A schematic dataset acts as the entry point for your schematic application. It is the core object that holds any schematic component. It can reside in a personal, file, or ArcSDE geodatabase.
A schematic dataset contains a collection of schematic diagram templates and schematic feature classes that share the same application domain—for example, water or electrical. A schematic dataset also contains schematic diagrams that have been generated according to the rules and symbology set for their related schematic diagram template. These schematic diagrams can be organized and stored in schematic folders.
ArcCatalog is the application used to create, rename, export, or remove a schematic dataset.
To create and configure the schematic diagram templates and schematic feature classes related to a schematic dataset, you need to edit the schematic dataset within Schematic Dataset Editor.
