Programming with ADO .Net

Introduction
This course will teach developers to builddata-centric applications and Web services with Microsoft ADO.NET, Microsoft SQLServer 2000, and the Microsoft .NET Framework.

Audience
This course is designed for the professionalplatform developer who is responsible for designing and building data-centric,distributed applications for his or her organization. It is designed fordevelopers who have component and Web application development skills, and whohave previously built solutions by using Microsoft Visual Studio®.
Typically, these individuals will have thefollowing skills: Experience with a .NET language such as Microsoft VisualBasic® .NET, Microsoft Visual C# , or Microsoft Visual C++®; an understandingof object-oriented concepts and terminology; experience developing distributedapplications; and experience developing Web-based applications hosted onInternet Information Server.

At Course Completion
After completing the course, students will be ableto:

Describe data-centric applications, ADO.NET architecture, and ADO.NET and XML.

Connect to SQL Server and other data sources.

Perform connected database operations including executing SELECT commands, database definition commands, dynamic SQL commands, and commands that return data from a SQL Server database in XML.

Build a DataSet schema, populate it with data, and modify the data programmatically.

Build a DataSet from an existing data source.

Use XML techniques while working with DataSets, including mapping tables and columns, creating XSD schemas, building strongly typed DataSets, and interacting with XMLDataDocuments.

Build a Web service that uses ADO.NET to query and update a data source.

Troubleshoot errors within an ADO.NET application.

Prerequisites
The course assumes that students have thefollowing skills:

Understanding of relational database concepts: table, row, column, primary keys, foreign keys, constraints, and views

Data query and modification experience, including experience with SELECT, INSERT, UPDATE, and DELETE commands

Exposure to XML documents, style sheets, and schemas

Experience with Visual Basic .NET, Visual Basic for Applications, or previous versions of Visual Basic

Experience building user interfaces, including Web applications or Microsoft Windows® applications
