What we teach you

  • Measure Database Performance
  • Optimize Physical Database Design
  • Optimize Queries for Performance
  • Refactore Cursors into Queries
  • Optimize an Indexing Strategy
  • Manage Concurrency

    Required skills

  • Have working knowledge of data storage. Specifically, knowledge about row layout, fixed length field placement and varying length field placement.
  • Be familiar with index structures and index utilization. Specifically, they must understand the interaction between non-clustered indexes, clustered indexes and heaps. They must know why a covering index can improve performance.
  • Have had hands-on database developer experience. Specifically, three years of experience as a full-time database developer in an enterprise environment.
  • Be familiar with the locking model. Specifically, students should have an understanding of lock modes, lock objects and isolation levels and be familiar with process blocking.
  • Understand Transact-SQL syntax and programming logic. Specifically, students should be completely fluent in advanced queries, aggregate queries, subqueries, user-defined functions, cursors, control of flow statements, CASE expressions, and all types of joins.
  • 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 in addition to being familiar with design models, such as Star and Snowflake schemas.
  • Have strong monitoring and troubleshooting skills, including using monitoring tools.
  • Have basic knowledge of the operating system and platform. That is, how the operating system integrates with the database, what the platform or operating system can do, and how interaction between the operating system and the database works.
  • Have basic knowledge of application architecture. That is, how applications can be designed in three layers, what applications can do, how interaction between the application and the database works, and how the interaction between the database and the platform or operating system works.
  • Know how to use a data modeling tool.
  • Be familiar with SQL Server 2005 features, tools, and technologies.
  • Have a Microsoft Certified Technology Specialist: Microsoft SQL Server 2005 credential - or equivalent experience.
