SQL Server 2005: MCITP Developer: Designing Databases

About this class

This two-day instructor-led course provides students with the knowledge and skills to design databases for Microsoft SQL ServerT 2005 using business requirements to guide their decisions (beyond structured third normal form [3NF] modeling techniques). Students will also learn to incorporate security requirements throughout their design.

Who will the lesson benefit?

This course 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.

What delegates will learn

After completing this course, students will be able to:

• Approach database design from a systematic perspective, gather database requirements, and formulate a conceptual design.
• Analyze and evaluate a logical database design.
• Apply best practices for creating a physical database design.
• Apply best practices when designing for database scalability.
• Design a database access strategy.
• Use best practices to model database dependencies.

What prerequisites are required

Before attending this course, students must:

• Have experience reading user requirements and business-need documents. For example, development project vision/mission statements or business analysis reports.
• Have experience reading and drawing business process flow charts.
• Have experience reading and drawing entity relationship (ER) diagrams.
• Understand Transact-SQL syntax and programming logic.
• Be able to design a database to 3NF 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.
• 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.

Contents of this class

Module 1: Approaching Database Design Systematically

This module explains how to acquire the skills to approach database design with a systematic perspective.

After completing this module, students will be able to:

• Apply a systematic approach to database design.
• Devise an appropriate strategy for gathering database requirements for a specified project.
• Formulate requirements into a conceptual model that serves as a basis for defining entities, attributes, and relationships.

Module 2: Modeling a Database at the Logical Level

This module explains the best practices followed when you build a new logical database model. You will also learn the guidelines for normalization when designing an OLTP model and when designing a data warehouse database. Finally, you will learn to evaluate the existing logical model of a database.

Lessons

• Building a Logical Database Model
• Designing for OLTP Activity
• Designing for Data Warehousing
• Evaluating Logical Models

Lab 2: Modeling a Database at the Logical Level

• Determine Entities, Attributes, Relationships, Keys, and Constraints
• Normalization and Schema Assignment

After completing this module, students will be able to:

• Apply best practices to the task of building a new logical database model.
• Apply guidelines for normalization when designing an OLTP model.
• Apply guidelines for designing a data warehouse database.
• Evaluate an existing logical model of a database.

Module 3: Modeling a Database at the Physical Level

This module explains the guidelines to be followed when designing physical database objects and constraints. The module also covers the best practices for designing database security and for designing database and server options. Finally, this module covers the best practices for evaluating the physical model.

Lessons

• Designing Physical Database Objects
• Designing Constraints
• Designing for Database Security
• Designing Server and Database Options
• Evaluating the Physical Model

Lab 3: Modeling a Database at the Physical Level
