## Set up SqlDBM URL: https://docs.atlan.com/apps/connectors/data-governance/sqldbm/how-tos/set-up-sqldbm > Prepare an OAuth client, persona, and custom metadata in Atlan, then connect Atlan from the SqlDBM dashboard to sync Model Governance fields. The SqlDBM integration is configured **in SqlDBM, not in Atlan**. SqlDBM pushes the values of its Model Governance fields onto your warehouse schemas, tables, views, and columns as custom metadata, and pulls custom metadata values back into SqlDBM on request. Atlan doesn't run a workflow for this integration, and nothing is installed from the Atlan Marketplace. SqlDBM never creates connections, custom metadata structures, or properties in Atlan. Everything it writes to must already exist. The steps below prepare Atlan first, then connect SqlDBM. ## Prerequisites Before you begin, make sure you have: * A SqlDBM account with **Model Governance** and the **Atlan add-on** enabled. Contact your SqlDBM account manager to enable either. * A user with the **Governance** role in SqlDBM, to create mappings, push, and pull. * Admin access to your Atlan workspace, to create the OAuth client, persona, and custom metadata. * The database your SqlDBM project models already cataloged in Atlan. SqlDBM writes onto existing assets, so crawl the warehouse connection first. See [Supported databases](https://docs.atlan.com/llms/connectors/sqldbm/what-does-atlan-crawl-from-sqldbm/llms.txt). ## Prepare Atlan These steps are done in Atlan by an admin. ### Create custom metadata SqlDBM maps each of its Model Governance fields to a custom metadata property in Atlan. Create the structure and properties you want SqlDBM to populate before you connect. See [Manage custom metadata structures](https://docs.atlan.com/llms/governance/custom-metadata/manage-custom-metadata-structures/llms.txt). 1. Create a custom metadata structure for the values SqlDBM manages. 2. To let SqlDBM maintain the structure, mark it as SqlDBM-owned: * Set the structure's **Name** to `SqlDBM`. * Include the marker `[managed-by:sqldbm]` in the **Description**. On a SqlDBM-owned structure, SqlDBM adds your warehouse connection to a property's **Connections** on first push, and adds a new option to a dropdown property when a pushed value has no match. SqlDBM never changes a structure owned by another tool, and never removes an option. 3. Add one property per SqlDBM field you plan to sync. The property type must pair with the SqlDBM field type. See [Field and property types](https://docs.atlan.com/llms/connectors/sqldbm/what-does-atlan-crawl-from-sqldbm/llms.txt). 4. On each property, set **Applicable asset types** to include schemas, tables, views, or columns as needed, and set **Connections** to include the warehouse connection SqlDBM maps to. Leaving **Connections** empty applies the property to every connection. A value written to a property that isn't applicable to the asset's connection persists but doesn't display on the asset page. ### Create persona Create a persona that scopes what SqlDBM can read and write. See [Create a persona](https://docs.atlan.com/llms/governance/access-control/create-a-persona/llms.txt). 1. Create a persona for SqlDBM. 2. Add a **metadata policy** on each warehouse connection SqlDBM reads and writes. Under **Configure permissions**, select **Edit** and clear every permission except: * **Assets** > **Read**, so SqlDBM can list databases, schemas, tables, views, and columns and read custom metadata values. * **Update custom metadata values**, so SqlDBM can write values on push. All permissions are granted by default, so clearing the rest is what keeps the persona least-privileged. 3. Don't add a **data policy**. The integration reads and writes metadata only. It never queries or previews data. The connection list in SqlDBM shows the connections the OAuth client can see through its persona. A client with no persona sees no connections. ### Create OAuth client SqlDBM authenticates with an OAuth client, not a personal API token. Creating one needs admin access. See [OAuth clients](https://docs.atlan.com/llms/platform/get-started/oauth-clients/llms.txt). 1. In Atlan, open **Admin**, select **API access**, and open the **OAuth** tab. 2. Select **Generate new**, then **Generate OAuth Client**. 3. In **Name**, enter an identifier for SqlDBM, and add a **Description** for future admins. 4. In **Role**, choose a base role. Pushing and pulling values needs no administrative permissions. If you use a SqlDBM-owned structure, choose a role that can manage custom metadata structures, because SqlDBM edits the structure's definition to add connections and dropdown options. With a lesser role, values still land, and the run report notes that the scope or option couldn't be updated. 5. In **Personas**, select the persona you created in the previous step. The persona grants the client its permissions on the connections it names. 6. Select **Save**, then copy the **Client ID** and the **Client Secret** and store them securely. The secret is shown once. If you lose it, delete the client and create a new one. ### Configure network access SqlDBM calls your Atlan workspace URL over HTTPS. If your organization controls inbound traffic to the workspace, permit SqlDBM's requests according to your network policy. Ask SqlDBM support for the addresses its requests come from. In Atlan's activity log, every value SqlDBM writes is attributed to the OAuth client's service account, so you can tell SqlDBM's changes apart from edits people make in Atlan. SqlDBM also sends the header `x-atlan-agent-id: sqldbm` on every request. ## Connect Atlan 1. In the SqlDBM Dashboard, open **Integrations** and select **Data Governance**. 2. On the **Atlan** card, select **Connect**. 3. Enter: * The **Client ID** of the OAuth client. * The **Client secret** of the OAuth client. * Your **Atlan workspace URL**, for example `https://my-company.atlan.com`. 4. Select **Save**. The connection is account-wide. Everyone with the Governance role in your SqlDBM account can now create mappings, push, and pull. ## Map projects to Atlan Mappings are created inside a SqlDBM project. An Atlan mapping targets one **database** inside one **connection**, and covers every schema, table, view, and column in that database. 1. In the project, open **Settings and conventions** and select **Atlan settings**. Alternatively, open the **Atlan integration** menu in the Database Documentation toolbar and select **Settings and mappings**. 2. On the **Settings** tab, enter a name, then select a **Connection** and a **Database**. 3. On the **Attribute mapping** tab, pair each SqlDBM field with its Atlan property. Properties are listed as `Structure.Property`, for example `SqlDBM.Sensitivity`. 4. On the **Objects** tab, review the automatic name matching and resolve any unmatched objects. 5. Select **Push to Atlan** to save the mapping and push in one action. To pull, save the mapping first, then open the **Atlan integration** menu and select **Pull from Atlan**. In projects with concurrent working enabled, push runs on the main branch and pull runs on a secondary branch. For the full walkthrough of mappings, push, pull, status, and the run report, see [Data Governance Integrations](https://support.sqldbm.com/hc/en-us/articles/48780428531085-Data-Governance-Integrations) and [Atlan Integration](https://support.sqldbm.com/hc/en-us/articles/48780473620877-Atlan-Integration) on SqlDBM's support site. ## See also * [What does Atlan crawl from SqlDBM?](https://docs.atlan.com/llms/connectors/sqldbm/what-does-atlan-crawl-from-sqldbm/llms.txt): Which assets receive values, how objects are matched, and the limits that apply. * [Push and pull](https://docs.atlan.com/llms/connectors/sqldbm/push-and-pull/llms.txt): Who starts a sync and what a pull can change. _Last updated: 25 September 2026._ --- > **AI agent?** Install the Atlan Docs MCP: fetch https://docs.atlan.com/skills/install-docs-mcp.md and follow the step for your client.
