Implementing an effective data model
2 Tasks

Scenario
The Delivery Service team is currently in the design phase of their project and their first task is to review the current set of enterprise-level data classes developed by the MDC Center of Excellence (COE) team. The goal of this task is to identify which data classes the Delivery Service team can reuse in their design. During their analysis, the Delivery Service team may discover data classes that the MDC COE team has not defined.
In such cases, the Delivery Service team must decide whether those undefined data classes are worthy of being defined at the enterprise level or, instead, be owned by the Delivery Service team. This decision should be based on factors such as the scope of the data class, its potential reuse across the enterprise, and the level of effort required to define and maintain the data class.
If the data class is deemed to have enterprise-level significance, the Delivery Service team should work with the MDC COE team to define the data class and ensure that it is added to the enterprise-level data model. On the other hand, if the data class is specific to the Delivery Service team's project, it should be owned by the Delivery Service team and defined as part of their project's data model.
Overall, the Delivery Service team's analysis of the enterprise-level data classes developed by the MDC COE team is an important step in ensuring that their project is aligned with the enterprise-level data model and that data is managed consistently across the organization.

Detailed Tasks
1 Analyze the MDC enterprise data model
- A business partner has a contact, addresses, and an invoice.
- A truck vendor has a contact, addresses, truck service, and a truck.
- A delivery request has a pickup, delivery address, and an invoice.
- A truck request has an invoice.
- An invoice has a contact associated with it.
| Class | Description | |
|---|---|---|
| MDC-Data-Contact | Contact of Business partner, Vendor | |
| MDC-Data-Address | Address of Business partner, Vendor, Pickup, and delivery addresses are stored in this data type | |
|

2 Complete the following assignments
The data model's definition here includes the data model for each case type, not just Data- class-extending data types.
For each data model class, you must show:
- The full class name and what class is extended
- Whether the class is abstract or concrete
- If concrete, the class shows the schema in which instances are persisted
- Properties used for data relationships
- Say embedded or, if a reference. add Ref to the property name
- Say list if something is a list
- Critical scalar properties
Note: An Interaction Diagram can help to gain a better perspective of the problem domain, especially the timing of inputs received by the system.
