A method and an apparatus for constructing a resultant database from a first database and a second database wherein data to appear in the resultant database is present in modified form in the first and second databases. A user selects from the first database at least one construction property to be used in constructing the resultant database wherein there is partial congruence of the at least one construction property between the first, second and resultant databases and from the first and second databases at least two modeling properties wherein there is partial congruence of the at least two modeling properties between the first, second and resultant databases. An inclusion probability processor assigns an inclusion probability, to each one of the data records of the first database containing the selected construction and modeling properties. A modeling processor constructs the modeling properties of the second database and models and compares the modeled modeling properties of the first database against the constructed modeling properties of the second database, and adjusts the inclusion probability of each of the data records of the first database in accordance with the comparison until an acceptable match is achieved between all the modeling properties of the first and second databases. A data record construction processor constructs resultant data records from the finally selected data records of the first database using the final inclusion probabilities with a probabilistic assignment.
