Data mapping in a data warehouse is the process of creating a link
between two distinct data models' (source and target)
tables/attributes. Data mapping is required at many stages of DW
life-cycle to help save processor overhead; every stage has its own
unique requirements and challenges. Therefore, many data warehouse
professionals want to learn data mapping in order to move from an
ETL (extract, transform, and load data between databases) developer
to a data modeler role. Data Mapping for Data Warehouse Design
provides basic and advanced knowledge about business intelligence
and data warehouse concepts including real life scenarios that
apply the standard techniques to projects across various domains.
After reading this book, readers will understand the importance of
data mapping across the data warehouse life cycle.
