Salvaging information engineering techniques in the data warehouse environment

Abstract

The art of Information Engineering (IE) continuously evolves and, by today's standards, is considered an integral function in most any organization. Strategic planning teams weave methodologies, which are integrated to process information, the goal being to sort, store, and retrieve useful data. The following article will describe three techniques that can utilize existing information engineering in a data warehouse project. First, the entity relationship diagram and its use in a three phase data model approach. Second, the functional decomposition diagram and its use in segmenting and defining key performance indicators and dimensions. Third, creating a modified CRUD (Create, Read, Update and Delete) matrix that deals with logical entities and current systems.
