ESRI that spatially enables aRelational Database Management System . The spatial data may then be used as part of ageodatabase although this is not strictly necessary.The latest version, ArcSDE 9.3, is sold as a component of
ArcGIS Server . It is part of theArcGIS family of software products, that integrates geographic information query, mapping, spatial analysis, and editing within a multi-user enterpriseDBMS environment. ArcSDE enables organisations to move from a traditional approach — managing a separate collection of geographic data files — to an integrated environment in which spatial data is managed as a continuous database that is accessible to the entire organisation and easily published on the Web.ArcSDE is an application server that facilitates storing and managing spatial data (raster, vector, and survey) in a DBMS and makes the data available to many applications. ArcSDE allows you to manage spatial data in one of four commercial databases (IBM
DB2 ,Informix ,Microsoft SQL Server and Oracle). With the 9.3 release, support was added for the open sourcePostgreSQL database.ArcSDE serves data to the ArcGIS Desktop products (ArcView ,ArcEditor andArcInfo ), the ArcGIS development products (ArcGIS Engine and ArcGIS Server),ArcView 3.x andArcIMS . It is a key component in managing a multi-userGIS .ArcSDE grew to meet the need of users of geographic data for robust multi-user editing, storage and access of extremely large geospatial databases. ArcSDE supports the ESRI
geodatabase implementation.While the traditional
RDBMS software is used to keep track of the tables and records contained in the database, ArcSDE pushes the relational model higher so that geographic data - which comprises several tables - can be managed by client software seamlessly. The user is not aware of, nor do they have to deal with, the particulars of the RDBMS. Connections to the database are all routed through the ArcSDE middleware, which performs the storing, and retrieval of data.External links
