Programming Data Access in .NET
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.
Course Objectives
To teach students how to use ADO.NET to access data from Visual Basic.NET applications and Web Services. Students will learn the pros and cons of the various mechanisms ADO.NET exposes for accessing and modifying data.
Skills Gained
Describe ADO.NET architecture ADO.NET and XML.
Build a DataSet, populate with data, and modify programmatically.
Use XML techniques while working with DataSets.
Build a Web service to query and update a data source.

If you are a logical thinker and have a passion for finding new ways of solving problems, you might want to consider a career Microsoft .NET programmer.

The .NET framework was launched by Microsoft in 2002 and has since become one of the most widely-used and sought-after programming platforms available.

This course provides students with the knowledge and skills to access and modify data by using ADO.NET 3.5.

Who Should Attend:
This course is intended for application developers who know how to create applications in Visual Studio 2005 or 2008.

At Course Completion:
After completing this course, students will be able to: - Describe the purpose and structure of ADO.NET 3.5. - Explain the role of data providers in ADO.NET 3.5. - List the technologies and techniques available for managing data with ADO.NET 3.5. - Insert, update, and delete data by using ADO.NET Command objects. - Implement transactions to control data integrity and concurrency. - Define and use a DataSet for retrieving data. - Use a DataSet to update a database. - Use a DataSet as a local cache in an occasionally connected environment. - Define LINQ queries for selecting data from an in-memory data structure. - Use LINQ to SQL to query data in a database. - Use LINQ to SQL to modify data and save changes to the database. - Explain how to use the ADO.NET Entity Framework to map a database schema to a logical business model. - Use the ADO.NET Entity Framework to query and manage data. - Explain how Synchronization Services supports occasionally-connected solutions. - Use Synchronization Services to download data from a SQL Server database. - Use Synchronization Services to upload data to a SQL Server database.
