Programming with Microsoft ADO.NET

Introduction

This course will teach developers to build data-centric applications and Web services with Microsoft ADO.NET, Microsoft SQL Server™ 2000, and the Microsoft .NET Framework.

Audience

This course is designed for the professional platform developer who is responsible for designing and building data-centric, distributed applications for his or her organization. It is designed for developers who have component and Web application development skills, and who have previously built solutions by using Microsoft Visual Studio®.

Typically, these individuals will have the following skills: Experience with a .NET language such as Microsoft Visual Basic® .NET, Microsoft Visual C#™, or Microsoft Visual C++®; an understanding of object-oriented concepts and terminology; experience developing distributed applications; and experience developing Web-based applications hosted on Internet Information Server.

At Course Completion

After completing the course, students will be able to:

•	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 the following 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
