Relationships in ADO.NET Datasets

A dataset can contain multiple tables, including tables that have an implicit relationship between them — tables with key fields in common. To take advantage of this implicit relationship, you use an ADO.NET DataRelation object. The following topics provide information about ADO.NET DataRelation objects, how to create them, and how to use them to work with data in related tables.
