A computer implemented method for storing ad hoc relations between previously unrelated database objects assigned to different database structures, the method comprising the steps of: defining at least three database structures: A, B and C wherein there exists a relation between objects of structure A and objects of structure B and wherein there exists a relation between objects of structure B and objects of structure C; filtering data of structure A; accessing structure B using a selected relation between structure A and structure B; storing information about filtering of structure A and information on selected path between structure A and structure B; filtering results obtained from structure B; accessing structure C using a selected relation between structure B and structure C; storing information about filtering of structure B and information on selected path between structure B and structure C. |
