Entity-based service operation for object-based persistence

Abstract

Entity-based service operation upon object-based persistence, is efficiently accomplished utilizing mapping between entities and stored objects. An engine within the persistence layer receives a service call referencing an interface entity. The engine determines a context of a core object in the persistence layer. Based upon the context, the engine constructs from the core object, a prepared object including an entity node. A path between the entity node and a root node of the prepared object may comprise context, or may be derived from only partially reading the core object to construct the prepared object. The engine enriches the entity node with entity data from the service call, to generate an applied object. Referencing the applied object as a parameter, the engine executes the service call on the core object. The engine maps the core object to a result object returned to the interface layer in response to the service call.
