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.
- An example business problem is introduced and formulated as a simple model.
- This initial model is executed from within Xpress Workbench, without any specific enhancements to include Xpress Insight.
- The model is published and executed within an Xpress Insight environment.
In later sections, we shall make some additional changes to the app.
- The model is annotated with metadata that provides Xpress Insight with further application configuration information.
- 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.
- A Tableau view is added, illustrating how to provide more complex visualizations of the underlying model data.
- 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.
