A structured data management system which provides services concerning a structured electronic data object. In this system, a structured data storage unit stores a plurality of structured data objects associated with each other. Each structured data object can be represented as a tree structure constructed by a plurality of data elements, or nodes. Further, the individual nodes of a tree structure are associated with their respective process scripts. Through an input/output interface unit, a message addressed to a certain destination node arrives. Upon receipt of the message, a structured data processing unit identifies the destination node by tracing the tree structure of a particular structured data object where the destination node resides. The structured data processing unit then executes a process script associated with the destination node being identified. During the execution of this process script, the structured data processing unit may encounter another message that is addressed to a node in a different structured data object. In this case, the structured data processing unit reads out the specified object from the structured data storage unit and executes a process script of that node.
