Executive Summary

This is a discussion and on how to bring harmony between the data and the metadata with a presentation on how one Data Warehouse group used CA ERwin and other tools to accomplish that. This discussion will explore the use of certain ERwin Data Modeling tool features like UDP's, CA ERwin Model Manager reports, the DataWarehouse Source function and the MetaIntegration Import/Export facility to maintain certain aspects of metadata. The speaker will show how he kept track of their source to target mapping and other data lineage, the reference data Domain of Values used in translating codes into descriptions, the oversight of standard definitions for same named data columns across databases and the use of global objects within the datamart layer.
