# Data Management

One of the main feature of Picsellia is Data Management, from storage to versioning through annotation, we will cover everything in this section

To help you store, organize, clean, share and use your data we have developed the following parts :

## 1. The Datalake

The Datalake is the place that will store all your assets,  it is linked to your Organization so every user that belongs to your team will have access to it and work on projects with the data in it.

In the Datalake you can perform actions on the image-level such as :

{% content-ref url="/pages/-MQwZKCJKZYlcQYvnzo6" %}
[Upload assets to your Lake](/picsellia/data-management/upload-assets-to-your-lake.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MQwauz0f4PgUJmYh3tU" %}
[Edit Tags for Pictures](/picsellia/data-management/edit-tags-for-pictures.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MQwWfl-5guVMg3Vib9X" %}
[Create a Dataset](/picsellia/data-management/create-a-dataset.md)
{% endcontent-ref %}

## 2. Datasets and version

The second main object that you can find are the Datasets and its versions.

A Dataset is composed of several version, and each version is composed of multiple assets and the corresponding labels and annotations.

Here are several actions that you can perform on your datasets and their versions :

{% content-ref url="/pages/-MQwjTDAASQvz6D1hoFx" %}
[Add data to a Dataset](/picsellia/data-management/add-data-to-a-dataset.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MQwl0xj6l2R25vTV1fU" %}
[Create a new Dataset version](/picsellia/data-management/create-a-new-dataset-version.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MQwmyn48Fy0BrkqiZDp" %}
[Configure your Labels](/picsellia/data-management/configure-your-labels.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MSE9tMams4w4-dAmWc2" %}
[Create, annotate, review a Dataset](/picsellia/getting-started-2/create-annotate-review-a-dataset.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MQwrGtdn-yEjSa\_xU6N" %}
[Import annotation from other Dataset version](/picsellia/data-management/import-annotation-from-other-dataset-version.md)
{% endcontent-ref %}

## 3. Pictures

As for today, you can only manage Images with our Datalake and Datasets.

When you store an image on Picsellia, a physical copy is made to our internal storage, but the advantage is that when you use this image in different Datasets, only references to this Image are created which lighten and facilitate storage and management of your files.

In order to navigate easily within your Datalake to find some assets, you can add some additional information to your Picture such as Tags :
