Display
-Business Rules execute their logic when a form loads and a record is loaded from the database -Processed when a user requests a record form -Primary objective is to use a shared scratchpad object, g_scratchpad, which is also sent to the client as part of the form.
Start from an existing service
-Convert an existing service to an application if service creator is active -You may want to convert successful services into full application to utilize application features like contextual security, data or UI Policies, UI actions, and auditing
Start from global
-Create an application in the global scope -Required role: admin -Set the system property glide.app.creator.global to true
Create a custom application
-Create an application with UI and data elements -Good for applications that require UI elements and tables
Start from scratch
-Create an empty application -Good for application that only use one configuration record, such as workflow or script-based application
Start from a template
-Create service management application -Good for applications that need to track the status of requests or task-driven records
Captured in Update Set
-Customization -Tables & Fields -Reports -Workflows -Forms
Good fit for ServiceNow
-Data can be modeled in a relational database -Extensive use of forms to interact with data -Needs reporting -Needs workflow to manage processes
Bad fit for ServiceNow
-Data is unstructured such as audio or video -Requires "as-is" use of low level programmatic libraries -Multiplayer games or apps that need a game engine -No process flow through application
Not Captured in Update set
-Data, New Records -Configuration Items -Schedules -Users -Groups
ServiceNow Best Practices for Update Sets
-Do not delete update sets, if an update set is deleted, any updated record maybe overwritten in the next update -Do not include the system_id field from the ldap_server_config record in an update set, this points to the wrong system_id for the target instance and does not work -Do not back out the Default update set, causes damage to the system -Never change the Update Set field value in a Customer Update record -Do not mark an update set as Complete until it is ready to migrate. Once complete, do not change it back to "In progress". -Do not manually merge updates into an update set, always use the Merge Update Set module -If a committed update set has a problem in the test instance, build the fix in another update set in the development instance -Always preview an update set before committing it -Set completed update set on the production instance to "Ignore" -Keep a to-do list of manual changes and data loads that need to be completed after an update set is applied -Do not make too many changes at one time, verify that the correct changes have been made incrementally
Operations
-Import from Source Control -Link to Source Control -Edit Repository Configuration -Apply Remote Changes -Commit Changes -Stash Local Changes -Switch Branch -Create Branch -Create Tag -Manage Stashes -Create Repository: -Create credentials: -Grant Access to Repository
Client-side debugging & UI Policies debugging

Cross-scope privilege record
-Runtime access tracking uses __________________________ to determine which script operations and targets the system allows to run -System creates this when: Runtime Tracking is set to "Tracking" or "Enforcing"
Application Creation options
-Start from scratch -Create a custom application -Start from a template -Start from an existing service -Start from global
Code Review Workflow
