This article presents a proposal for maintenance of the referential integrity in data integrated from relational heterogeneous databases stored in XML materialized views. The central idea is the creation of a repository of rules that will have to be observed to if carrying through any operation of update in the mediating layer of a system for integration of heterogeneous relational sources of data to guarantee that the updates carried through in the data stored in this layer can be propagated to the relational databases that are part of the system integrated without causing problem of referential integrity in the same ones. This proposal has as main objective to specify a mechanism capable to guarantee that the data after exported from the relational heterogeneous databases in a mediating layer continue respecting the same integrity which these were submitted in the origin databases.
