# GraphDatabase

> Provides functionality needed to access, and perform operations on, graph assets.

## Definition

* **Type:** Class
* **Namespace:** [Unity.GraphToolkit.Editor](/engine/6000.7/script-reference/unity/graphtoolkit/editor.md)
* **Assembly:** UnityEditor

```csharp
public static class GraphDatabase
```

## Remarks

The `GraphDatabase` class is similar to Unity's [AssetDatabase](/engine/6000.7/script-reference/unityeditor/assetdatabase.md), but it is tailored for graph-based tools. Use this class to create, load, and save [Graph](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graph.md) instances and their associated assets. This API supports typical asset workflows such as creating new graph assets in the Project window, accessing graphs by path or GUID, and ensuring changes to graph data are saved.

Use [GraphDatabase.PromptInProjectBrowserToCreateNewAsset](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphdatabase/promptinprojectbrowsertocreatenewasset.md) to create and name a new asset, [GraphDatabase.CreateGraph](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphdatabase/creategraph.md) to generate an asset file, and [GraphDatabase.LoadGraph](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphdatabase/loadgraph.md) to retrieve an existing one.

Use [GraphDatabase.SaveGraph](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphdatabase/savegraph.md) to persist graph data changes, and [GraphDatabase.LoadGraphForImporter](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphdatabase/loadgraphforimporter.md) to load a clean instance during import.
