# Data sets

The applications have access to (master) data from external data sources (**import data**). In addition, **entered data** can also be written to external data sources (**export data**) again by using a [**data hub**](/any2info-academy/no-code-platform/data-studio/data-hubs.md). 

Any2info uses **a so-called** [**dataclip**](/any2info-academy/no-code-platform/data-studio/data-clips.md) **as a tool to be able to use datasets in its applications**.

Data clips are data tables that represent datasets directly from a data source or created by using dataflows in the data hub.

These tables are used for visualising data on dashboards and/or for data entry and selections in a form using lists, trees, status, etc..

A dataclip is a data table consisting of a series of columns (headers) and rows where each row is characterized by a unique ID.

There are **3 types of dataclips - connections:**

* **Push**: The data traffic is configured in de Data Studio using the services of the data hub. A data hub has a series of configured connectors that can access a specific source for data retrieval.&#x20;
* **SQL**: The data traffic is initiated by applying a query to the platform's database (SQL).
* **Pull**: Data traffic is initiated from a client device.

The most commonly used dataclip type is a **push dataclip** **that is created as a result of a data flow.**&#x20;

**All dataclips are stored in the Any2info database (SQL).**

### Mapping data

Linking the content of a dataclip to components on dashboards and/or forms is called **Mapping**.&#x20;

See the separate explanation for [**forms**](/any2info-academy/no-code-platform/app-studio/data/mapping-form-data.md) here and for [**dashboards**](/any2info-academy/no-code-platform/app-studio/data/mapping-dashboard-data.md) here.
