ArcSDE
is a server software product used to access massively large multiuser geographic databases stored in relational database management systems (RDBMSs). It is an integrated part of ArcGIS and a core element of any enterprise GIS solution. Its primary role is to act as the GIS gateway to spatial data stored in a RDBMS.

ArcSDE provides a suite of services that enhance data management performance, extend the range of data types that can be stored in a RDBMS, enable schema portability between RDBMSs, and offer configuration flexibility.

With ArcSDE you can

  • Serve spatial data to ArcGIS Desktop (ArcReader, ArcView, ArcEditor, and ArcInfo), to Internet clients through ArcIMS, and to applications developed with ArcGIS Engine and ArcGIS Server.
  • Serve ESRI's file-based data using ArcSDE for Coverages.
  • Manage geographic information in one of four commercial databases—IBM's DB2 Universal Database and Informix Dynamic Server, Oracle, and Microsoft SQL Server.

ArcSDE offers a number of important advantages for geodatabase users.

  • High performance
  • Extremely large data volumes
  • Spatial data integrity to ensure data fidelity
  • Integrated transaction model for multiuser GIS
  • Comprehensive geographic information management of all geodatabase types (vectors, rasters, survey, terrains, geoprocessing models, database schemas, metadata, and others)
  • Common database interface to all leading RDBMSs
  • Support for the geodatabase and ESRI's industry data models
  • Reduced cost of ownership


ArcSDE is an advanced geographic application server for relational databases. It allows you to manage geographic information in any of several RDBMSs and to serve your data openly to all ArcGIS applications.
