Agenda
Example of a rich data model
The same data scope based on a poor data model
How to transform a rich data model into a MDM repository?
Derivation rules from rich data model to logical data model
A rich data model
Semantic modeling
- A Product is sold in many Territory sales- A Territory sales can sell many Products
- A Party plays a Role towards a Product- Role = Owner, Buyer, Customer, Provider, Lawyer, etc.
- Roles that a Party can play towards Product are limited to the subset of Roles defined with the association 'can play'
- A Costs structure can be divided into one to many other Costs structures- A Product is made within a number of Plants depending on the Country
- The color of a Product is inherited from its Family's color- The color of a Family is inherited from its Category's color
- Depending on the Product's state => modification of attributes are permitted or not- Changing the state value of a Product must be compliant with the state machine- Launching an operation on a Product must be compliant with the current state value
The state machine of Product
Alignment of the Product class with its state machine
Derivation into thelogical data model
How to keep the semantic?
How to keep the semantic - Multivalued foreign keys
How to keep the semantic - Inherited attribute
How to keep the semantic - Business rules
How to keep the semantic - Adaptative cardinality links and states management
Same data scope based on a poor data model
Namely a pure relational approach
MDM anti-patterns
When a MDM is able to manage poor data models only, then the MDM failure zone cannot be avoided
When a MDM is able to manage rich data models, it enforces a sustainable, agile and reliable MDM, avoiding the MDM failure zone
