Abstract

The invention discloses a user view-oriented process dependency relationship analysis method. The How original information of data is detailed or abstracted according to a workflow execution flow to meet the requirements of different users on different levels of How original information of the data, and the analysis of a process dependency relationship is completed by specifically utilizing detailing operation and synthesis operation. The method is characterized by comprising the following steps of (1) giving a process dependency relationship analysis model; (2) designing a process dependency relationship analysis method, and constructing a set of rule based on the workflow execution flow, the detailing operation and the synthesis operation to complete the analysis of a dependency relationship, among different levels, of the process; (3) implementing a user view based on the analysis of the process dependency relationship. According to the method, the requirements of different users on different abstraction levels of How original information can be met by fully considering different user requirements.

Description

technical field [0001] The present invention relates to the field of data origin tracking, and more specifically, relates to the field of How origin query of data. It proposes a user-view-oriented process dependency analysis method, and specifically completes the design of the data How origin dependency analysis model. Analyzing the process dependencies through the optimization operation and synthesis operation, realizing the user view of different user needs. The process dependency analysis method proposed by the present invention can meet the needs of different users for querying the How source information of data at different levels of abstraction. Background technique [0002] Data provenance is information on the entire history of data processing, including the origin of the data and all subsequent processes for processing those data. In data origin, the data processing flow is the How origin. The data process dependency is essentially the semantic information of the ...
