# Crawling

Crawling is the process of collecting metadata from a connected data source. This metadata includes details such as databases, tables, columns, reports, files, code, APIs, and their attributes.

Data sources can include systems like databases, data lakes, or reporting tools.
 After crawling is complete, the collected metadata will be available in the Data Catalog.

**Example**:\
For a SQL Server data source, crawling retrieves information such as Table Name, Column Name, Data Type, Data Type Size, Title, and Description.\
The screenshot below shows metadata from a sample database table in a SQL Server Data Source.

The system connects to the SQL Server, crawls the table, and fetches the metadata as shown.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/connectors/introduction-to-connectors/connector-features/crawling.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.
