VISUALIZATION METHOD, DEVICE AND SYSTEM FOR GLOBAL TASK NODE DEPENDENCE RELATIONSHIP

摘要

A visualization method, device and system for a global task node dependence relationship, which relates to the technical field of computers. The method comprises: initiating a task presentation request, the task presentation request comprising an identifier of a current task node (110); according to the identifier of the current task node in the task presentation request and taking the current task node as a starting point, recursively searching an upstream dependent task node and a downstream dependent task node respectively, wherein, in the recursion process, state data and a dependence relationship of the current task node, the upstream dependent task node and the downstream dependent task node are acquired (120); and on the basis of the state data and the dependence relationship of the task nodes, obtaining a global relationship tree through rendering and presenting the global relationship tree (130). The method saves on user operating steps, and due to a comprehensive dependence relationship of a current stage, the method can present upstream and downstream dependence relationships of the current task node at the same time, which facilitates the unified management by the user of tasks deployed thereby.
