Feature Services
The authoring process involves setting up a map document to define the data and symbology that will be exposed by the service. If you plan on editing, you can also define the editing environment.
Defining the data
The layers and tables that you add to the map document will be exposed by the service. The following describes feature service data requirements:
All data must be from a single ArcSDE geodatabase.
All data must be registered with the geodatabase.
Write permissions for the ArcSDE data are required if you plan on editing the data. Note: When using OS authentication, these permissions must be granted to the ArcGISSOC user.
Versioned and unversioned data is supported; however, versioning is required if you plan on editing nonsimple types (for example, network edges) with the service.
