# Data structure overview

What is the overall structure of the data in our solution?

Our API is built around resources in REST style, so understanding our data structure also gives you an overview of how the API is organized. We use two main categories of resources:

* **Technical resources:** Handle platform management and integrations, such as users, roles permissions, and webhook subscriptions.
* **Business resources:** Represent the core elements of your tokenization process, such as assets, investors, and wallets.

## Brief overview of the resources

The diagram below shows how these resources connect in your tokenization workflows:

Each resource is explained in detail on the related pages, but below you can find a very brief overview:
