Systems and methods for foreign key identification are described. In one embodiment, the method includes computing a threshold value for each of a primary key-foreign key (PK-FK) pair of a super-set of PK-FK, and generating a sub-set of PK-FK pair based on comparison of the threshold value and a predefined threshold value, where the predefined threshold value is indicative of an acceptance criterion. Further, the method includes determining a conformance score for each of the PK-FK pair of the subset of PK-FK pair, wherein the conformance score is based on deviations between Cumulative Probability Distribution (CPD) values of PK and CPD of FK for each PK-FK pair. Further comparing the conformance score of the each PK-FK pair of the sub-set of PK-FK pairs with a predetermined acceptability index, where the predetermined acceptability index is indicative of an acceptance of at least one positive FK from the set of PK-FK pairs. |
