A healthcare information network provides a global database at a central information system which is synchronized with local databases at respective healthcare provider offices. The local database are used by the healthcare providers for confirming patient and healthcare information. As patient and health plan information is added, updated or deleted from any of the local databases, files are generated to update the global database. The proposed changes to the global database are verified and the global database is modified. Modification of the global database is memorialized in a repository which is then used to produce SQL commands to update each of the local databases so that they are synchronized with the global database.
