| ment framework for ArcGIS. At ArcGIS 9.3, the geodatabase offers improved spatial data management and enhanced capabilities for integration with enterprise systems.
ArcGIS 9.3 geodatabase enhancements include
Raster data management
-
- New geoprocessing tools make the transfer of unmanaged raster catalogs (in Microsoft Access personal geodatabases and file geodatabases) from one location to another much easier.
- Geodatabase replication
-
- Microsoft Access personal geodatabases and file geodatabases can participate in one-way replication as child geodatabases.
- ArcGIS 9.3 allows for more detailed logging of geodatabase replication activity.
- Direct Connect backward compatibility
-
- ArcGIS 9.3 clients can make direct connections to pre-9.3 enterprise geodatabases (e.g., 9.2, 9.1, and 9.0).
- Backward compatibility allows easier implementation of phased migration strategies for new ArcGIS releases.
- Versioned editing
-
- The Merge Geometries option enhances conflict and reconcile management.
- The Version Changes Viewer tool allows a version to be compared with an ancestor version without performing a reconcile operation.
- Support for PostgreSQL (Open Source DBMS)
-
- Enterprise geodatabases can be implemented on PostgreSQL with full support of the geodatabase data model.
- Vector geometry is stored in the ESRI spatial type.
- PostGIS Open Source spatial type is supported.
- Support for SQL Server 2008
- ArcGIS 9.3 will support the two new spatial types in Microsoft SQL Server 2008. A geodatabase implemented on SQL Server 2008 will be able to store vector geometry in either spatial type (Geography or Geometry).
- New 64-bit platform support
-
- Enterprise ArcSDE technology is now available as a native 64-bit application for Windows
