Szenario
Hinweis: The framework of this challenge uses the view-based Constellation architecture of Pega Platform. To practice this challenge on the traditional UI-based architecture Theme Cosmos, see the Creating a data model version 8.7 challenge.
When creating an application, consider the data model. The data model defines how users store and retrieve the data in your application. In the MyTown application, you need the following data objects:
- A data object for a person that submits a request
- A data object with the details of the request type
Create a data object for the person submitting the request, which contains First name, Last name, Address, and Phone number.
Create a data object for the request type, which contains records for Type, Description, and Department.
Hinweis: A Request data object has been modeled for the MyTown311 application. The Request data object contains fields applicable to more than the business needs of the Service Request case type. As a best practice, the Request data object should be configured to be reusable across case types and applications.
The following table provides the credentials you need to complete the challenge.
| Role | User name | Password |
|---|---|---|
| Application Developer | author@mytown | pega123! |
Hinweis: Your practice environment may support the completion of multiple challenges. As a result, the configuration shown in the challenge walkthrough may not match your environment exactly.
