Using the data load editor

This section describes how to use the data load editor to create or edit a data load script that can be used to load your data model into the app.

The data load script connects an app to a data source and loads data from the data source into the app. When you have loaded the data it is available to the app for analysis. When you want to create, edit and run a data load script you use the data load editor.

A script can be typed manually, or generated automatically. Complex script statements must, at least partially, be entered manually.
