> 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 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
> 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.
