## How to Integrate MongoDB Atlas with Purview
37+
38+
### Registration and Access Setup
39+
40+
- Use a **custom connector** or ODBC/JDBC bridge to connect MongoDB Atlas to Purview.
41+
- Grant read-only API access to metadata via [MongoDB Atlas Data API](https://www.mongodb.com/docs/atlas/api/data-api/).
42+
- Configure network access using VPC/VNet peering or Private Endpoint.
43+
- Register the data source in **Purview Studio** under **Other Sources** → **Generic NoSQL**.
44+
45+
### Metadata and Lineage Scanning
46+
47+
- Define collections and fields to scan using JSON paths or regex.
48+
- Schedule regular scans to detect schema drift.
49+
- Connect MongoDB ingestion pipelines (e.g., via Azure Data Factory) to enable **lineage tracing**.
50+
51+
### Classification and Labeling
52+
53+
- Use built-in classifiers or define custom tags like `document_id`, `user_email`, `customer_journey`.
54+
- Label fields using Microsoft Information Protection (MIP): e.g., Confidential, Restricted.
55+
- Configure label inheritance across nested documents and arrays.
56+
57+
## Governance and DLP Controls
58+
59+
> Protect sensitive document structures across customer, analytics, and operational data models.
60+
61+
<details>
62+
<summary><b>E.g: DLP Policy for CRM Records</b> (Click to expand)</summary>
63+
64+
> Apply governance to `customers`, `leads`, `interactions`.
65+
66+
**Steps:**
67+
1. **Classify Fields:** `customer_name`, `contact_info`, `lead_source`.
68+
2. **Set Policy Triggers:** Block JSON exports exceeding 100 records/hour.
69+
3. **Apply Actions:**
70+
- Mask names and contact info for sales interns.
71+
- Enforce MFA for modification privileges.
72+
4. **Monitor:** Enable dashboard alerts on unusual query bursts.
73+

76+
<details>
77+
<summary><b>E.g: DLP Policy for Financial Forecasts</b> (Click to expand)</summary>
78+
79+
> Secure forecasting models stored in `budgets`, `models`, `assumptions`.
80+
81+
**Steps:**
82+
1. **Scope:** Forecasted revenue, cost-of-sales fields.
83+
2. **Detection Rules:** Numeric limits, field tags (e.g., `model_id`, `confidence_score`).
84+
3. **Actions:**
85+
- Encrypt collections at-rest with customer-managed keys.
86+
- Allow read-only access from trusted Azure regions.
87+
4. **Audits:** Maintain access logs for at least 12 months.

<summary><b>E.g: DLP Policy for Legal Contracts</b> (Click to expand)</summary>
93+
94+
> Protect legal content in `contracts`, `legal_reviews`, `negotiations`.
95+
96+
**Steps:**
97+
1. **Tag Fields:** `contract_number`, `counterparty`, `signature_date`.
98+
2. **Policy Actions:**
99+
- Restrict full-text searches by non-legal roles.
100+
- Block download/printing of full documents.
101+
3. **Alerting:** Trigger alerts if accessed outside office hours.

<summary><b>E.g: DLP Policy for Product Telemetry</b> (Click to expand)</summary>
107+
108+
> Manage telemetry in `events`, `device_stats`, `system_logs`.
109+
110+
**Steps:**
111+
1. **Classify Columns:** Device IDs, geographic coordinates.
112+
2. **Policies:**
113+
- Mask PII from telemetry streams ingested via Event Hubs.
114+
- Block data streaming to unknown destinations.
115+
3. **Monitoring:** Visualize flows with lineage diagrams in Purview.

## Cost Insights
120+
121+
> [!NOTE]
122+
> MongoDB Atlas and Purview are billed independently.
123+
124+
- **MongoDB Atlas**: Billed by storage, cluster tier, backup snapshots, and network usage.
125+
- **Microsoft Purview**: Charges for metadata scanning, vCore hours, and classification volume.
126+
- Optimize by:
127+
- Using partial scans via field inclusion/exclusion.
128+
- Defining metadata rules for incremental ingestion.
129+
130+
## Governance Best Practices
131+
132+
- **Schema Versioning:** Track field changes across collections via Purview logs.
133+
- **Security Groups:** Align Purview roles with Atlas database access controls.
134+
- **Data Domains:** Categorize assets by purpose (Operational, Analytical, Archival).
135+
- **Threat Detection:** Integrate with Microsoft Defender for threat telemetry.
136+
137+
## Unity Catalog Integration
138+
139+
> If paired with Azure Synapse or Databricks, MongoDB Atlas lineage can be extended via Unity Catalog.
140+
141+
### Steps
142+
143+
1. Use a **Synapse Link** or **Azure Data Factory** to flow data from MongoDB Atlas.
144+
2. Register all destination data assets in Microsoft Purview.
145+
3. Map lineage: `MongoDB Atlas → Azure Data Lake → Power BI/Dashboards`.
146+
4. Visualize and enforce domain-specific policies.
147+
148+
### Benefits
149+
150+
- Secure NoSQL lineage from ingestion to analytics.
151+
- Unified discovery across structured and document databases.
152+
- Role-based governance over sensitive fields.
