# Disconnected mode

## Disconnected mode 

In disconnected mode, the application connects to a database, retrieves the required data, and then disconnects from the database. Once the data has been retrieved, the application can work with the data offline without keeping a continuous connection to the database. In this mode, the database is accessed only when necessary, which can help reduce network traffic and improve application performance.

{% hint style="info" %}
In ADO.NET, the "disconnected mode" refers to a data access model where a connection to a data source is opened, data is retrieved from the data source, and then the connection is closed immediately. The data is then held in a disconnected state in a dataset or data table object.
{% endhint %}

Let us discuss how to create and read a database in disconnected mode using ADO.NET

## 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://raviram.gitbook.io/ado.net-core/code/disconnected-mode.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.
