A dataset encapsulates all RiverWare knowledge about the database. In general, there are two types of knowledge contained in a dataset, configuration information and the database specification.

In RiverWare, datasets are defined and configured in the Dataset Manager as shown in Figure 4.17. The Dataset Manager is accessed from the Utilities, then Dataset menu on the DMI Manager. Selecting Edit, then New DSS Dataset, for example, adds a new DSS dataset.
