# Platform administration

Platform administration covers the **foundational organization and resource capabilities** within an AI Studio workspace: workspaces and members, Catalog and compute instances, and cross-workspace data sharing and subscriptions.

Start by setting up a workspace, then configure members and resources, and finally share data as needed.

## What you can do in this section

- Create, switch, and manage **workspaces**
- Guide members through joining and role assignment (full operations are under User Permissions)
- Browse and manage **Catalog** data assets
- Create and manage **compute instances** for queries or tasks
- **Publish** data to other workspaces or **subscribe** to data published by others

## Pages in this section

| Page | Contents |
| --- | --- |
| [Workspaces](workspace.md) | Switch, create, rename, and delete workspaces; copy IDs; home-page overview |
| [Member management](members.md) | Entry points and recommended order, with links to complete operations under User Permissions |
| [Catalog](catalog.md) | Object tree, browsing, create/delete/update operations, versions, and connection strings |
| [Manage Catalog basic objects](catalog-objects.md) | Create, edit, and delete catalogs, databases, tables, and volumes |
| [Compute instances](compute.md) | Query/task selection, default instances, elasticity and billing, creation and management |
| [Data sharing](share-data.md) | Publish selected Catalog objects to specified workspaces |
| [Data subscriptions](subscribe.md) | Subscribe to publications and manage subscribed libraries, permissions, and validity periods |
| [Models and operators](models-and-operators.md) | Models and custom operators |

## Recommended order

1. [Workspaces](workspace.md): confirm the current workspace or create a project workspace.
2. [Member management](members.md) → [User permissions](../permissions/index.md): invite colleagues and assign roles.
3. [Catalog](catalog.md): prepare directories and databases for storing data.
4. [Compute instances](compute.md): create dedicated instances as needed, or start with platform defaults.
5. After the data is ready, use [Data sharing](share-data.md) and [Data subscriptions](subscribe.md) to collaborate across workspaces.

## Boundaries with other modules

| Topic | Where to go |
| --- | --- |
| Invitations, roles, and permission-point configuration | [User permissions](../permissions/index.md) |
| Connectors, loading, and export | [Data connections](../data-sources/index.md) |
| Workflows and SQL editor | [Data processing](../processing/index.md) |
| Knowledge bases and agents | [Knowledge bases](../knowledge-bases/index.md), [Agents](../agents/index.md) |
| Credit and bills | [Cost and billing](../../billing/index.md) |
| MatrixOne instances and SQL privileges | [MatrixOne](../../matrixone/index.md) |
