Initializing help system before first use

# Advanced Topics

This section covers several advanced Xpress Insight topics.
Covered Topics

- Inter-scenario Data Access
  Inter-scenario data access is a feature that allows an Xpress Insight scenario to use data from another Xpress Insight scenario anywhere else in the repository.
- Controlling Access to VDL, JavaScript and Tableau Views
  An app can optionally specify a list of authorities that the user must possess to access a view.
- Multiple Users and Authentication
  Xpress Insight implements a user authentication and authorization security system.
- Building Apps that use the Decision Tree Editor
  If the app you are building generates or imports FSML or FJDT decision trees, you can make it possible for your users to edit the trees as attachments.
- Custom Scenario Types
  In addition to the default SCENARIO type that cannot be disabled or removed, you can create and define additional custom scenario types in an app. The appearance of the scenario and the actions that can be performed on it can be individually configured for each scenario type, by editing the app companion file (cfile).
- Making REST Requests with the JavaScript API
  Developers may need to get data from the Insight server that is not available from any JavaScript API methods by calling one of the Insight Server REST endpoints.
