Tutorial 2: Modeling an Advanced Application

Use

In this tutorial, you model an application that retrieves details about a specified buyer and then displays a list of sales orders for that buyer. The runtime user can then display details about a specific order and the items that it contains.

Prerequisites

• You have met the prerequisites listed in Modeling Your First Application with Visual Composer .

• You have completed the previous tutorial ( Tutorial 1: Modeling a Simple Application ) or have a basic knowledge of Visual Composer.

Process

This tutorial consists of the following sections:

1. Creating the base model to retrieve buyer details

   

   In this application, users enter a buyer ID number to display selected information about the buyer from the database.

2. Adding a second data service to retrieve a list of sales orders for that buyer

   

   In this enhanced application, users enter a buyer ID number to display selected information about the buyer from the database, including a list of sales orders for that buyer.

3. Reusing the existing model in a new model that provides details for a specific sales order

   

   In this application, users enter a buyer ID number to display selected information about the buyer from the database. They can then select a specific sales order for the buyer and view information about the items in the sales order.
