The invention provides a data probing method and
system. The method comprises the steps of
metadata basic information probing,
metadata field security attribute probing and
metadata blood relationship probing. Null value, NULL value and non-null-duty ratio exploration, data volume and distribution exploration, field attribute and distribution exploration and security exploration are carried out;
data security analysis,
data integrity and distribution analysis, and data relationship and distribution analysis are carried out. According to the invention, through intelligent automatic analysis and identification, null values, redundant information and performance bottlenecks in data are found in real time, and accurate support is provided for subsequent
data governance; the probing task can be automatically completed only by inputting basic
database connection information and related parameters, so that the efficiency is improved, and manual intervention is reduced; the universality is high, different
database environments and data scales are adapted, and the probing process is efficient and accurate; the structure, the use condition and the
potential risk of enterprise data assets can be deeply known, so that
data management is accurate and efficient, and
digital transformation and
intelligent decision making are promoted.
