Building a Basic Xpress Insight App

This main section walks through the key steps in building an Xpress Insight app. They are typical of the stages through which all models progress as they are transformed into independent Xpress Insight apps.
  1. An example business problem is introduced and formulated as a simple model.
  2. This initial model is executed from within Xpress Workbench, without any specific enhancements to include Xpress Insight.
  3. Next, a set of changes are made to the model—These allow it to be published and executed within an Xpress Insight environment.
    • A standard Xpress Insight directory structure is created.
    • The model is annotated with metadata that provides Xpress Insight with further application configuration information.
    • The groundwork for a custom user-interface is prepared with the creation of a companion file, which describes some of the organizational features of a proposed user interface.
  4. The main user interface is built from a combination of VDL elements, introducing the techniques required to use familiar, industry-standard components like tables, forms and fields.
In later chapters, we shall extend this model:
  1. A Tableau view is added, illustrating how to provide more complex visualizations of the underlying model data.
  2. Finally, the app is enhanced by adding the capability to manipulate attached files from both the model and the user interface, together with the creation of a custom execution mode which offers opportunities to select and trigger model actions.
