Description

Schema element: ReportingData

The schema for the reporting data in the ProjectData service.

Child elements

The Assignment_Resource_Resource_Assignments association element contains two End elements that represent opposite ends of the association. The Role attribute is a lookup key that enables a navigational property to specify the direction in the association. The Multiplicity attribute refers to the entity type. Multiplicity indicates the number of entities that can be related at each end of the association: zero or one (0..1), or many (*). The Microsoft .NET implementation of OData uses 0..1 when the navigational property points to a single entity, rather than to an entity set.

There can be many assignments that correspond to a resource.

Resource_Assignments

EntityType element: Resource

Remarks

One end of the association is the Assignment entity, and the other end is the Resource entity. The Assignment entity type contains the Resource navigation property, where the FromRole defines Assignment_Resource as the start of the association to get the collection of assignments that are associated with a resource. Similarly, the Resource entity type contains the Assignments navigation property, where the FromRole defines Resource_Assignments as the start of the association to get the resource that is associated with a collection of assignments.
