Abstract
Embodiments of the disclosure provide a method, apparatus, and system for identifying data tables. The method comprises acquiring a first dependency relationship between a plurality of data tables; collecting statistics on a path length and a path number of the data tables based on the first dependency relationship; acquiring a second dependency relationship between one or more fields in the data tables; determining importance coefficients of the one or more fields based on the second dependency relationship; determining a degree of association between the data tables by using the path length, the path number, and the importance coefficients; and identifying the data tables based on the degree of association.
Claims20
A method comprising:
- acquiring a first dependency relationship between a plurality of data tables;
- collecting statistics on a path length and a path number of the data tables based on the first dependency relationship;
- acquiring a second dependency relationship between one or more fields in the data tables;
- determining importance coefficients of the one or more fields based on the second dependency relationship;
- determining a degree of association between the data tables by using the path length, the path number, and the importance coefficients;
- and
- identifying the data tables based on the degree of association.
An apparatus comprising:
- a processor;
- and
- a non-transitory memory storing computer-executable instructions therein that, when executed by the processor, cause the apparatus to perform the method of:
- acquiring a first dependency relationship between a plurality of data tables;
- collecting statistics on a path length and a path number of the data tables based on the first dependency relationship;
- acquiring a second dependency relationship between one or more fields in the data tables;
- determining importance coefficients of the one or more fields based on the second dependency relationship;
- determining a degree of association between the data tables by using the path length, the path number, and the importance coefficients;
- and
- identifying the data tables based on the degree of association.
