The invention relates to a
data quality inspection method capable of dynamically expanding, which can dynamically add, modify and delete a
data quality inspection rule, dynamically store
database connection information and the quality inspection rule in a
database, and obtain the
database connection information and the quality inspection rule from the database in real time when the quality inspection is executed; the execution process of quality inspection is dynamically scheduled according to a frequency defined by a user, and comprises the following steps: realizing a quality inspection rule
management system, performing the quality inspection execution process: performing timed task scheduling, acquiring a quality inspection rule, connecting a database, executing
data query, executing quality inspection logic and storing a quality inspection result, and performing the quality inspection result
processing process: performing
anomaly detection, generating a quality inspection report and sending the report. The problem that a traditional
data quality inspection
system is insufficient in rule expansibility, complex rule support, database type adaptability and
exception handling efficiency is solved, and
quality monitoring and
verification of large-scale and multi-source heterogeneous data are achieved by dynamically registering database links and quality inspection rules and combining complex
expression analysis.
