Create an application

Create or open an application record.

Create: If creating an application directly, use Guided App Creator to create the application. Guided App Creater allows you to create tables from spreadsheets, roles, and security rules. Design options are also available.
Open: If developers do not have the admin role, the ServiceNow System Administrator needs to create the application and grant developers a delegated development role. Developers then use Studio to open the application for editing.

Note: The application scope and table name are sometimes referred to as the internal names for these objects and cannot be changed once they are created. However, the application name and table label can be changed. Application users see the internal names in the URL only. If possible, internal names should always be consistent with what the user sees.

Build the data model
Create tables and fields on the tables to support the application’s data model.
Secure data
Data security is one of the most important and overlooked aspects of creating an application. ServiceNow automatically configures access control for a new or selected role during the table creation process. Only users with the role can access the table to read, create, write, and delete.
Manage data
With the data model (tables and fields) created and security set up, add data into the application’s table(s).
