Introduction

This three-day instructor-led workshop provides database developers working in enterprise environments using Microsoft SQL Server 2005 the knowledge and skills to evaluate and improve queries and query response times. The workshop focuses on systematic identification and optimization of database factors that impact query performance .

Pre-Requisites

Before attending this course, students must:

• Understand data storage (row layout, fixed length field placement and varying length field placement).
• Be familiar with index structures and index utilization.
• Have had three years of experience as a full-time database developer.
• Have complete knowledge of the locking model.
• Completely understand Transact-SQL syntax and programming logic.
• Be able to design a database to third normal form (3NF) and know the trade offs when backing out of the fully normalized design (denormalization) and designing for performance and business requirements.
• Have strong monitoring and troubleshooting skills, including using monitoring tools.
• Have basic knowledge of the operating system, platform, and application architecture.
• Know how to use a data modeling tool.
• Be familiar with SQL Server 2005 features, tools, and technologies.
