Miller Sr. Data Warehousing For Dummies, 2nd Edition, guides you through the overwhelming amount of hype about this subject to help you get the most from data warehousing. If you regularly use computers in your job to find information and facts as a contracts analyst, researcher, district sales manager, or any one of thousands of other jobs in which data is a key asset to you and your organization, this book has in-depth information about the real business value again, without the hype that you can gain from data warehousing.
Why I Wrote This Book Although data warehousing can be an incredibly powerful tool for you and others in your organization, pitfalls a lot of them! Everyone wants to consume data — which leads directly to the need for a data warehouse!
This book is, in many ways, a consolidation of my down-to-earth, no-hype conversations with and presentations to clients, IT professionals, product engineers, architects, and many others in recent years about what data warehousing means to business organizations today and tomorrow.
If this book is your first real exposure to data warehousing terminology, concepts, and technology, you probably want to go with this method. I wrote each chapter to stand on its own, with little dependency on any other chapter. To give you a sense of what awaits you in Data Warehousing For Dummies, 2nd Edition, the following sections describe the contents of the book, which are divided into seven parts.
Introduction Part I: The Data Warehouse: Home for Your Data Assets Part I gets down to the basics of data warehousing: concepts, terminology, roots of the discipline, and what to do with a data warehouse after you build it.
Chapter 1 gets right to the point about a data warehouse: what you can expect to find there, how and where its content is formed, and some early cautions to help you avoid pitfalls that await you during your first data warehousing project. Chapter 2 describes, in business-oriented terms, exactly what a data warehouse can do for you.
I describe the different types of data warehouses that you can build small, medium, or way big!
Chapter 4 describes data marts small-scale data warehouses , which have become the preferred method to deliver data to end users. Part II: Data Warehousing Technology In Part II, you go beyond basic concepts to find out about the technology behind data warehousing, particularly database technology.
Specialized databases, such as multidimensional and column-wise or vertical databases, as well as other types of databases used for data warehousing, are described in Chapter 6. In this chapter, you can figure out which type of database is a viable option for your data warehousing project.
You can read about data warehousing middleware — software products and tools used to extract or access data from source applications and do all the necessary functions to move that data into a data warehouse — in Chapter 7, along with the issues you have to watch out for in this area. See Chapter 8 for an overview of business intelligence and what it means to data warehousing. Chapters 9 through 12 each describe, in detail, one major area of business intelligence querying and reporting, analytical processing, data mining, and dashboard and scorecards, respectively.
These chapters present you with ready-to-use advice about products in each of these areas. Part IV discusses project methodology, management techniques, the analysis of data sources, and how to work with users. Chapter 13 describes data warehouse development methodology and the similarities to and differences from the methodologies you use for other types of applications.

Find out in Chapter 14 the right way to manage a data warehouse project to maximize your chances for success. Chapters 15 through 18 each discuss an important part of a data warehouse project compiling requirements, analyzing data sources, delivering the end solution, and working with users, respectively and give you a lot of tips and tricks to use in each of these critical areas. Part V: Data Warehousing: The Big Picture This part of the book discusses the big picture: data warehousing in the context of all the other organizations and people in your IT organization and even outside consultants and your other information systems.
You can also read about how to use that information in your data warehouse. To understand how a data warehouse fits into your overall computing environment with the rest of your applications and information systems, see Chapter For an executive boardroom view of data warehousing, check out Chapter Is this discipline as high a priority to the corporate bigwigs as you might imagine, considering its popularity?
For advice about what to do if you have systems already in place that are sort of but not really like a data warehouse, and which you use for simple querying and reporting, read Chapter To replace those systems or upgrade them to a data warehouse — that is the question. Chapter 23 describes how to deal with data warehousing product vendors and the best ways to acquire information at the numerous data warehousing trade shows.
You probably have to deal with data warehousing consultants or maybe you are one.For technical support, please visit www.
Chapter 13 describes data warehouse development methodology and the similarities to and differences from the methodologies you use for other types of applications. If this book is your first real exposure to data warehousing terminology, concepts, and technology, you probably want to go with this method.

The group then goes through the list of information data assets , item by item, and figures out where the data warehouse can obtain that particular piece of data raw material. After completing the details of where the business can get each piece of information, the data warehousing team creates extraction programs.
