How does Esri define and differentiate "workgroup geodatabases" and "desktop geodatabases".
The table of client and geodatabase compatibility identifies "Enterprise, workgroup, or desktop geodatabase" as distinct geodatabase types.
In the same help section, enterprise geodatabases are described, but the terms "workgroup geodatabase" and "desktop geodatabase" are not defined.
Searching the help for the term "workgroup geodatabase" leads to this topic, which discusses creating desktop or workgroup geodatabases, but doesn't distinguish between them.
Further complicating this is the use of the term ArcSDE, which has not existed as a product since the 10.2.2 release.
So, what are the definitions of "desktop geodatabase" and "workgroup geodatabase"? Would it be possible for Esri to provide a cleaned up, concise definition of the various geodatabase types, using consistent terminology?
