Business Intelligence Cookbook: A Project Lifecycle Approach Using Oracle Technology

By: John Heaton

Overview of this book

Oracle Database 11g is a comprehensive database platform for data warehousing and business intelligence that combines industry-leading scalability and performance, deeply-integrated analytics, and embedded integration and data-quality all in a single platform running on a reliable, low-cost grid infrastructure. This book steps through the lifecycle of building a data warehouse with key tips and techniques along the way. Business Intelligence Cookbook: A Project Lifecycle Approach Using Oracle Technology outlines the key ways to effectively use Oracle technology to deliver your business intelligence solution. This is a practical guide starting with key recipes for project management then moving onto project delivery. Business Intelligence Cookbook: A Project Lifecycle Approach Using Oracle Technology is a practical guide for performing key steps and functions on your project. This book starts with setting the foundation for a highly repeatable efficient project management approach by assessing your current methodology to see how suitable it is for a business intelligence program. We also learn to set up the project delivery phases to consistently estimate the effort for a project. Along the way we learn to create blueprints for the business intelligence solution that help to connect and map out the destination of the solution. We then move on to analyze requirements, sources, and data. Finally we learn to secure the data as it is an important asset within the organization and needs to be secured efficiently and effectively.

Selecting the Third Normal Form or a Dimensional model

Using the Third Normal Form or a Dimensional model to support your data warehouse solution is an important and highly debated decision within the industry. Primary reasons for choosing one over the other include:

  • Skills and capabilities within the organizations

  • Preferences

  • The approach to building your warehouse solution

Getting ready

Understand the differences and limitations of a Third Normal Form and or a Dimensional-modeling approach to building your warehouse. Research the technology you plan to implement, to understand which model it works more optimally with.

How to do it...

Third Normal Form modeling is normally used within Online Transaction Processing Applications (OLTP). Dimensional modeling has been refined over the years and is generally accepted for data warehouses:

  1. 1. Determine the modeling approach for the initial stage area, which houses a copy of the source. Typically, here you will mirror the source system. Note, you will...
