# Clipper Properties Guide (https://21notion.com/en/docs/properties/explore)

## Design Logic

The Explore Database is the unified database in the FLO.W Template for managing all "input-type content"—whether books, articles, videos, courses, or posts, they all converge here.

The core reasons for this design:

* **Unified Entry**: No need to switch between multiple Databases—all to-read/reading/completed content is in one place
* **Flexible Categorization**: Distinguish types through the "Content Format" Property, combined with view filtering—keeps data unified while allowing on-demand viewing
* **Connected Flow**: Reading is not an isolated behavior; it has relationships with Tasks, Projects, Notes, and Areas. These connections make knowledge truly flow
