This is a recurrent question in my geodatabase seminars.
“ArcSDE” is a concept that has always created some confusion, and part of the reason is, I think, due to how ArcSDE has evolved overtime.
I have seen that some users tend to associate the concept ArcSDE with the “application service connections” which has been deprecated in 10.3. Sometimes, I see people mixing things up and ending up asking questions like, “Has Esri got rid of ArcSDE?”
It’s also common to see users asking in forums why they should use ArcSDE if there are many databases that support spatial data, multi-user editing, replication, and even spatial functions, as one of colleagues here in the Melbourne office found the other day. The confusion comes from the terminology used:
- Do I get the same spatial capabilities using native database spatial data versus ArcSDE enhanced spatial databases – even when both use the same spatial data types – for example, do I get the same capabilities using a MS SQLServer database using the Geometry spatial data type and a MS SQLServer ArcSDE enhanced database using Geometry spatial data type?
- Is it the same multiuser editing found in SQL Server or any other database and the multiuser editing available with ArcGIS?
- Is it the same “replication” functionality the one found in a database and the one we have with the Esri technology?
A short answer to all these questions is: – No, it is not the same.
