# Usage

Whether you are using Couchbase for simple caching or as the NoSQL database for an application, your most common operations are going to be getting and setting data.

Data is most commonly a JSON document, but can really be any string you want including binary representations of serialized objects.

For the comprehensive list of SDK methods, parameters, descriptions, and code samples, please look in the [API Docs](http://apidocs.ortussolutions.com/cfcouchbase/2.0.0) (in the download). Click on the `cfcouchbase` package and then the `CouchbaseClient` class.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cfcouchbase.ortusbooks.com/usage.md?ask=<question>&goal=<user_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.
