- 4. SAP NetWeaver Gateway Service Builder The SAP NetWeaver Gateway Service Builder provides a tool to centrally display and create the definition of an OData Service. Runtime artifacts (model provider class, data provider class, model and service) OData artifacts (entity set, entity type and properties) Used data sources and models Models can be created based on EDMX-Modeling. The modeling environment follows a project based approach, all relevant data is consolidated in this projects. © 2012 SAP AG. All rights reserved. 4

- 7. Entity Data Model – Overview An Entity Data Model (EDM) describes the organisation and relationship of the data resources within a particular business scenario. Entity Sets are instances of entity types and can be accessed as follows: • http://<host>/<ServiceRoot>/SalesOrderItems • http://<host>/<ServiceRoot>/<Products At least one property must be nominated as a key field Entity Type: EDM basic building block. Represents specific business object An Entity Type is built from one or more properties Navigation implements an association © 2012 SAP AG. All rights reserved. Association: Relationship between two entity types 7
