 What does the model layer of MuleSoft represent?

The concept of a "model layer" specific to MuleSoft 4 doesn't directly translate to its architecture. MuleSoft 4 utilizes an API-Led Connectivity (ALC) approach, which revolves around three key layers:

1. Experience API: This layer exposes APIs for consumption by external applications like mobile apps or web interfaces. It focuses on providing a user-friendly and consistent way to interact with the system.

2. Process API: This layer acts as the intermediary, orchestrating the integration logic. It interacts with system APIs to retrieve or manipulate data and can involve transformations, routing, and business logic implementation.

3. System API: This layer provides access to backend systems and data sources. It interacts with databases, legacy applications, or external services using various protocols.

Here's why there isn't a dedicated "model layer":

• Data Transformation: While traditional layered architectures might have a separate model layer for data representation, MuleSoft 4 relies on data structures within flows to handle data transformation. You can use XML, JSON, or custom Java objects to represent data as needed.

• Focus on APIs: The core principle of MuleSoft 4 is API-driven integration. Data manipulation and transformation primarily happen within flows using connectors and transformers.

So, instead of a distinct model layer, MuleSoft 4 emphasizes data management through:

• DataWeave: A powerful scripting language for data transformation and manipulation within Mule flows.

• Object Mapping: Allows you to map data between different formats like XML and JSON.

• Connectors: Provide access to various data sources and can handle data conversion during interaction.
