Hour 2. Working with DataSets and DataTables

At the heart of the ADO.NET platform, you'll find the DataSet and DataTable objects. The DataSet operates just like an in-memory database. That is to say, the DataSet object can contain multiple DataTables, along with any relationships, constraints, and primary keys necessary to closely represent the data returned from the data source.

In this hour, you will learn the following:

  • The basics of the database schema

  • How to instantiate and manipulate the basic ADO.NET objects, such as the DataSet, DataTable, and DataColumns

  • How to define the schema of a DataSet

  • How to create and configure a new ASP.NET Web
