  description: Stages serve as the data platform's entry point for data collection, where source files are securely stored, enabling subsequent transformations and dataset generation. Files can be uploaded directly into stages via the HTTP API or through connectors, which support automated and continuous synchronization with your source systems. Stages provide secure, persistent storage and act as an interface for importing and exporting data files within the platform. To improve data discoverability, comprehension, and quality for end users, the data platform offers datasets as the recommended abstraction for organizing and sharing data.
