Embodiment Construction

[0030] Embodiments of the present invention provide a centralized dependency table to store dependency information about all nodes in a mesh system. When a user activates, modifies, or deletes a node or domain element, the system can search for dependency information about the target element and its related elements in the centralized dependency table. Because dependency information is kept centrally in one table, dependency checking is simplified and efficiency improved.

Abstract

A centralized dependency management table for saving the dependency information about all nodes in a netlike data management system. When a user activates, modifies or deletes one node, the system will search the centralized dependency table for the dependency information about the target node and its related nodes. The system will determine whether it is necessary to check the dependency relationship or fields of a node according to the dependency relationships, and will determine whether a maintenance operation is allowed accordingly.

Description

technical field [0001] The invention relates to data management, in particular to centralized management of data nodes. Background technique [0002] In some data management systems, data is managed as nodes in a netlike structure. In a mesh system, a node in a data structure can be linked to one or more other nodes, and the linkage that couples two nodes represents the dependency relationship between them. Different types of dependencies can be specified, and each dependency imposes certain constraints on the data management system. Therefore, before the data management system activates, updates or deletes the target node, it must identify (identify) the nodes related to the target node, and determine whether the intended operation will be allowed from the dependency relationship between the target node and its related nodes . [0003] Consider some examples of nodes and possible dependencies among these nodes in a mesh system, where each node in the system represents a ...
