Microsoft Course 2783 - Designing the Data Tier for Microsoft SQL Server 2005 — A 1-Day Course

 Open Public Course Closed In-House Course

Course Synopsis

This one-day instructor-led clinic provides students with the knowledge and skills to design the data tier for Microsoft SQL ServerT 2005. The clinic focuses on teaching database developers working in enterprise environments to understand and decide how application developers are going to access and consume their data. This is a major failure point of database solutions today.

Course Objectives

On completion of this course, delegates should be able to:

• Choose data access technologies and an object model to support an organization's business needs
• Design an exception handling strategy
• Choose a cursor strategy
• Design query strategies using Multiple Active Result Sets (MARS)
• Design caching strategies for database applications
• Design a scalable data tier for database applications

Intended Audience

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

Course Prerequisites

Before attending this course, students should have the following prerequisites:

• Have experience reading user requirements and business-need documents. For example, development project vision/mission statements or business analysis reports
• Have basic knowledge of the Microsoft .NET Framework, .NET concepts, ADO.NET, and service oriented architecture (SOA)
• Be familiar with the tasks that application developers typically perform
• Understand Transact-SQL syntax and programming logic
• Have some experience with professional-level database design and know the tradeoffs 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 basic monitoring and troubleshooting skills. Specifically, how to use SQL Profiler and dynamic management views
• 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
• In addition, it is recommended, but not required, that students have completed:
  • Course 2778: Writing Queries Using Microsoft SQL Server 2005 Transact-SQL
  • Course 2779: Implementing a Microsoft SQL Server 2005 Database
  • Course 2780: Maintaining a Microsoft SQL Server 2005 Database
