Types of datasets

A feature service supports datasets stored as feature layers, feature layer views, and tables. This section provides an overview of the data structures they support and the functionality they provide.

Feature layers

A feature layer is a spatially-enabled table in a feature service that contains features. All features in a feature layer have the same type of geometry (point, multipoint, polyline, polygon, or envelope), set of attributes, and spatial reference. A feature service can contain multiple feature layers.

Below is an example of a feature layer that contains parcel features. Each feature contains a polygon geometry and a set of attributes.

Feature layer views

A feature layer view, also known as a view, is a feature layer with a definition that only exposes a subset of the features, fields, and/or capabilities of an existing feature layer. A view supports all of the same functionality as a feature layer. If the underlying data changes in the original feature layer, the changes are reflected in all associated views. Feature layer views are typically used to expose a subset of the data that is available in an existing feature layer. They also support all of the sharing levels available regardless of the underlying feature layer's sharing level.

Below is an example of a feature layer view that only provides access to commercial parcels. Each feature contains a polygon geometry and set of attributes. This view is configured to only allow editing on commercial parcels. Only the owner or a group of ArcGIS users with the correct access and privileges can edit the features.


A table is a non-spatially enabled feature layer in a feature service. A table contains features with attributes but no geometry. Use hosted tables to securely access, query, and edit data as stand-alone tables. You can also join tables to other feature layers with a relation.

Below is an example of a table that contains features with attribute information for parcels.
