# Data Quality

Roaming only works if the data behind it is accurate. Every driver session, every invoice, every app map view depends on a chain of OCPI objects synced correctly between dozens of partners — each with their own implementation quirks. Things drift. Tokens expire. Locations get removed without being marked removed. Tariffs get detached from connectors.

The Data Quality page is your visibility layer into that chain. This section covers how to read it, how to monitor your connections, and how to fix the issues that come up most often.

### In this section

Use these pages to move from visibility to action:

* [Introduction to the Data Quality Page](/data-quality/introduction-to-the-data-quality-page.md) — learn the page layout and the two main views.
* [Understanding Object Counts](/data-quality/understanding-object-counts.md) — understand what the counts include.
* [The Sync Activity Log](/data-quality/the-sync-activity-log.md) — review recent sync jobs and outcomes.
* [Monitoring Your Connections](/data-quality/monitoring-your-connections.md) — know when and how often to check.
* [Common Data Quality Issues and Fixes](/data-quality/common-data-quality-issues-and-fixes.md) — troubleshoot the most common gaps.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enapi.com/data-quality.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
