DataServer Components
The DataServer is a set of software components that allows Progress and WebSpeed applications to access data in a supported ODBC data source. The DataServer enables access by translating standard Progress and WebSpeed code into calls appropriate to the ODBC data source. The application can thus manipulate the data from all supported ODBC data sources as though it were Progress-based data.
The DataServer consists of the components described in Table 1–1.
Figure 1–1 illustrates how the DataServer components are organized for both the Enterprise and the Personal DataServer for ODBC.

As shown in Figure 1–1, the components for the Personal DataServer for ODBC are organized similar to the Enterprise edition except that the DataServer is embedded in the client rather than executing separately.
In either case, a Progress or WebSpeed application uses the DataServer to work with the ODBC Driver Manager, which accesses the desired ODBC driver. The driver then accesses the relevant ODBC data source manager, which in turn accesses the data in the associated ODBC data source. Note that there is a separate ODBC driver for each supported data source.
Some of the DataServer components are linked with elements of the standard Progress architecture, as described in the “DataServer Configurations” section.
