ADO.NET Using Visual C# 2005

AUDIENCE: Developers wishing to understand the data access capabilities of the .Net Framework.
PREREQUISITES: This course assumes that students have some familiarity with Visual Studio 2005, the .NET Framework, and the fundamentals of programming with Visual C#.
DURATION: 3 days. Hands on.
OBJECTIVES: In this course, learn about the features provided by ADO.NET 2.0. Learn to connect to data sources, retrieve and manipulate data, and perform data updates. Examine the various ADO.NET classes, including Connection, Command, DataReader, DataSet, DataTable, DataRelation, and more. See how to apply constraints and relationships to disconnected data. Learn how to update data, including how to handle stored procedures, parameters, and return values. Understand how to search, sort, and filter data stored in a DataSet or DataTable. Become familiar with strongly typed DataSets and learn their advantages. See how to leverage the power of XML through serialization, Diffgrams,and the XMLDataDocument object. Examine new ADO.NET features that support SQL Server 2005 technologies, including asynchronous commands, Multiple Active Result Sets, bulk inserts , and more.
At the end of this course, delegates will be able to:
- Connect to multiple types of data sources, including SQL Server and Microsoft Jet/Access
- Retrieve data, using the DataAdapter, Command, and DataReader classes
- Create and configure Command parameters
- Cache data using the DataTable and DataSet classes
- Apply constraints to DataTable and DataColumn objects
- Create relations between DataTable objects, using the DataRelation class
- Update data using DataAdapter and Command classes
- Work with strongly typed DataSet and DataTable classes
- Retrieve and update data using TableAdapter classes
- Handle exceptions and data errors, including concurrency errors
- Search, sort, and filter data using the DataView class
- Work with auto-increment columns in multi-user applications
- Retrieve and generate XML data
- Take advantage of new SQL Server 2005 features
