
The following figure loosely illustrates the roles of the various files within the application. The Page Flow coordinates the flow of the application and determines which Page to display in the client browser. The Data Models and Service Definitions provide a consistent application interface to the wide variety of data and operations that the application can access internally (custom code services, Pages) as well as externally (in web services and databases).
