# Master Data

**Master Data** section houses the core data, for example clients, vessels, etc., accounting parameters and any other data required to successfully operate the different modules of the system. Master Data is a single source of basic business data used across the VMS in the modules and is shared by multiple users. To enable full usage of the system it is necessary to enter data into this section.

Each master data page follows the same design where you get a list of master data when opening the page. Create a new master data object with the + button above the list and maintains the master data object by open a drawer when clicking a master data object in the list.<br>

## 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://docs.dataloy.com/release-5.48/voyage-management-system/step-by-step-guides/master-data.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.
