Planning changes to the base data model

Before proceeding to modify the base data model, Guidewire strongly recommends that you first review the Data Dictionary. Verify that the existing data model does not provide the functionality that you need first before modifying the base application functionality.

Warning: Do not directly modify the physical database that PolicyCenter uses. Make changes to the PolicyCenter data model only through Guidewire Studio. The PolicyCenter database will report errors upon upgrade if it cannot synchronize the base database schema in the upgrade version with the data model in the existing version.
