01
MDM implementation services for when the platform is the easy part
Buying an MDM platform takes a quarter. Getting a golden record people trust takes longer, and it depends far less on the software than on the decisions behind it: which sources count, how records match, which value wins when sources disagree, and who resolves the cases the rules cannot. Platforms implemented without those decisions end up as an expensive copy of the duplicates they were bought to remove.
Greenwolf designs and builds that layer. We work on Informatica, Reltio and Veeva Network, and on lighter warehouse-based masters when a platform is not yet justified. We design the model, write and tune the match and survivorship rules, integrate the sources, set up stewardship, and build the feeds that carry mastered data to CRM and the warehouse. For the broader service, see master data management services.
02
Do you need an enterprise MDM platform?
Not always. A platform earns its cost when several of these are true:
- Many source systems create or change the same customer, product or supplier records.
- Records must be mastered in near real time, not overnight.
- Several downstream systems, such as CRM, ERP and the warehouse, need the same golden record.
- You need a stewardship interface, audit trail and change history for compliance.
- Hierarchies and relationships (accounts, affiliations, households) matter as much as the records themselves.
If you have three or four sources, a batch cadence and one main consumer, a well-built master in your warehouse, with documented match rules and a simple review queue, is often the better first step. It can be moved to a platform later because the rules travel with it. We will tell you which side of that line you are on. For the difference between within-source and across-source mastering, see types of MDM.

The platforms we work on
Informatica MDM
Informatica's cloud MDM runs as MDM SaaS inside its Intelligent Data Management Cloud (IDMC), alongside its data integration and data quality services, with Customer 360 as its customer domain. Salesforce completed its acquisition of Informatica in November 2025.
- Customer 360 and multidomain models
- Match and merge configuration
- Integration and data quality on IDMC
Reltio
Reltio is a cloud-native MDM platform, sold as Reltio Data Cloud, with multidomain mastering, a graph model for relationships, industry data models including life sciences, and AgentFlow for AI agents.
- Entity and relationship modelling
- Match rules and ML matching
- Real-time APIs to consumers
Veeva Network and OpenData
Veeva Network is Veeva's multi-domain MDM for life sciences, natively integrated with Vault CRM, and Veeva OpenData supplies HCP and HCO reference data to validate against.
- HCP and HCO masters
- Affiliations and hierarchies
- OpenData change requests
Warehouse-based masters
Masters built in Snowflake, Databricks or Microsoft Fabric with documented rules and review queues, for teams not yet ready for a platform.
- SQL and Python match logic
- Steward review queues
- A path to a platform later
04
Pharma: HCP, HCO and patient masters
Pharma has its own MDM shape. HCP and HCO records arrive from CRM, syndicated data, specialty pharmacies, hubs and claims, each with its own identifiers. Many companies use Veeva Network as the customer master, validated against OpenData or another reference source, and then still need to link that master to the patient-level and specialty pharmacy data that sits outside it. We build those links, and the patient master that has to stay de-identified where the work allows. See customer master data management, patient master data management and Veeva CRM data integration.
05
Matching, survivorship and stewardship
Deciding which records are the same entity
We combine deterministic rules on trusted identifiers (NPI, DEA, tax ID, an internal key) with fuzzy rules on names and addresses and, where the platform supports it, machine learning suggestions. Every rule is tested on a labelled sample so you know its false match and missed match rates before it goes live.
- Deterministic and fuzzy rules
- Tested on labelled samples
- Thresholds agreed with the business
Deciding which value wins
When matched records disagree, survivorship picks the value to keep: the most trusted source, the most recent update, the most complete value, or a rule per attribute. We write these down attribute by attribute and agree them with the business owner of each source.
- Source trust rankings
- Recency and completeness rules
- Attribute-level documentation
Resolving what the rules cannot
Some matches are too close to call automatically. Stewardship is the queue, the people and the service levels that resolve them, plus the audit trail showing who changed what. We configure the workflows, size the queue from real match results and train the stewards.
- Review and approval queues
- Audit trail and change history
- Steward training on real cases

We have written about each of these in more depth: types of matching in MDM, survivorship in MDM and the golden record, and our data stewardship service.
07
What an MDM implementation covers
Source and data profiling
We profile each source for completeness, identifier quality and duplicate rates.
Model design
Entities, attributes, relationships and hierarchies designed for the questions the business needs answered, mapped to the platform's model.
Match and merge rules
Rules written, tested on labelled samples and tuned until false and missed matches sit within agreed thresholds.
Source integration
Batch and real-time integrations from each source.
Stewardship workflows
Review queues, approval steps and audit trails configured.
Downstream feeds
Golden records and cross-references delivered to CRM, ERP and the warehouse.
08
Case snapshot: patient access reporting
A specialty therapy provider rebuilt its patient access reporting by hand each cycle because identifiers did not match between sources. We built clean identifiers and an MDM structure, automated case pipelines, standardised reporting and dashboards, cutting manual work by 60 to 80 percent. For the issues we see most in pharma, read common data quality challenges in pharma MDM.
