Introduction

The concept of application transaction (also called business transaction or an end-user transaction) is at the heart of Application Performance Management. It is a sequence of user and system activities perceived by an end-user to be a logical unit of work accomplished in any business application.

For example, in a typical ERP:

• A user logging in or out
• Applying for leave or submission of timesheet
• Executing a financial transaction

Apart from technical requirements such as performance, availability, and security, it is equally important to consider performance as seen by the end-user. Business owners and senior management are more attuned to the end-user experience for the success of the business.

End-user experience is measured by replicating Application Usage, or Load Patterns, instead of executing an individual transaction in isolation. So understanding Load Patterns is an important step in Application Performance Management.
