Programming with ADO .NET

Target Audience
This course is designed for the professional platform developer and will teach developers to build data-centric, applications and Web Services with ADO .NET, SQL Server 2000 and the Microsoft .NET Framework

Pre-Requisites
Before attending this course, students must have the following pre-requisites:Understanding of relational database concepts: table, row, column, primary keys, foreign keys, constraints, and viewsData query and modification experience, including experience with SELECT, INSERT, UPDATE, and DELETE commandsExposure to XML documents, style sheets, and schemasExperience with Visual Basic .NET, Visual Basic for Applications, or previous versions of Visual BasicExperience building user interfaces, including Web applications or Microsoft Windows applications

Purpose
At the end of 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; 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.
