# Accessing Data
Learn how end users can access policy-enforced data in PostgreSQL
Once data is registered through the PostgreSQL connection, you will access your data through your PostgreSQL client as you normally would. If you are subscribed to the data source, Immuta grants you access to the data in PostgreSQL.
When you submit a query, the PostgreSQL client submits the SQL query to the PostgreSQL server, which then processes the query and determines what data your role is allowed to see. Then, the PostgreSQL server queries the database and returns the query results to the PostgreSQL client, which then returns policy-enforced data to you.
The diagram below illustrates how Immuta, the PostgreSQL server, and PostgreSQL client interact to access data.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://documentation.immuta.com/SaaS/configuration/integrations/postgresql/reference-guides/accessing-data.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
