Creating the Data Source Name
This section describes how to edit the DSN configuration and then authenticate and connect to Neo4j APIs.
DSN Configuration
You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the installation process creates a both a user DSN and a system DSN, as described in Installing the Connector.
Note: The connector stores connection information in the Windows registry. To ensure that the connector can write to the registry, either run Power BI as an administrator or use a User DSN for your connection instead of a System DSN.
User DSN
Complete the following steps to edit the DSN configuration:
- Select Start > Search, and enter ODBC Data Sources in the Search box.
- Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
- Select the system data source and click Configure.
- Edit the information on the Connection tab and click OK.
System DSN
Configure the system DSN the same way as the user DSN, except you will need to switch to the System DSN tab before performing Step 3.
Connecting to Neo4j
CData Power BI Connector for Neo4j supports connections to self-managed Neo4j instances via the HTTP API. To connect, set the following connection properties:
- Server: The server hosting the Neo4j instance. An HTTP or HTTPS protocol prefix may be optionally prepended to the server name or address.
- Port: The port on which the Neo4j service is running. The provider connects to HTTP (7474) port by default. If connecting over HTTPS, supply the HTTPS port for the Neo4j instance specified in Server.
- User: The username of the user using the Neo4j instance.
- Password: The password of the user using the Neo4j instance.
- Database: The database to target in the Neo4j instance. Defaults to "Neo4j".
