Most data warehouse projects fail -- and the #1 cause is a failure to implement the right data models. In this book, leading data warehouse expert William Giovanazzo details a proven software engineering methodology and world-class techniques for data modeling in any decision support environment. Unlike other books, Object-Oriented Data Warehouse Design: Building a Star Schema recognizes that "one size doesn't fit all" in data warehouse design -- and introduces a methodology that can easily be applied to any organization's realities. Readers will develop a star schema data model from start to finish, addressing key issues such as granularity and precision; dimensions; hierarchies, and sizing. Every step is introduced with theory and supported with a live case study example. The book includes methodology checklists, chapter review questions, glossaries, bibliographies, and more. For data warehouse designers and developers, and for DBAs and system engineers in companies developing a data warehouse.show more
