The S4HANA data model is defined using a collection of standard JSON documents that contain the data, identifiers, and object relationships for a given service. These documents are stored on URL endpoints that are accessible using sets of proprietary OData API calls. To expose S4HANA resources to SQL applications, the driver maps S4HANA endpoints to one schema and each schema has a set of relational parent and child tables. The following sections describe the relational tables exposed by the driver along with their corresponding S4HANA OData API call.
