ServiceNow Application Development Fundamentals

Experienced ServiceNow system administrators who have at least one year of hands-on experience administering a ServiceNow instance. Experience writing both client-side and server-side JavaScript in ServiceNow is required.

A combination of lecture content and lab work helps attendees achieve the following:

• Design an application table: to extend or not to extend?
• Create and implement forms and views for a positive user experience
• Manage application business logic withscripts
• Control access to the application and its records
• Send notifications to stakeholders and collaborators
• Use Flow Designer to automate applications
• Integrate to ServiceNow and to public web services
• Use the Service Catalog to provide accessto applications
• Test the application manually and automatically
• Use the Application Repository to install/uninstall applications
