Datasets are the result of
bringing together ADO and XML. A dataset contains one or more data of tabular
XML, known as DataTables, these data can be treated separately, or can have
relationships defined between them. Indeed these relationships give you ADO
data SHAPING without needing to master the SHAPE language, which many people
are not comfortable with.
The dataset is
disconnected in-memory cache database. The dataset object model looks like
this:
·
- Dataset
- DataTableCollection
- DataTable
- DataView
- DataRowCollection
- DataRow
-
DataColumnCollection
- DataColumn
- ChildRelations
- ParentRelations
- Constraints
- PrimaryKey
- DataRelationCollection
