Choose model scope from shared meanings and ownership, then preserve explicit interchange boundaries where contexts differ. Keep the model useful through hands-on collaboration between domain experts, modelers and implementers.

- Certification: Salesforce MuleSoft Platform Architect
- Exam section: Designing APIs using System, Process, and Experience Layers

**Official exam objective:**

> Recommend the use of an Enterprise Data Model or Bounded Context Data Models based on a set of APIs and specific preferences and organizational characteristics.

## What the exam expects

- Select a shared enterprise model or bounded-context models from organizational semantics.
- Avoid equating API count with the number of domain models.
- Preserve application independence and explicit translation boundaries.
- Organize reusable core definitions and scoped industry extensions.

An **enterprise data model** provides common business definitions across its agreed enterprise scope; a **bounded context** bounds a model's applicability; an **interchange language** carries information between models; **translation** relates representations; a **vertical extension** adds industry-specific types around reusable core definitions.

## Key facts

| Fact | Detail | Source |
|---|---|---|
| Enterprise scope | Common meanings and workable shared ownership support a common model. | [CIM](https://docs.mulesoft.com/accelerators-cim/latest/), [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |
| Context scope | Different valid models can communicate without becoming identical. | [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |
| API count | Endpoint count alone does not define model boundaries. | [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |
| Application independence | A vendor's detailed native schema is not automatically a canonical enterprise model. | [CIM](https://docs.mulesoft.com/accelerators-cim/latest/) |
| Core and extension | Industry libraries can extend or aggregate reusable core definitions. | [CIM](https://docs.mulesoft.com/accelerators-cim/latest/) |
| Published Language | Document an interchange and translate each internal model. | [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |
| Unusual consumer | A one-off translator can preserve a coherent shared protocol. | [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |
| Separate Ways | Avoid integration where no significant relationship warrants it. | [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |
| Hands-on modeling | Technical model contributors spend some time touching implementation. | [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |
| Domain refactoring | New business insight can motivate iterative model refinement. | [DDD](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf) |

## Check yourself

- Why can isolating a technical modeler from implementation produce an impractical model?
- When a new domain insight motivates refactoring, what collaboration supports the iterative refinement?
- How can a rigid division between experienced designers and implementers hinder model-driven development?
