DQC

The Overview tab

The Overview tab is automatically created for every table connected to the DQC Platform. It provides a high-level summary of the table’s context, validation activity, and overall data quality trends — making it the starting point for understanding the health of your data.

Table description

At the top of the tab, you can add a description of the table to give context for other users. This description can be:

  • ✍ Entered manually

  • 🤖 Generated automatically using the AI Assistant

Help other users understand the content and purpose of the table

Quality trend chart

At the bottom of the Overview tab, you’ll find a trend visualization that shows how data quality has evolved over time.

The chart includes:

  • Issues – Total number of issues found in the table per run

  • Quality Ratio – Percentage of valid rows vs. total evaluated rows

Track improvements or spikes in data issues

You can also select a custom date range to narrow the view to a specific time window — ideal for reporting or analyzing recent changes.
