Data Model

In Microsoft Dynamics AX 2012, the services framework is enhanced to use
several of the infrastructure features added in Microsoft Dynamics AX. Each
document service is built on top of a query that is used to produce the data
contract for that service as a document. The services framework handles
scenarios to produce a usable data contract schema. These scenarios include the
following:

• Replaces a surrogate foreign key with the natural key for a specific
table relationship so that the final service contract has user-friendly
readable fields instead of Surrogate Foreign Keys (SFK).

• Handles all queries that contain the Global Address Book (GAB)
views as one of their data sources.

• Handles the queries that contain tables with dimension columns in
the data sources. The framework has support to serialize or
deserialize the dimension columns across the service boundary.

• Create and update document service wizards are updated to generate
code that includes the previous changes.

• Understands table inheritance.

• Handles tables with date effective fields.
