# DataModel

DataModel : `ServiceProvider`

## Overview

As the top-level hierarchical element structuring the entire game, it encompasses various core services.

Essential game elements like Workspace and Lighting are children of the DataModel, accessible globally via game, which is a global object

## Properties

### JobId

`string`

This property returns a unique identifier that distinguishes the currently running game server instance.

Even servers sharing the same PlaceId have different JobId values per instance, so it can be used to identify a specific server session or for logging and analytics purposes.

#### Code Samples

### PlaceId

`string`

This property returns the ID of the Place currently running on the server.

The PlaceId identifies a published world, and all server instances launched from the same place share the same value.

#### Code Samples

### Workspace

`Workspace`

This property provides access to the Workspace service, which manages the game's 3D world space and physical environment. Most 3D objects placed in the world, such as parts, models, and characters, are contained under this Workspace.
