.NET Training Overview
This three-day intensive course teaches the essential elements of ADO.NET such that at the end of the course the programmer is able to utilize its tremendous database manipulation powers to build effective database applications. The course includes a major case study demonstrating the use of ADO.NET in a realistic setting. It is current to .NET 2.0, Visual Studio 2005 and SQL Server 2005.
For students pursuing MCTS certification, the course provides helpful preparation for Exam 70-526: Microsoft .NET Framework 2.0—Windows-Based Client Development.
The course opens with an overview of ADO.NET and its relation to previous Microsoft data access technologies, including ADO. It includes a discussion of ADO.NET architecture, main interfaces and classes, and programming with both the connected and disconnected models. The database for the case study is introduced.
The next two chapters cover in detail Connection and Command objects, which are essential in both connected and disconnected database access scenarios. The following chapter covers DataReaders, which provide a fast, forward-only reading capability. Programming with DataReaders bears a close resemblance to programming with the vintage recordset object.
Then the course focuses on the backbone of ADO.NET: DataSet and its related classes, such as DataAdapter, DataTable, DataRow, DataColumn, DataRelation, TableMappings and ColumnMappings. DataSet is able to handle multiple tables while remaining disconnected. It is eminently suited for building highly scalable applications for the Web.
There is a practical discussion of data binding including new features in .NET 2.0. Transactions and concurrency are covered. The course concludes with a hands-on treatment of additional new ADO.NET features in .NET 2.0.
.NET Training Learning Objectives
- Understand the architecture and main classes of ADO.NET
- Gain fluency in programming ADO.NET using C#
- Gain a thorough understanding of the use of disconnected DataSets for building highly scalable applications
- Learn how to use new features in ADO.NET 2.0 with Visual Studio 2005 and SQL Server 2005
- Implement a realistic case study that ties together all the concepts of ADO.NET in a practical demonstration
.NET Training Prerequisites
A basic knowledge of SQL and of programming the .NET Framework using C#. To get full benefit from the case studies in the course the student should be able to write simple Windows Forms applications. A working knowledge of SQL Server is also desirable.
