What is an ArcSDE service?

An ArcSDE service, also known as an ArcSDE application server or a three-tiered architecture, conveys spatial data between GIS applications and a geodatabase.

The database may be any of the supported database management systems (DBMSs)—Oracle, SQL Server, Informix, DB2, or PostgreSQL.

TipTip:

Beginning with ArcGIS 10.1, download the ArcSDE application server installation from the Esri Customer Care Portal.
