Master Data Management Showdown:
AI-Native MDM vs. Rules-Based MDM

Not sure which solution is right for you? Let’s look at head-to-head comparisons.

AI-native master data management (MDM) is a modern approach that uses machine learning and human feedback to unify, clean, and enrich data across silos and sources — producing golden records that are accurate, complete, and continuously maintained. Tamr provides the industry-leading AI-native MDM platform.

A rules-based approach to MDM uses coding logic and manual processes to standardize and match data across systems. It requires constant rule updates, centralized control, teams of people to maintain, and significant effort to scale. Examples: Informatica, Boomi, IBM Infosphere, Reltio.

Speed & Costs Comparison
AI-Native MDM
Rules-Based MDM

Time-to-value

Fast outcomes — Time-to-value achieved in days or weeks

Slow returns — Takes months to years to reconcile and create trustworthy data

Upfront costs

30% cheaper with AI-driven automation

High costs due to extensive manual intervention and specialized teams required

Ongoing maintenance

Pre-trained AI models reduce the need for constant updates

Rules-based systems require ongoing tuning and manual rule-writing

Operational costs

Lower infrastructure, licensing, and personnel costs

Higher governance, policy, and process-driven operational costs

"To master 375 million records using the traditional way of writing rules, we'd be doing it for 10 years and probably still wouldn't be able to do it."

Chief Data Architect
Accuracy Comparison
AI-Native MDM
Rules-Based MDM

Deduplication and matching

Proven, patented referential matching delivers unmatched deduplication results and better entity resolution

Manual rules and preparation risk inconsistencies and data errors; rules-based logic struggles with ambiguous data

Automation and efficiency

AI-driven automation reduces data curation needs by 90%, boosting accuracy

High dependency on manual intervention and processes that are laborious, time-consuming, and error-prone

Trustworthy insights

Golden records reduce report and dashboard creation time by 80% or more and build stakeholder trust

Extensive manual data manipulation means less timely and less justifiable insights

Measurable progress

Move beyond basic metrics like fill rates to better understand the state of your data and track its improvement over time

Lack of visibility into how data evolves makes it impossible to reliably measure the data quality progress

Comprehensiveness Comparison
AI-Native MDM
Rules-Based MDM

Data quality and completeness

Unifies data across systems and silos; proven machine learning models ensure comprehensive and complete high-value data

Requires manual development of data-quality logic; gaps and inconsistencies persist

Verified match

Your data, refined with AI and verified against a massive master database for accuracy, improves trust and outcomes

No out-of-the-box, third-party data verification

Third-party enrichment

One-click, third-party enrichment enhances data and adds context

Often requires custom development or data reformatting to use external sources

Scalability across domains

Purpose-built data products with domain-specific schema speed up data onboarding and curation

Built for static data — struggles to scale across business units or regions

Senior Manager of Engineering
Durability Comparison
AI-Native MDM
Rules-Based MDM

AI-powered search

Keeps data clean and prevents duplicate records with intelligent "search before create" and entity resolution capabilities

Traditional search struggles with multi-system, multi-domain entity identification

Onboarding of new data sources

Connects and reconciles new data sources in hours using AI-driven automation

Requires manual updates — limiting adaptability to changing data

Real-time APIs

Resolves entities while the data is still in motion and instantly delivers the best data to operational systems

Monolithic platforms require complex efforts to maintain data accuracy

Data governance and stewardship

Empowers data teams with intuitive tools for ongoing data curation and governance

Heavy reliance on manual processes increases the risk of errors and delays

"Data mastered by Tamr underpins the entire digital journey. If we didn't have the single customer view, we wouldn't be able to feed information downstream into decision and risk engines."
Jonathan Holman
Head of Digital Transformation

The choice is clear: When it comes to mastering data to deliver business value, AI-native MDM wins
Overcome the limits of rigid, rules-based solutions, and gain the flexibility to adapt to the needs of your business. With decentralized governance — along with an intuitive interface and seamless integration — put the management and control of data into the hands of the people who need it to drive business growth, even as your data changes.
