The invention relates to the technical field of
big data and the field of financial science and technology, and discloses a
data dependency relationship confirmation method, which comprises the following steps of: importing
metadata information containing a field name, a data table name and
data source information into a
data processing module to obtain a target field name, and retrieving a target field in the
metadata information by utilizing the
data processing module to confirm a
data dependency relationship. Determining an upstream
data source and a downstream data destination of the target field; generating upstream and downstream
data link diagrams of the target field, wherein the upstream and downstream
data link diagrams are used for identifying a flow relation of data, a
data generator and
processing logic; and analyzing a dependency relationship between the target field and the upstream and downstream fields based on the
link diagram, and further determining a data table on which the target field depends and owner information of the data table. According to the method, through automatic analysis and
link diagram generation, the original complex process needing manual query and
processing is simplified, the
data dependency relationship is clearer, the communication cost and query time of developers are reduced, and the data use accuracy and
processing efficiency are effectively improved.
