ArcSDE
ArcSDE is the GIS gateway to relational databases. It allows you
to manage geographic information in your chosen DBMS and serve
your data openly to the ArcGIS Desktop and other applications.
ArcSDE is a key component in a multiuser ArcGIS system. It
provides an open interface to relational database management systems
and allows ArcGIS to manage geographic information on a variety
of different database platforms including Oracle, Microsoft SQL Server,
IBM® DB2®, and Informix®.
ArcSDE acts as the gateway between the rest of ArcGIS and your
relational database. When you need a very large, multiuser database
that can be edited and used simultaneously by many users, ArcSDE
adds the necessary capabilities to your ArcGIS system by enabling you
to manage your shared, multiuser geodatabase in a DBMS. It does this
by adding a host of fundamental GIS capabilities.
ArcSDE allows you to:
• Manage and maintain your geodatabase in the DBMS that you select.
• Have multiple users edit and maintain the geodatabase. ArcSDE
provides long transaction and version support for your DBMS.
• Serve multiple ArcGIS users anywhere on your network.
Centralizing your DBMS server significantly enhances performance
for large multiuser systems.
• Open your ArcGIS geodatabase to other users who use MapObjects®,
ArcView GIS 3, and computer-aided design (CAD) applications.
• Build Open GIS Consortium (OGC)-compliant applications that work
with features in your geodatabase.
• Build SQL applications that work with the tables and rows in the geodatabase.
