Data Management

Data Governance Services

Establish clear ownership, practical policies and a living data catalog, then enforce them through lineage, classification and access controls built into your platforms.

Governance That Enables, Not Just Restricts

Ask three departments what an “active customer” is and you will often get three answers. Ask who may see salary data in the warehouse and the honest answer may be “anyone with a login.” These gaps slow analytics, create privacy exposure and make every AI initiative a lengthy negotiation with legal and security. Yet many governance programs make things worse, producing committees and policy binders that nobody reads.

Hanoi Technology builds governance that people use. We define roles and decision rights that fit your culture, create a business glossary and catalog connected to real assets, classify sensitive data automatically and enforce access and retention rules in the platforms where data actually lives. The result is data that is easier to find, safer to share and simpler to audit.

The Challenge

Common Data Governance Pitfalls

Governance fails when it is disconnected from how people actually work with data.

Policies Without Enforcement

Rules are documented but not implemented in pipelines, catalogs or permissions. Staff work around them and auditors find the gap between policy and practice.

Stewardship as an Unfunded Side Job

Business experts are named stewards without time, tools or authority. Issues pile up and the role becomes a formality.

Catalogs Nobody Opens

A catalog filled automatically with thousands of technical tables but no business context, ownership or quality information gives users little reason to return.

Unknown Sensitive Data

Personal and confidential fields are copied into test environments, spreadsheets and analytics sandboxes without classification, increasing breach and regulatory risk.

Business Value

Why Effective Data Governance Pays Off

Faster Access to the Right Data

Users find certified datasets, definitions and owners in one place and request access through a defined workflow instead of informal favors.

Reduced Privacy and Security Risk

Automated classification and policy-based access keep personal and confidential data visible only to the people who need it.

Consistent Definitions Across the Business

A shared glossary for metrics such as revenue, churn or active user ends conflicting reports and repeated reconciliation.

Simpler Audits and Regulatory Responses

Lineage, access logs and policy evidence answer questions under GDPR, CCPA, HIPAA, SOX or sector rules quickly and consistently.

Safer Adoption of AI

Clear rules on which data may be used for training, retrieval and prompts let AI projects pass review sooner.

Measurable Accountability

Owners, stewards and service levels are defined for each critical domain, and progress is tracked with clear metrics.

Governance Belongs in the Platform

Modern data platforms such as Microsoft Purview, Databricks Unity Catalog and Snowflake Horizon make it possible to apply governance as code: tags, masking, row filters and lineage applied automatically. We help you use these capabilities so that policies are enforced by default rather than remembered by individuals.

    Deliverables: Operating model and RACI · Policy framework

  3. 03

    Launch a Pilot Domain

    We implement glossary, catalog, lineage, classification and access controls for one high-value domain, such as customer or finance.

    Deliverables: Governed pilot domain · Steward onboarding

  4. 04

    Automate Enforcement

    We configure policies as tags, masks and permissions in your platforms and connect quality scores and ownership into the catalog.

    Deliverables: Policy-as-code configuration · Catalog with quality and ownership

  5. 05

    Scale and Measure

    We roll out to further domains, track adoption and compliance metrics and refine the model based on feedback.

Use Cases

Data Governance in Action

Examples of governance problems we help solve.

Self-Service Analytics with Guardrails

A retailer opens its lakehouse to business analysts while masking customer personal data automatically by role.

Metric Standardization

A SaaS company agrees one definition of annual recurring revenue and churn, certifies the dataset and retires conflicting spreadsheets.

GDPR and CCPA Readiness

A consumer platform maps where personal data is stored and processed and implements retention rules and deletion workflows.

Lineage for Regulatory Reports

A financial services firm traces each regulatory figure from source system to final report, simplifying audit preparation.

Safe Data for AI Assistants

An enterprise defines which document repositories may feed an internal copilot and enforces source permissions at retrieval time.

Governance After Cloud Migration

A company moving to Snowflake or Databricks rebuilds access policies centrally instead of copying ad-hoc legacy grants.

Data Governance FAQ

How do we start data governance without creating bureaucracy?

Start with one domain where poor governance causes visible pain, such as conflicting revenue figures or uncontrolled access to customer data. Define a small set of roles, a handful of policies and clear success measures, and implement them in the tools people already use. Once that domain shows results, extend the model. Councils and formal policies should be introduced only as fast as they are needed to make decisions, not as a prerequisite.

Which governance model is right for us: centralized, federated or data mesh?

It depends on size, regulatory pressure and how independent your business units are. Centralized models suit smaller or heavily regulated organizations that need tight control. Federated models give domains ownership of their data within shared standards and suit most mid-size and large enterprises. Data mesh goes further, treating domain data as products. We assess your context and often recommend a federated model with central standards and platform-enforced policies.

What does a data steward actually do?

A data steward is the business expert accountable for the meaning and quality of data in a domain. Stewards maintain glossary definitions, approve quality rules, triage data issues, review access requests and act as the contact point for questions about their data. To succeed, they need protected time, clear authority and tooling such as a catalog and issue workflow. We define the role, train stewards and set realistic expectations for their workload.

Do we need a dedicated catalog tool such as Collibra or Alation?

Not always. If your data lives mainly in one platform, native capabilities in Microsoft Purview, Databricks Unity Catalog or Snowflake Horizon may cover your needs at lower cost. Dedicated catalogs add value across many heterogeneous systems, with richer workflows, business-friendly interfaces and broader connectors. We compare options against your landscape, users and budget, and we can also implement open-source catalogs such as DataHub or OpenMetadata.

How does data governance support AI initiatives?

AI multiplies governance needs. Teams must know which data may be used for training or retrieval, whether personal data is included, who owns the source and how fresh it is. Governance provides classification, lineage, ownership and access policies that answer these questions quickly. We also help define AI usage policies, document models and datasets, and enforce document-level permissions in retrieval systems so assistants only reveal what each user may see.

How do you measure the success of a governance program?

We agree metrics at the start, such as the share of critical data elements with an owner, catalog adoption by active users, time to grant data access, quality scores for certified datasets, number of policy exceptions and time to answer audit requests. These are reported in a governance scorecard reviewed regularly with sponsors. Measuring outcomes rather than the number of documents produced keeps the program focused on real business value.
