When looking at the CSDM framework, ServiceNow uses the exact same underlying table (cmdb_ci_service) for both Business and Technical Services, meaning they share the same CI class.
Instead of creating separate database tables for each, ServiceNow relies entirely on the service_classification field to tell them apart and drive their unique roles in your environment. This keeps the backend architecture clean and ensures seamless integration with out-of-the-box features like Digital Portfolio Management—so you get all the operational distinctions you need without the headache of custom tables breaking future upgrades.
