## Introduction to Data Inventory [#introduction-to-data-inventory]

Your Data Inventory is the base truth of all data in your company: data systems, the datapoints inside them, and metadata about what each <GlossaryTerm id="datapoint">datapoint</GlossaryTerm> represents. This is the system-level reality, and it powers other features across the Transcend platform, from keeping your ROPA live-updated to generating Consent rules for that newly-added advertising platform to encoding erasure logic in your data warehouse.

## Data Discovery [#data-discovery]

The Data Inventory can be automatically populated via data discovery, using Transcend's suite of discovery products:

- [System Discovery](../system-discovery/index.mdx) finds your databases, SaaS tools, and vendors.
- [Data Classification](../classification/index.mdx) scans your databases, object stores, and SaaS tools and classifies the data stored inside them, right down to the column or file.
