# Data Hub
The **Data Hub** in YouDesign Models enables users to search, filter, and add data from ServiceNow tables directly onto boards.
## Using the Data Hub
### Steps to Use the Data Hub
#### 1. Open Data Hub Panel
Click on the **Data Hub** icon in the Control Bar to open the panel on the left side of the screen.
#### 2. Select or Search for a Table
Click on **Select source table** to choose or search for a table. Tables are grouped by Shape Categories and only tables with the Data Hub option activated for a shape are displayed.
#### 3. View Data Results
Once you select a table (e.g., Business Capability), the data will be shown in the Results section.
## Adding Items to the Board
You can add items from the Data Hub to the board using two methods:
### Drag & Drop
* Drag an item from the Results list and drop it on the board.
### Click & Click
* Click on the item in the Results list, move the mouse to the board, and click again to place the item.
### Adding Multiple Items or Hierarchies
#### Multiple Items
Drag & Drop the top item representing the table name to add all or multiple items from the search result.
#### Hierarchy of Items
Drag & Drop a parent hierarchy item, and YouDesign Models will load the full sub-hierarchy including child items.
## Data Hub Search
To search for specific data within the selected table, enter the search string, and YouDesign Models will return matching results.
## Data Hub Filter
YouDesign Models's filtering system offers three levels of filtering—Global, Teamspace, and Personal filters. These filters ensure only relevant data is shown based on user roles.
| Filter | Description | Role |
| ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------- |
| **Global** | Applied across all Teamspaces and Boards by YouDesign Models Admin. Cannot be changed by other users. | YouDesign Models Admin |
| **Teamspace** | Defined by the Teamspace Admin and applied across all Boards within the Teamspace. Only Teamspace Admins and YouDesign Models Admins can change these settings. | Teamspace Admin |
| **Personal** | Personal filters are specific to Editors. These are only visible to the user and are applied after Global and Teamspace filters. | Editor (login user) |
### Applying Personal Filters
To apply **Personal Filters**, simply turn on the switch in the **Personal filter chip** for the selected table.
## Dropping Items into Frames or Groups
When you drag a Data Hub item onto a **frame**, **group**, or **visualization container**, YouDesign Models validates whether that container accepts the item as a member:
* **Valid** — the item is added inside the container.
* **Invalid** — the drop is silently rejected. The item is not added, and nothing appears on the canvas.
Most standard shapes drop into frames and groups without issue. Invalid combinations include dropping a frame into another frame, or dropping a shape onto a container on a different layer.
**Exception:** If the drop would create an invalid relationship in a **Hierarchy Map**, a notification appears explaining why. For other container types, the rejection is silent — if a drop seems to "do nothing," try dropping onto an empty area of the canvas instead and then moving it manually.
