What allows everything to be contained in one application?

The correct choice highlights that extensibility is a key feature that enables everything to be contained within a single application. Extensibility in OneStream refers to the platform’s ability to be easily customized and adapted, which means additional functionalities or modules can be integrated seamlessly without disrupting the existing operations of the application. This flexibility allows organizations to tailor the OneStream platform to meet their specific business needs, bringing together various processes such as financial reporting, planning, and analytics into a unified system.

This means organizations can streamline their operations, reduce the need for multiple disparate systems, and enhance data integrity and accessibility, as all relevant functionalities exist within one cohesive application. Overall, extensibility is crucial for ensuring that an organization can build upon the core capabilities of OneStream while maintaining everything in one platform.
