Using Analytical Modelling To Ensure Application Performance

Analytical modelling is a technique to determine future computer system performance. It has been used for years by capacity planners and performance specialists. Analytical modelling can be used by DBAs and application developers to determine their application’s performance while still in the design stage. This presentation describes analytical modelling, contrasts it with simulation and provides guidelines for obtaining timely, cost-effective estimates of application performance. Detailed technical information will be provided to instruct developers on obtaining key performance-related variables, how to build models and how to interpret modelling results. It provides specifics on application development problems and pitfalls, and how modelling can expose problems and show alternatives. The presentation will show that, with very little effort, critical design issues can be uncovered before application implementation to ensure that applications perform well when put into production.

Managing Technology as an Asset

Companies are spending more and more on new technology. But are they getting value for money? And are they effectively managing the technology that they already have? According to the Gartner Group, “By 1998, asset management will grow in complexity and become the most important issue for information technology managers.” We are pleased to welcome Sherry Irwin of Technology Asset Management who will illuminate some of the issues involved for us in Information Resource Management.
