Schematic datasets in a geodatabase in Oracle

Schematic datasets are similar to feature datasets, but they contain a collection of schematic diagram templates and schematic feature classes. They are used to graphically visualize and manipulate network data.

Schematic datasets in ArcGIS Desktop

In the Catalog tree, schematic datasets have the following icon:

Schematic dataset icon

When you expand a schematic dataset, you can see the schematic diagrams it contains. These diagrams have the following icon:

Schematic diagram icon

The names of the schematic dataset and schematic diagram in a geodatabase in Oracle contain the name of the dataset owner and the names of the dataset and diagram themselves.
