Patent ID: 8452810

Claim:
A process for improving a performance of a manufacturing execution system, the manufacturing execution system depicting at least a part of a productive process to a hierarchically structured set of entities and the manufacturing execution system further having an application programming interface for managing data in a data base, the process being performed by a processor of the manufacturing execution system and comprises the steps of: providing a method accessible by means of the application programming interface, the method manipulating the hierarchically structured set of entities, the method specifying a specific behavior for each entity of a tree and the specific behavior identifying an existence or non-existence of a localized restriction preventing a global manipulation to the entity, the global manipulation allowing a manipulation of the hierarchically structured set of entities without the localized restriction in a single round trip between a client application and a server application; inputting a tree into the application programming interface, the tree representing a hierarchical relationship between at least two entities of the hierarchically structured set of entities; and manipulating at least two of the entities of the tree according to the method in dependence on the existence of the localized restriction preventing the global manipulation.
