DATA LINEAGE IN AN INTELLIGENT DATA INTEGRATION SYSTEM

A computer-executed method includes storing in a data store data attributes, data objects, and a data analysis tool (DAT). Each data object has an attribute set and an identifier set. The method includes identifying each data object that has an attribute set comprising a data attribute matching each reference data attribute associated with the DAT, and selecting an identified data object as an input data object for the DAT. The DAT generates a new data object as a function of the input data object, which includes analyzing the input data object with reference to an auxiliary data object and creating an identifier set for the new data object that includes an identifier of the new data object for distinguishing the new data object from each other data object in the data store, and the identifier of the auxiliary data object. The new data object is stored in the data store.
