The Horizon project views the management of machine-readable and human-like information with the same lens. In this sense, data management is one of the most important aspects of a Horizon space.

Tables let you normalize the data you collected. Spaces are not just about organizing tables and their schemas and underlying data, but about creating 'information hierarchies' for your project. The concept of 'information hierarchy' is where the regular 'machine-readable' normalization and repetition of the database meets your needs as a human being trying to make sense of an information environment.

'Information Hierarchies' are represented in a Space as a folder structure where you are storing both tables and notes and pages together within the same directory.

Towards this notion of a unified environment for storing both normalized data and the notes, text, and semantics of your project, Horizon provides the 'contents' directory where tables, sites, and folders all exist in a single wiki-like hierarchy, as seen below:
