# Schema Overview

The database schema is comprised of three tables: Visitors, Sessions and Pages. They are joined via `hem` and `session_id` respectively.&#x20;

## Database Tables

* The [Visitors Table](broken://pages/siHDCBicnEqs3yThx831) stores comprehensive information about individuals who have visited a website with the Distilled tag installed. B2B, B2C, and PTE records are consolidated in this table view.
* The [Sessions Table](broken://pages/ZsdaGbSwb7f7EUF5yMra) captures data pertaining to each visitor's session, including session duration. A session concludes when there has been no activity for 30 minutes. In the sessions table, you can find the column that provides the match type for a visitor record. This column is titled [file\_type](broken://pages/ZsdaGbSwb7f7EUF5yMra#table-structure) and will indicate whether a visitor is a B2B, B2C, or PTE record.
* The[ Pages Table ](broken://pages/ID1A40yrl4y6HRtk8rzn)records details about the pages viewed by individuals during their session.
* The [Buyer Intent Table](broken://pages/knsLajWbfdymACNso3te) records details about the modeled intent score of resolved website visitors.&#x20;
