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.

Preface

Chapter 11. Defining the ETL/ELT

Extraction, Transformation, and Loading or Extraction, Loading, and Transformation tools are very common on the market. Implementing a business intelligence and data warehouse project without using one of these tools is highly unlikely as they offer so many benefits. However, just because you implement one of these tools does not mean that there are some areas which are overlooked and not included in the framework. This chapter outlines some of those areas that are often overlooked but are essential within your ETL/ELT framework. The following recipes focus on building the key framework components to be included in each ETL/ELT mapping or process:

  • Abstracting your source system

  • Separating your extraction from your loading and transforming routines

  • Adding additional columns to facilitate error trapping and correction

  • Designing ETL error trapping, detection, and correction routines

  • Designing ETL data reconciliation routines

  • Designing a notification routine
