Leveraging Entity Resolution Technology for Enhanced Master Data Management
TL;DR
- Master Data Management is the governance and operating model for critical business data; entity resolution is the matching, linking, and deduplication layer that helps that model work on messy records.
- Entity resolution improves MDM by finding duplicate, conflicting, or partial records across systems and consolidating them into a more accurate entity view.
- A dedicated entity resolution layer is most useful when MDM teams need deeper matching across disparate data sources, including real-time and retrospective use cases.

Short answer
Entity resolution and Master Data Management solve related but different problems. MDM defines how an organization manages trusted master data across business systems, while entity resolution identifies when multiple records refer to the same customer, product, location, or other entity.
In an MDM architecture, entity resolution is the technical matching layer that turns fragmented source records into a more reliable entity view. For Tilores, that means linking and deduplicating data from disparate sources so downstream systems can query a unified customer or entity context.

Decision guide
| Question | Use Tilores when | Watch-outs |
|---|---|---|
| What problem are you solving? | Duplicate, conflicting, or partial records need to be matched across several source systems before they can support a reliable master view. | MDM governance, stewardship, ownership, and policy decisions still need a separate operating model. |
| Where does the work happen? | Entity assembly happens at ingestion, before downstream systems rely on the resolved customer, product, or entity context. | Do not treat query-time retrieval of a unified context as the same thing as the matching and linking work itself. |
| How fresh does the entity view need to be? | The organization needs both retrospective cleanup and real-time use cases where new records should be matched against existing entities quickly. | A one-off batch migration may not need a dedicated runtime layer if the source data is stable and the matching rules are simple. |
| What should be governed? | Teams need clear control over match criteria, source fields, auditability, and privacy-by-design handling across entity data. | Regulated or sensitive data requires confirmed controls and implementation details; broad compliance guarantees should not be assumed. |
How should MDM and entity resolution work together?
MDM sets the rules for trusted master data: which entities matter, who owns them, how records are stewarded, and how downstream systems consume the master view.
Entity resolution supplies the matching logic beneath that operating model. It finds records that belong together despite typos, missing fields, different identifiers, or system migrations, then helps MDM work from a cleaner entity base.
Where does Tilores fit in an MDM architecture?
Tilores fits as a specialized entity resolution layer for linking and deduplicating records from disparate sources before they are used by MDM, analytics, risk, or customer-facing systems.
The existing Tilores article describes its technology as high-performance entity resolution that deduplicates and links data at scale in milliseconds for both real-time and retrospective use cases.
When is MDM alone not enough?
Modern MDM platforms often include identity resolution or matching features, so the safe question is not whether MDM has any matching at all. The question is whether the matching depth, latency, explainability, and cross-source complexity are enough for the use case.
A dedicated entity resolution layer becomes more relevant when records change continuously, source systems disagree, or customer, product, and location entities must be linked across operational systems without relying on manual cleanup.
What should evaluators test before adding entity resolution to MDM?
Evaluators should test entity resolution on real source data, not only clean sample records. Useful tests include duplicated names, changed addresses, partial identifiers, conflicting attributes, and records that should remain separate.
They should also confirm how matches are reviewed, corrected, audited, and governed over time, especially when entity data supports compliance, risk, lending, customer experience, or other high-stakes workflows.
As enterprises grapple with ever-increasing volumes of data from disparate sources, maintaining accurate and consistent master data becomes a critical challenge.
Entity resolution, also known as record linkage or deduplication, is a key enabler for achieving a single, unified view of entities across diverse datasets in complex organizations.
Master Data Management
Master Data Management (MDM) involves the comprehensive management and maintenance of an organization’s critical business data, ensuring consistency and accuracy across various systems and applications. Entities such as customers, products, or locations are central to MDM, and the effective handling of these entities is crucial for business success.
The Challenge of Data Discrepancies
Organizations encounter challenges in maintaining consistent master data due to data discrepancies arising from data entry errors, system migrations, and the integration of diverse data sources. Duplicate or conflicting records can lead to inaccuracies, operational inefficiencies, and hinder decision-making processes.
Understanding Entity Resolution
Entity resolution (ER) is a technique employed to identify and merge duplicate records or entities within datasets. It involves matching and linking similar records to create a consolidated and accurate representation of a single entity. ER algorithms employ various matching criteria, such as similarity metrics, to determine the degree of match between records.
Benefits of Entity Resolution in Master Data Management:
Data Accuracy and Consistency:
ER technology ensures that master data remains accurate and consistent across different databases and applications, reducing the risk of errors and improving data quality.
Enhanced Decision-Making:
A unified view of entities enables organizations to make more informed decisions, as stakeholders can rely on a single, trustworthy source of master data.
Operational Efficiency:
By eliminating duplicate records, ER technology streamlines data processes, reduces redundancy, and enhances overall operational efficiency.
Compliance and Governance:
ER aids in achieving regulatory compliance by maintaining accurate and auditable master data, benefiting data governance practices.
Customer Experience Improvement:
Ensuring a consistent and accurate customer profile across systems contributes to a seamless and positive customer experience.
Tilores Entity Resolution in Master Data Management
Conventional data management tools struggle with the challenge of resolving data inconsistencies, often necessitating labour-intensive manual interventions.

Tilores is high-performance, entity resolution technology that deduplicates and links data at any scale in milliseconds for both real-time and retrospective use cases.
Developed originally for a German consumer credit bureau, Tilores is data-privacy compliant by design.
Frequently Asked Questions
- Is entity resolution the same as master data management?
- No. Master Data Management is the broader discipline for governing and maintaining trusted business data, while entity resolution is the matching and linking technology that helps identify which records refer to the same entity.
- Can an MDM platform include entity resolution?
- Yes. Many MDM platforms include some matching or deduplication capabilities, but a dedicated entity resolution layer can be useful when matching must handle deeper ambiguity, more source systems, or real-time operational use cases.
- Where should entity resolution happen in an MDM workflow?
- Entity resolution should happen at ingestion or before downstream systems depend on the entity view. Applications can then query or reuse the resolved customer, product, or entity context without repeating the matching work.
- What does Tilores add for MDM teams?
- Tilores adds a specialized layer for deduplicating and linking data from disparate sources, revealing relationships, and supporting both real-time and retrospective entity resolution use cases. Teams should validate the fit against their own source data and governance requirements.
