The ADO/WFC components leverage the rich functionality of Win32 platforms, and are designed for optimal performance with the Virtual Machine (VM) for Java technology. These components are part of the Microsoft® Data Access Components.
The following table summarizes the major ADO/WFC components:
| Component | Description |
| Connection | Provides basic connectivity to data sources and application servers. |
| Recordset | A data cursoring abstraction. Provides rich navigational semantics, as well as disconnected and batch mode operational modes. Intrinsically marshalable across process/machine boundaries (basic unit of “transport” for tabular data between business objects and client application contexts). |
| Command | A parameter-varying command execution component. |
| Field (Fields Collection) | Handles row metadata and values. Used to define the “shape” and dimension of Recordset objects. |
| AdoProperty (AdoProperties Collection) | A property container for component-specific properties. All ADO components have associated (and in some cases unique) property sets. |
| Parameter (Parameters Collection) | A value descriptor for objects utilized by Command components. |
| ObjectProxy | A surrogate for a remote business object. |
| DataSpace | A business object “factory” component. |
| DataBinder (and DataBinding) | A data binding and coordination agent for forms in an ADO-deployment context. (DataBinding is a helper class that associates a visual component’s bound fields to Recordset result fields.) |
| ConnectionEventHandler | A dispatch mechanism for Connection events to registered event listeners. |
| RecordsetEventHandler | A dispatch mechanism for Recordset events to registered event listeners. |
| CommandEventHandler | A dispatch mechanism for Command events to registered event listeners. |
| ConnectionEvent | An event descriptor specific for Connection events. |
| RecordsetEvent | An event descriptor specific for Recordset events. |
| CommandEvent | An event descriptor specific for Command events. |
| AdoException (Errors Collection) | A basic error exception class for reporting anomalous conditions in the ADO execution environment. |
