Dameng

ArcGIS supports querying data from Dameng. You can publish map image layers and web feature layers that reference data in Dameng. If you publish an editable web feature layer from data in Dameng, editors can use the web feature layer to update the data.

Spatial data is stored in the Dameng geometry type. A typical installation of Dameng includes a spatial type; however, you must initialize it to use it.

See which versions of Dameng are supported with ArcGIS.

IBM Db2

ArcGIS supports querying data from Db2 databases. You can publish map image layers and web feature layers that reference data in Db2. When you publish editable web feature layers, editors can update the data by editing the web feature layer.

You have the option to create a geodatabase in a Db2 database. When you create data in a geodatabase in Db2 or register existing data with the geodatabase, that data can participate in enterprise geodatabase functionality and can support publishing additional types of web layers. See Enterprise geodatabases and ArcGIS Enterprise for more information about how geodatabase functionality affects web layers.

Db2 authenticates connections to the database using operating system logins. However, when you connect to Db2 from the Database Connections dialog box or the Create Database Connection geoprocessing tool, you can specify the Database authentication option. This allows you to save the specific username and password of the login, which is required if you will register the database connection with ArcGIS Server.

See which versions of Db2 are supported with ArcGIS.

Microsoft SQL Server

ArcGIS supports querying data from SQL Server databases. You can publish map image layers and web feature layers that reference data in SQL Server. When you publish editable web feature layers, editors can update the data by editing the web feature layer.

You have the option to create a geodatabase in a SQL Server database. When you create data in a geodatabase in SQL Server or register existing data with the geodatabase, that data can participate in enterprise geodatabase functionality and can support publishing additional types of web layers. See Enterprise geodatabases and ArcGIS Enterprise for more information about how geodatabase functionality affects web layers.

Although Microsoft allows SQL Server user accounts to write data to schemas of any name, ArcGIS requires that user accounts that create tables, views, or other objects in the database have identical usernames and schema names. For example, you cannot connect from ArcGIS as elmer and write to a schema named dataowner.

See which versions of SQL Server are supported with ArcGIS.

Oracle

ArcGIS supports querying data from Oracle databases. You can publish map image layers and web feature layers that reference data in Oracle. When you publish editable web feature layers, editors can update the data by editing the web feature layer.

ArcGIS supports Oracle SDO_Geometry and Esri ST_Geometry spatial types in Oracle databases. SDO_Geometry is a separate, third-party installation. To use the Esri ST_Geometry type to store spatial data, copy the ST_Geometry shape library to your Oracle machine and run the Create Spatial Type geoprocessing tool to create the ST_Geometry type, subtypes, and functions.

You have the option to create a geodatabase in an Oracle database. These automatically install and use the ST_Geometry type. When you create data in a geodatabase in Oracle or register existing data with the geodatabase, that data can participate in enterprise geodatabase functionality and can support publishing additional types of web layers. See Enterprise geodatabases and ArcGIS Enterprise for more information about how geodatabase functionality affects web layers.

See which versions of Oracle are supported with ArcGIS.

PostgreSQL

ArcGIS supports querying data from PostgreSQL databases. You can publish map image layers and web feature layers that reference data in PostgreSQL. When you publish editable web feature layers, editors can update the data by editing the web feature layer.

ArcGIS supports PostGIS geometry and geography types and the Esri ST_Geometry spatial type in PostgreSQL databases. PostGIS is a separate, third-party installation. To use the Esri ST_Geometry type to store spatial data in a database, copy the st_geometry library into your PostgreSQL installation and run the Create Spatial Type geoprocessing tool to create the ST_Geometry type, subtypes, views, and functions.

You have the option to create a geodatabase in a PostgreSQL database. When you create data in a geodatabase in PostgreSQL or register existing data with the geodatabase, that data can participate in enterprise geodatabase functionality and can support publishing additional types of web layers. See Enterprise geodatabases and ArcGIS Enterprise for more information about how geodatabase functionality affects web layers. See one of the following for instructions to create a geodatabase in PostgreSQL:

• Create a geodatabase in PostgreSQL on Linux
• Create a geodatabase in PostgreSQL on Windows

Although PostgreSQL allows user accounts to write data to schemas of any name, ArcGIS requires that user accounts that create tables, views, or other objects in the database have identical usernames and schema names. For example, you cannot connect from ArcGIS with the username vlad and write to the public schema.

SAP HANA

ArcGIS supports querying data from SAP HANA databases. You can publish map image layers and web feature layers that reference data in SAP HANA. When you publish editable web feature layers, editors can update the data by editing the web feature layer.

You have the option to create a geodatabase in an SAP HANA database. When you create data in a geodatabase in SAP HANA or register existing data with the geodatabase, that data can participate in enterprise geodatabase functionality and can support publishing additional types of web layers. See Enterprise geodatabases and ArcGIS Enterprise for more information about how geodatabase functionality affects web layers.

Keep the following information in mind when using SAP HANA:

• SAP HANA uses columnar data storage, which behaves as its own index. Therefore, the spatial columns in SAP HANA tables do not require a spatial index for query performance.
• SAP HANA does not use user-defined indexes; therefore, you do not manage or rebuild indexes on tables in SAP HANA.
• When you load data into SAP HANA, the spatial reference used by the data must exist in the SAP HANA system table.
• SAP HANA redefined its spatial reference system EPSG ID 4326 from a planar representation of WGS84 to a round-earth representation. Tables that store spatial data in SAP HANA with spatial reference system 4326 may not behave as expected in ArcGIS.

  The round-earth implementation of WGS84 (EPSG ID: 4326) in SAP HANA contains key limitations that make it unsuitable when working with certain types of data. For example, global datasets that exceed hemisphere boundaries or cross-hemisphere boundary lines return inconsistent results. Data you create or load using ArcGIS continues to be stored using a planar version of the WGS84 (EPSG ID 1000004326) coordinate system to ensure that ArcGIS can work with all types of data. However, ArcGIS can read round-earth WGS data that you create in SAP HANA using SQL or a third-party product.

• SAP HANA stores spatial reference system information in its ST_SPATIAL_REFERENCE_SYSTEMS system view. Spatial data you load into SAP HANA must either have a null spatial reference or use a spatial reference that exists in the ST_SPATIAL_REFERENCE_SYSTEMS system view. If this view does not contain the spatial reference system for data you want to load, use the SAP HANA CREATE SPATIAL REFERENCE SYSTEM Statement to update the view with the spatial reference system you need.

  Tip:

  More information can be found in the CREATE SPATIAL REFERENCE SYSTEM page of the SAP HANA Spatial Reference documentation.

  If the spatial data you import or copy to your SAP HANA database does not have a spatial reference defined, SAP HANA assigns a default SRID of 0, a Cartesian spatial reference system that works with data on a flat 2D plane.

See which versions of SAP HANA are supported with ArcGIS.

Teradata Vantage

ArcGIS supports querying data from Teradata. You can publish map image layers and web feature layers that reference data in Teradata. If you publish an editable web feature layer from data in Teradata, editors can use the web feature layer to update the data.

To connect from ArcGIS to a Teradata Vantage, you must install the Teradata GSS client, ICU library, and ODBC driver on the ArcGIS client machines in a specific order. See Connect to Teradata for information.

The following is a list of guidelines for using a Teradata Vantage with ArcGIS:

• The spatial columns in your tables must be named shape or aliased to shape in a view.

  The underlying storage for the TeradataST_Geometry type is CLOB; therefore, the name or alias of the column (shape) is the only way ArcGIS can identify that the column stores spatial data.

• When you add tables to Teradata from an ArcGIS client, ArcGIS always creates the tables in the user's own database. ArcGIS does not support creating tables in a database other than the user's own database. (The user and database must have the same name.) Tables added outside of ArcGIS do not have to follow this rule, and users connected to Teradata from ArcGIS can still view and publish the data. If you publish an editable feature service, users can edit the data.
• You must use the tessellation functions provided by Teradata to create and maintain a spatial index on a Teradata ST_Geometry column.

  Teradata uses the tessellation spatial index with a predefined area of interest. Therefore, ArcGIS spatial operations that are based on dynamic inputs, such as zoom in, zoom out, and pan, cannot use the tessellation index. However, the tessellation index can be used in a query layer if the SQL statement used to define the query layer explicitly uses the tessellation index to query a subset of data based on an area of interest.

• ArcGIS requires a unique identification field to render features in a map and to publish web services. ArcGIS Pro prompts you to specify this unique ID field when you add a spatial table to the map.

  ArcGIS tools do not insert new values into the unique ID fields in a database; rather, they rely on the database to insert values to the field. Since Teradata does not have a data type or built-in mechanism to populate values in an ID field, ArcGIS tools that create rows in a database table cannot be used with Teradata.

• As a Teradata user, you know that Teradata 14.x ST_Geometry only supports two-dimensional spatial data; therefore, you cannot paste spatial data that contains z- or m-coordinates into Teradata 14.x. Teradata 15.0 ST_Geometry supports z-coordinates but not m-coordinates; therefore, you cannot paste spatial data that contains m-coordinates into Teradata 15.0.
• In most cases, you store large amounts of data in a Teradata Vantage. To visualize, perform analyses, or publish data from an ArcGIS client, use a subset of data. How you do this depends on what you want to do with the data.
  • If you are adding data to ArcGIS Pro for viewing and analysis within the map, add a query layer and define the query layer expression to return only a subset of the data.
  • If you are adding data to ArcGIS Pro to publish a map image layer that references registered data, define a database view that contains only a subset of the data. Database views are stored in the database. You can use the Create Database View geoprocessing tool or an SQL client to define views.
  • If you are adding data to ArcGIS Pro to publish a feature layer that references registered data or to publish to a portal, uncheck the option to Make newly added layers visible by default before adding your data to the map. Next, create a definition query for the layer that defines a subset of data using SQL. Once you have restricted the amount of data that displays on the map, make the layer visible and prepare your map for publishing.

  Caution:

  Unless your map is set so that data is not automatically displayed when added, do not drag data directly from your database connection to the map if you have not already defined a subset of data. Extremely large datasets, as are normally stored in a data warehouse appliance, would take an inordinate amount of time to display on the map.

• If you use ArcGIS to add a feature class to your Teradata database and the spatial reference you specify for the feature class is not in the Teradata system table, ArcGIS adds a record to the Teradata SPATIAL_REF_SYS table and, consequently, the GEOMETRY_COLUMNS table.

  This allows you to use more spatial references than are provided by default with Teradata. However, upgrades to major Teradata releases may drop these tables and re-create them with only default values in them.

  Before you upgrade Teradata, you should always make a backup of your database. Be sure that this includes the records in these tables so you can restore them, if necessary, after a Teradata upgrade. You can follow this general procedure to back up and restore the SPATIAL_REF_SYS and GEOMETRY_COLUMNS records during a database upgrade operation:

  1. Create a backup of your database.
  2. Connect to a database in which you will make copies of the SPATIAL_REF_SYS and GEOMETRY_COLUMNS tables.

     In this example, the database is named mybackupdb.

     database mybackupdb;

  3. Create backup copies of your tables.

     In this example, source tables are in the sysspatial database.

     CREATE TABLE mybackupdb.spatial_ref_sys 
       AS sysspatial.spatial_ref_sys WITH DATA;
     
     CREATE TABLE mybackupdb.geometry_columns 
       AS sysspatial.geometry_columns WITH DATA;

  4. Upgrade the Teradata source database.
  5. Connect to the database to which you copied the tables.
  6. Restore the tables to your upgraded database.

     --Restore the geometry columns table.
     INSERT INTO sysspatial.geometry_columns 
       SELECT * FROM mybackupdb.geometry_columns;
     
     --Restore the spatial_ref_sys table.
     INSERT INTO sysspatial.spatial_ref_sys 
       SELECT * FROM mybackupdb.spatial_ref_sys 
       MINUS 
         SELECT * FROM sysspatial.spatial_ref_sys;

  7. Once the contents of the tables are restored, you can delete the backup copies of the tables.

     DROP TABLE mybackupdb.spatial_ref_sys;
     
     DROP TABLE mybackupdb.geometry_columns;

  8. If necessary, regrant privileges on these tables to users who create data in the database.

Cloud-based databases as a service

ArcGIS supports several cloud-based database-as-a-services offerings. For a list of the services currently supported, see the requirements for using ArcGIS with databases in the cloud.

Always co-locate your ArcGIS clients on the same cloud and in the same location (region) as your cloud databases.

ArcGIS clients that connect to most cloud-based database services require a database client.

Cloud data warehouses

ArcGIS supports several cloud data warehouses for query and analysis.

For optimal performance, co-locate your ArcGIS clients on the same cloud and in the same location (region) as your cloud data warehouse when connecting to the data in the data warehouse. Co-locate clients that access web services that use a snapshot of the data with the ArcGIS Server site where the service is running.

ArcGIS clients that connect to cloud data warehouses require you install client libraries provided by the cloud data warehouse vendor.
