In this paper we address the problem of data consistency between interrelated data. In industrial environments, lack of consistent data creates difficulties in interoperation between systems and often requires manual interventions to restart operations that fail due to inconsistent data. We report the results of a study to understand applicability, adequacy and advantages of a framework we had proposed earlier to specify interdatabase dependencies in multidatabase environments. We studied several existing Bellcore systems and identified examples of interdependent data. The examples demonstrate that the framework allows precise and detailed specification of complex interdependencies that lead to efficient strategies to enforce the consistency requirements among the corporate data managed in multiple databases. We believe that our specification framework can help in the maintenance of data that meet a business's consistency needs, reduce time consuming and costly manual operations, and provide data of better quality to end users.
