ADO.NET and LINQ with VB.NET

Audience

This course is intended for developers and others who need to use ADO.NET 4.0 (Visual Studio 2010) in building applications. The class is also relevant for developers using ADO.NET 3.5 (Visual Studio 2008), please advise us of which version you are using when booking.

Prerequisites

Those attending should have a basic understanding of the .NET Framework and Microsoft Visual Studio and be competent in Microsoft Visual Basic or C# if required. A basic understanding of relational databases and how they are structured and some knowledge of SQL syntax will be an advantage.

Duration

3 days. Hands on.

Course Objectives

On completion of this course delegates will:

• Have a basic introduction to databases, SQL, and ADO.NET
• Quickly be prototyping database applications using Rapid Application Development (RAD) tools like data sources.
• Learn how to build 3-layer applications the ways the pros do, with presentation, business, and database classes. This is where you'll get into ADO.NET coding to create your own database classes.
• Look at LINQ (Language-Integrated Query), a .NET feature that lets you handle all types of data using a query language that's integrated into Visual Basic and that saves you a lot of ADO.NET coding. That means you'll learn how to:
  • • Use LINQ to DataSet to query the data in typed or untyped datasets.
    • Use LINQ to SQL, which allows you to generate an object model from the objects in a SQL Server database that can then be used to access and update the database data...a feature that offers you some of the same benefits as the Entity Framework.
    • Use LINQ to XML to manipulate XML data much more easily than you can using the Document Object Model. - Use LINQ data source controls with web applications.

• Learn to work with the ADO.NET Entity Framework.  This is another way to let .NET generate the code you need and do more of the work for you. Using this feature, you create an Entity Data Model that defines a conceptual model for the business objects used by an application, a storage model for the objects in a database, and mappings that relate the two. Then:
  • •  You can use LINQ or a special form of SQL to retrieve data into the business objects. - You can work with the business objects and save changes to the database using generated code.
    • You can use Entity data source controls with web applications.
