Spatial Databases in #InfoSWMM and #InfoSewer using ArcCatalog™

With ArcCatalog™ , you can explore and manage geographic data stored in an RDBMS through ArcSDE™ . Similarly, SDE for Coverages lets you access coverage, ArcInfo™ LIBRARIAN, and ArcStorm™ databases the same way you access data from an RDBMS. To access these spatial databases, you must add a spatial database connection to the Catalog.

Refer to the section on Database Connections folder -> Spatial Database Connection link in the ArcGIS help file to learn more.
