The following sections define terms related to ArcGIS Data Store. Since ArcGIS Data Store is part of an ArcGIS Enterprise deployment, additional terms are included here to clarify data stores in ArcGIS Enterprise and ArcGIS Server.
ArcGIS Data Store
ArcGIS Data Store is the software component that allows you to easily configure data stores for your portal's hosted feature layers and hosted scene layers, the hosted feature layers created as output from GeoAnalytics Tools, and the feature layers created to archive real-time data from a federated ArcGIS GeoEvent Server site.
Note that data store is a general term for any location where data is stored. ArcGIS Data Store allows you to configure a subset of data store types. The data stores you configure with ArcGIS Data Store are always used as part of an ArcGIS Enterprise deployment and are registered with your portal's hosting server.
ArcGIS Data Store account
The ArcGIS Data Store account is the login under which your ArcGIS Data Store service runs on Windows servers. You specify this account when you install ArcGIS Data Store. See ArcGIS Data Store account for more information.
ArcGIS Data Store directory
This is a directory you specify to store the files ArcGIS Data Store needs to run. This directory must be local to the ArcGIS Data Store installation.
This directory initially stores backup files for relational data stores, but once you've created a relational data store, you should configure it to create backup files in a shared network location instead.
ArcGIS Enterprise
ArcGIS Enterprise is the product line that allows you to create a Web GIS. It includes ArcGIS Server, Portal for ArcGIS, ArcGIS Data Store, and ArcGIS Web Adaptor.
See What is ArcGIS Enterprise? in the Portal for ArcGIS Administrator Guide for more information.
ArcGIS GeoAnalytics Server
ArcGIS Server sites are licensed to fill specific roles. An ArcGIS GeoAnalytics Server is a federated server that allows you to perform big data analytics using distributed computing.
In the context of ArcGIS Data Store, you need a spatiotemporal big data store for the data output from GeoAnalytics Tools used in the map viewer or Insights for ArcGIS. These tools are available in your portal if you have a federated ArcGIS GeoAnalytics Server.
See What is ArcGIS GeoAnalytics Server? for more information.
ArcGIS GeoEvent Server
ArcGIS Server sites are licensed to fill specific roles. An ArcGIS GeoEvent Server is a stand-alone or federated server site that allows you to stream real-time data.
In the context of ArcGIS Data Store, a federated ArcGIS GeoEvent Server can archive data from stream services into a feature layer that runs on the portal's hosting server. The archived data is stored in a spatiotemporal big data store. Note that the feature layer is not a hosted feature layer; when you delete the feature layer from the portal, the feature service is not deleted, and neither is the data stored in the spatiotemporal big data store.
See Managing spatiotemporal big data stores in the GeoEvent Server help for more information on archiving data.
ArcGIS GIS Server
(Also called GIS Server.)
ArcGIS Server sites are licensed to fill specific roles. An ArcGIS GIS Server allows you to serve such GIS resources as map services, feature services, geoprocessing services (tools), geocoding services (locators), geodata services, and scene services.
A portal's hosting server must be licensed as an ArcGIS GIS Server site to publish the types of services that hosted web layers require.
ArcGIS Image Server
ArcGIS Server sites are licensed to fill specific roles. An ArcGIS Image Server is a stand-alone or federated server site that allows you to serve cached or dynamic image services.
In the context of ArcGIS Data Store, the ArcGIS Enterprise deployment with which you are using ArcGIS Data Store must have a federated ArcGIS Image Server if you want to publish hosted image layers to the portal.
data store
In the context of ArcGIS, a data store is any location you keep the data used by ArcGIS.
In the specific context of ArcGIS Server, data stores are the file, database, geodatabase, or cloud storage locations you register with an ArcGIS Server site. Registering these locations with the ArcGIS Server site ensures the services you publish will have access to the data.
Some data stores registered with ArcGIS Server point to your data source; the data is maintained in that data store and is not copied anywhere else. When a service is published to the ArcGIS Server site, the data that populates the service comes from this registered source data.
Other data stores registered with ArcGIS Server have data copied into them at the time that the related service is published.
Note that web layers in Portal for ArcGIS are services that run on an ArcGIS Server site. If the data is copied to the data store when the service is published, the resultant web layer in Portal for ArcGIS is a hosted web layer. For more information, see Relationships between web services and portal items in the Portal for ArcGIS help.
GIS Server
See ArcGIS GIS Server.
federated server
A federated server is an ArcGIS Server site you have integrated into your portal to share authentication and automatically create items in the portal for the services you publish to the federated server.
See About using your portal with ArcGIS Server in the Portal for ArcGIS Administrator Guide for more information.
hosted web layers
Hosted web layers are items in your portal that have corresponding services running on the portal's hosting server.*
*The one exception to this is hosted image layers; they run on a federated ArcGIS Image Server rather than your hosting server.
Wskazówka:
When you open the item's page in Portal for ArcGIS, you will see (Hosted) in the name of the item on the Overview tab.
The data that populates the services and, therefore, the hosted web layers is copied to your data store when you publish. Hosted web layers require you to create a specific type of data store to hold this data. See Apps and functionality that require ArcGIS Data Store to determine which type of data store you need for each type of hosted web layer.*
*Hosted image layer data is copied to a registered file or cloud storage data store, not a data store created through ArcGIS Data Store.
When you delete a hosted web layer from your portal, the service is deleted from the GIS Server site, and the data is deleted from the data store.
For more information on hosted web layers, see Relationships between web services and portal items and Hosted web layers in the Portal for ArcGIS user help.
hosting server
A hosting server is the GIS Server you federate with your portal and set as the server to host web layers published to the portal.
See About using your portal with ArcGIS Server in the Portal for ArcGIS Administrator Guide for more information.
relational data store
A relational data store is a managed database for your portal's hosting server that stores the data for hosted feature layers.
spatiotemporal big data store
A spatiotemporal big data store is a distributed, scalable storage structure with full-text search capabilities that allows you to store and analyze feature layer data created to archive stream service data or store output from GeoAnalytics Tools.
tile cache data store
A tile cache data store is a set of databases that store caches for hosted scene layers. One database is created for each hosted scene layer in your portal.
