Chapter 24. The DataColumn Class

The DataColumn class defines the schema for a column in a DataTable . This schema defines the type of data that can be stored in the column, whether that data can be updated, any unique constraints on the data, and how values should be generated for new rows added to the table. Columns can be based on expressions that define a calculation or an aggregation for a column value.

As with all disconnected data classes, the DataColumn isn't specific to any data provider
