# Data Quality Rules

Data quality rules are essential for maintaining trustworthy data. The predefined standards evaluate various aspects of data quality, guaranteeing data reliability for crucial tasks like decision-making and analysis.

Each rule works with a specific function to check data quality. These functions, like accuracy or completeness checks, analyze data against defined criteria.

OvalEdge offers pre-built data quality functions for various criteria, allowing users to create rules easily. Additionally, users can tailor rules to their specific needs by creating custom functions through the "Load Metadata From Files" template.

This approach allows users to ensure their data meets the quality standards required for their business operations.

## 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.ovaledge.com/release8.2/data-quality/data-quality-rules.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.
