Definition
A maintenance data model is the formal structure defining how maintenance-relevant objects (assets, work orders, failure records, spare parts) and their relationships are organized within a system: which fields exist, how objects link to one another, and what rules govern that structure. It is the schema underlying master data and transactional records, not the data itself.
Key facts
- A schema (the structure and relationships) not the data instances (assets, work orders) that populate it.
- Determines what can actually be captured and linked: a model without a field for failure mode makes that information un-recordable.
- Consistency of the model across systems (CMMS, ERP) is what enables integration rather than manual data reconciliation.
- Distinct from master data, which is the specific content held within the structure the data model defines.
How does Maintenance data model work in maintenance?
A maintenance data model defines the structural schema for maintenance information: what object types exist (asset, work order, failure record), what attributes each carries, and how objects relate to one another (a work order links to an asset, a failure record links to a work order), establishing what can be captured and queried.
What does Maintenance data model require?
Master data is the actual content (a specific asset's specifications, a specific spare part's description) populated within the structure. The maintenance data model is that underlying structure itself: the schema of object types, fields, and relationships that determines what master data and transactional data can exist and how they connect.

Frequently asked questions
How are data objects and relationships of maintenance modeled?
Through a maintenance data model: the formal schema defining which object types (assets, work orders, failure records) exist, what fields they carry, and how they relate to one another within a system.
