ABSTRACT:
An aspect of the present invention performs offline validation of data in database system for foreign key constraints. In an embodiment, a foreign key constraint defined for a database system is identified and an SQL script designed to verify whether data values stored in a foreign key column of a detail table is present in a primary key column of a master table (corresponding to the identified foreign key constraint), is generated. The SQL script is executed to determine whether the data stored in the database system satisfies the identified foreign key constraint.
