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

Create a data object for the submitter, which contains name, address, and phone number.

Create a data object for the request type, which contains records for Type, Description, and Department.

The following table provides the credentials that you need to complete the challenge.

Role	User name	Password
Application Developer	author@mytown	pega123!

このチャレンジを完了するには、Pegaインスタンスを起動する必要があります。
