In this lesson, we revisit usage-based optimization, a subject that we undertook in my article MSAS Administration and Optimization: Simple Cube Usage Analysis, in September of 2003, and MSAS Administration and Optimization: Toward More Sophisticated Analysis in October of 2003. In the earlier articles, we discovered that, among several tools that Microsoft SQL Server 2000 Analysis Services offered us to assist in the maintenance and optimization of our cubes, two of these tools, the Usage Analysis Wizard and the Usage-Based Optimization Wizard, leveraged the usage-based optimization features of Analysis Services.
Data modeling is no doubt one of the most important and challenging aspects of developing, maintaining, augmenting and integrating typical enterprise systems. More than 90% of functionality of enterprise systems is centered round creating, manipulating and querying data.

How the software package brings value through successful implementation, is critical to the business. Internal groups as well as industry analysts will closely watch COTS package implementation in the organization.
