Module 1: Overview of Programming SQL Server
This module provides students with an overview of enterpriselevel application architecture and of Transact-SQL as a programming language. Transact-SQL is a data definition, manipulation, and control language. Students are assumed to be familiar with ANSI-SQL and basic programming concepts, such as functions, operators, variables, and control-of-flow statements. Students will also learn the different ways to execute Transact-SQL.
· Introducing SQL Server Databases
· Working With SQL Server Programming Tools
· Understanding Transact-SQL Elements
· Programming Language Elements
· Executing Transact-SQL Statements

Module 2: Creating and Managing Databases
This module describes how to create a database, set database options, create filegroups, and manage a database and the transaction log. It reviews disk space allocation and how the transaction log records data modifications.
· Defining Databases
· Using Filegroups
· Managing Databases

Module 3: Creating Data Types and Tables
This module describes how to create data types and tables and generate Transact-SQL scripts containing statements that create a database and its objects.
· Working with Data Types
· Working with Tables
· Generating Column Values
· Generating Scripts

Module 4: Implementing Data Integrity
This module shows how centrally-managed data integrity is a benefit of relational databases. Beginning with an introduction to data integrity concepts, including the methods available for enforcing data integrity, the module then introduces a section on constraints, the key method of ensuring data integrity. The module discusses the creation, implementation, and disabling of constraints and discusses how defaults and rules are an alternate way to enforce data integrity. The module concludes by comparing different data integrity methods.
· Introducing Data Integrity
· Defining Constraints
· Understanding Constraint Types
· Disabling Constraints
· Using Defaults and Rules
· Deciding Which Enforcement Method to Use

Module 5: Planning Indexes
This module provides students with an overview of planning indexes. It explains how database performance can be improved with indexes; how clustered and nonclustered indexes are stored in SQL Server and how SQL Server retrieves rows by using indexes; and explores how SQL Server maintains indexes. The module concludes with guidelines for deciding which columns to index.r /> Lessons
· Introducing Indexes
· Understanding Index Architecture
· Retrieving Stored Data with SQL Server
· Maintaining Index and Heap Structures in SQL Server
· Deciding Which Columns to Index

Module 6: Creating and Maintaining Indexes
This module provides students with an overview of using the CREATE INDEX options to create and maintain indexes. It describes how maintenance procedures physically change the indexes; discusses maintenance tools; describes the use of statistics in SQL Server; and describes ways to verify that indexes are used and whether they perform optimally. The module concludes with a discussion of when to use the Index Tuning Wizard.
· Creating Indexes
· Understanding Index Creation Options
· Maintaining Indexes

Module 7: Implementing Views
This module defines views and their advantages, showing how views provide the ability to store a predefined query as an object in the database for later use. Views also offer a convenient way to hide sensitive data and the complexities of a database design and to provide a set of information without requiring the user to write or execute Transact-SQL statements. The module describes creating views and provides examples of how to include computed columns and built-in functions in the view definitions. The module then covers restrictions on modifying data through views. The last section discusses how views can improve performance.
· Introducing Views
· Defining and Using Views
· Using Views to Optimize Performance

Module 8: Implementing Stored Procedures
This module describes how to use stored procedures to improve application design and performance by encapsulating business rules. It discusses ways to process common queries and data modifications, and provides numerous examples and demonstrations of stored procedures.
· Introducing Stored Procedures
· Creating, Modifying, Dropping, and Executing Stored Procedures

Module 9: Implementing User-Defined Functions
This module discusses the implementation of user-defined functions. It explains the three types of user-defined functions and the general syntax for creating and altering them, and provides an example of each type.
· Introducing User-Defined Functions
· Implementing User-Defined Functions

Module 10: Implementing Triggers
This module shows that triggers are useful tools for database implementers who want certain actions to be performed whenever data is inserted, updated, or deleted from a specific table. Triggers are especially useful tools for cascading changes throughout other tables in the database while preserving complex referential integrity.r /> Lessons
· Introducing Triggers
· Creating, Altering, and Dropping Triggers
· Working with Triggers
· Implementing Triggers

Module 11: Programming Across Multiple Servers
This module provides students with information on how to design security for a multi-server environment. It also explains the construction of distributed queries, distributed transactions, and partitioned views.
· Introducing Distributed Queries
· Setting Up a Linked Server Environment
· Working with Linked Servers
· Using Partitioned Views

Module 12: Optimizing Query Performance
This module provides students with an in-depth look at how the query optimizer works, how to obtain query plan information, and how to implement indexing strategies.r /> Lessons
· Introducing the Query Optimizer
· Tuning Performance Using SQL Utilities
· Using an Index to Cover a Query
· Overriding the Query Optimizer
· Understanding Indexing Strategies and Guidelines

Module 13: Performing Advance Query Analysis
This module describes how the query optimizer evaluates and processes queries that contain the AND operator, the OR operator, and join operations.
· Analyzing Queries That Use the AND and OR Operator
· Analyzing Queries That Use Join Operations

Module 14: Managing Transactions and Locks
This module discusses how transactions and locks ensure transaction integrity to accommodate multiple users. The module continues with a discussion of how transactions are executed and rolled back. A short animation helps to convey how transaction processing works. The module next describes how SQL Server locks maintain data consistency and concurrency. The module then introduces resources that can be locked, the different types of locks, and lock compatibility. A discussion follows on SQL Server dynamic locking based on schema and query. The final section describes locking options, discusses deadlocks, and explains how to display information on active locks.
· Introducing Transactions and Locks
· Managing Transactions
· Understanding SQL Server Locking Architecture
· Managing Locks
