According to ESRI, "At 10.1, ArcGIS will support direct SQL access to all the leading DBMSs including SQL Server, DB2, Oracle, and Postgres. This will include direct access to native spatial data types in each of these systems. ArcGIS will support working with these spatial databases as easily as it works with geodatabases. For more complex spatial data and transactions, users will use the ArcGIS geodatabase environment ( i.e., topology, rasters, networks, replication, and archiving)."
Also, finally, "No. ArcIMS 10 was the last release. Its entire functionality has been replaced by ArcGIS Server. ArcIMS users have been provided upgrade paths to ArcGIS Server for a number of years. There are many reasons to migrate to ArcGIS Server including performance, capability, quality of mapping, functionality, and ease of administration."
