Data Sets have no corresponding ADODB object, but both classes of Data Sets behave similarly to disconnected Recordsets in the following ways: Use the following table of contents to navigate to the most important differences between Data Sets and disconnected Recordsets, then get methods for generating ADO. Parameters are optional for ADODB commands, but not for updatable Table Adapters, which have four standard commands— Select Command, Insert Command, Update Command, and Delete Command. NET objects with VS 2005 and SQL Server 2000 or 2005.NET objects with VS 2005 and SQL Server 2000 or 2005. VS 2005 materializes Table Adapters, Data Sets, Binding Sources, and Binding Navigators as named objects in the form design tray.Trends come and go, but your DB strategy shouldn’t be a flavor of the month.Learn why you shouldn’t get distracted by new DB technology, how Facebook is using a RDBMS to do the data slicing and dicing they can’t in Hadoop, and more. NET and typed Data Sets are the preferred method for retrieving and updating relational tables, although Data Sets aren't limited to processing relational data.Expand the Tables node and mark the Customers table.Accept Northwind Data Set as the Data Set Name, as shown in Figure 1-7.objects, see Data Sets, Data Tables, and Data Views.

You can save the schema as an XML schema with the Write Xml Schema method, and both schema and data can be saved using the Write Xml method.NET uses the term data source as a synonym for a typed Data Set with a predefined, persistent database connection. NET data source is similar to using VB6's Data Environment Designer to specify an OLE DB data provider from one or more tables.Unlike the Data Environment Designer, multi-table Data Sets don't have the hierarchical structure that the OLE DB Shape provider creates for display in VB6's Hierarchical Flex Grid control.Figure 1-5 compares the objects required by updatable ADODB Recordsets and ADO. Table Adapters and Data Sets also appear in the Toolbox's Project Name Components section; the Data section has Data Set, Binding Source, and Binding Navigator controls.During the early part of VS 2005's long gestation period, these design-time objects collectively were called Data Components, Binding Source was called a Data Connector, and Binding Navigator was Data Navigator.
