You can synchronize all physical data objects. When you synchronize relational data objects or customized data objects, you can retain or overwrite the key relationships you define in the Developer tool.

You can configure a customized data object to be synchronized when its sources change. For example, a customized data object uses a relational data object as a source, and you add a column to the relational data object. The Developer tool adds the column to the customized data object. To synchronize a customized data object when its sources change, select the

Synchronize input and output

option in the

Overview

properties of the customized data object.

To synchronize any physical data object, right-click the object in the

Object Explorer

view, and select

Synchronize
