Description

Introduction

The name "Kimball" is synonymous with dimensional modeling. The Kimball Group established the vocabulary and techniques for dimensional modeling, and these techniques show up in today's popular business intelligence, database, and ETL tools.

An excellent dimensional model, or star schema, is the foundation of an excellent data warehouse. This course provides the opportunity to learn the Kimball Approach of dimensional modeling. Having a great dimensional model is necessary, but not sufficient, to implementing a successful business intelligence/data warehouse system. The course also prepares you to successfully implement your business intelligence / data warehouse program by covering the essential elements of the popular Kimball Approach.

You will learn practical techniques for designing, developing, and implementing your dimensional model, from the basics to the most advanced practices. Concepts are taught through a combination of lectures, case studies, and small group exercises. Our goal is to provide you with the skillset you need to lead a dimensional modeling effort at your organization or participate in the system's successful implementation.

This course is designed for data warehouse architects, data modelers, database administrators, business analysts, and ETL or BI application developers and designers.

Joy Mundy

This course gives you the opportunity to learn directly from Joy Mundy. She co-authored, with Ralph Kimball and other members of Kimball Group, many of the popular “Toolkit” books including The Data Warehouse Lifecycle Toolkit (Second Edition), The Microsoft Data Warehouse Toolkit, and The Kimball Group Reader (Second Edition). Joy teaches the full course portfolio, previously taught by Kimball University for one simple reason: the methodology proves its value over and over in practice.

Joy Mundy has worked with business managers and IT professionals to prioritize, justify and implement large-scale business intelligence and data warehousing systems since 1992. She leverages these consulting experiences when teaching DW/BI courses. 

Joy began her career as a financial analyst, but soon decided that she enjoyed working with a wide variety of data. She learned the fundamentals of data warehousing by building a system at Stanford University, and then started a data warehouse consultancy in 1994. She worked at WebTV and Microsoft’s SQL Server product development team for a few years before returning to consulting with Kimball Group in 2004, until Kimball Group’s dissolution in 2016. Joy is now semi-retired, but loves teaching and the occasional consulting engagement. She graduated from Tufts University with a BS in Economics, and from Stanford University with an MS in Engineering-Economic Systems.
