Now that you understand the ins-and-outs of manipulating ADO.NET DataSets manually, it's time to turn your attention to the topic of data adapter objects. A data adapter is a class used to fill a DataSet with DataTable objects; this class can also send modified DataTables back to the database for processing. Table 22-8 documents the core members of the DbDataAdapter base class, the common parent to every data adapter object (e.g., SqlDataAdapter and OdbcDataAdapter).
