Front Cover -- Data Mapping for Data Warehouse Design -- Copyright Page -- Dedication -- Contents -- 1 Introduction -- Definition -- 2 Data Mapping Stages -- Mapping from the Source to the Data Warehouse Landing Area -- Mapping fromthe Landing Area to the Staging Database -- Mapping from the Staging Database to the Load Ready or Target Database -- Mapping from Logical Data Model to the Semantic or Access Layer -- 3 Data Mapping Types -- Logical Data Mapping -- Physical Data Mapping -- 4 Data Models -- Definition -- Entity -- Relationship -- Attributes -- Normalized Data Model.

Data mapping in data warehouse lifecycle is the process of creating a link between two distinct data models' (source and target) tables/attributes. It is required at many stages of DW life-cycle to transform data from one state to another; every stage has its own unique requirements and challenges. This book provides basic and advanced knowledge about data mapping/data transformation. It contains real life scenarios that readers face and presents solutions/standard techniques across various domains. --
