Unisys Data Exchange Development Workbench (DDW) is one of the main components of the Data Exchange product. The DDW is an independent component that can be installed on a standalone Windows machine. It provides a user-friendly graphic user interface to perform various operations.
The DDW maintains a repository of database schemas loaded from various Database Management Systems (DBMS). It enables you to define mappings from a transformation source schema to a transformation target schema. The transformation is then stored as an XML file. It also enables you to deploy the transformations to the Data Exchange Runtime Administrative service.
