What exactly is ArcSDE offloading to SQL Server2008?

Remember that the ArcGIS geodatabase is a very proprietary data model, allowing you to store not only geographic items (features) but also tables, topology rules, data access rules, locking schemes, business rules, etc. SQL Server 2008 is still at heart simply a data storage platform. This means that the bulk of the management of your GIS data will still be handled by ArcSDE.

ArcSDE will store geographic data in the new GEOGRAPHY and GEOMETRY data types. This allows SQL to manage it’s own spatial indexes on the data. Doing this also allows ArcSDE to take advantage of the built-in spatial functions for simple requests.

之前也一直再考虑这个问题今天看到这篇blog和大伙分享下；

看来Arcgis9.3还要在发布sp1或是sp2的时候才能支持再sql Server2008上存储和读取数据，另了解了下，arcgis9.3也将支持PostgreSQL DB。
