How are configuration settings stored for OmniStudio for Vlocity?

Configuration settings for OmniStudio in Vlocity are stored in Custom Settings. Custom Settings provide a way to create your own data sets which can be used to configure various features and components within Salesforce applications, including those for OmniStudio. This allows for a flexible way to specify and manage settings that may differ per environment or specific needs of the business process.

Using Custom Settings for configuration also enables easy access and updates, as these settings can be referenced within Apex code, Visualforce pages, and Lightning components. They can store user-specific settings or organization-level data, which is crucial for managing variations in user experience and functionality within OmniStudio projects.

The other choices, like standard objects or transaction logs, do not provide an effective mechanism for storing configuration settings due to their inherent purposes. Standard objects are used for widely-accepted business entities, while transaction logs serve as audit trails rather than configurable options for software behavior. The Salesforce Developer Console is a tool for development and debugging and does not store any application-specific configuration settings. Thus, Custom Settings are the appropriate choice for managing configuration in the context of OmniStudio.
