Tuning and optimizing queries using SQL Server 2005

Intended for

This course is intended for current professional database developers who have several years of on-the-job experience developing SQL Server database solutions in an enterprise environment.

Background

Before attending this course, students must have working knowledge with SQL Server, being for instance a MS Certified Technology Specialist for SQL Server. Having attended the following courses is strongly recommended:

Knowledge of data base design techniques (normalization to 3NF). Basic knowledge of the operating system and application architectures. Good knowledge of Transact-SQL (cursors, grouping, joins, subqueries, ...) is required.

Training method

This instructor-led workshop makes use of the official Microsoft course handouts. A lot of time is spent on hands-on exercises (about 75% of the time).

Course leader

RealDolmen.

Duration

3 days.

Schedule

No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested ? Please contact ABIS.
