Data Access and Transactions

Client-Tier Elements

As described in the previous section, the client services tier provides the visual interface for presenting and gathering data. In a Web-based RDS application, the Web page represents the RDS front end. The RDS client tier contains the following components:

• A Web page or Visual Basic application containing an RDS.DataControl object and one or more data-aware controls.
• An RDS.DataSpace object and client-side proxy for middle-tier business objects. The default business object is RDSServer.DataFactory. You can develop custom business objects as well.
• A data cache and the client-side cursor engine, Cursor Service for OLE DB.

See the following:

• Data-Aware Controls
• Data Cache
• Client Cursor Engine
• Business Object Proxies and the RDS.DataSpace Object
