XML Schemas and Data

Visual Studio .NET 2003

XML plays a large role in the way data is handled in Visual Studio .NET. XML is used in the following ways:

  • Datasets can serialize their data as XML. The schema of a dataset — what tables, columns, data types, and constraints are in the dataset — is defined using an XML Schema (.xsd file).
  • You can infer XML Schemas from existing datasets and create datasets from existing XML Schemas.

Visual Studio makes working with XML files, XML Schemas, and ADO.NET datasets easy by providing you with a visual tool, the XML Designer.

The XML Designer is used to create and edit XML Schema files, ADO.NET datasets, XML data files, and XML source code. The XML Designer has three views:

  • Schema view for visually editing XML Schemas and ADO.NET datasets.
  • Data view with a structured data grid for visually editing XML data files.
  • XML view with color-coding, IntelliSense, and statement completion for working directly with XML source code.
