Rapidly Develop Neo4J-Driven Apps with Active Query Builder

Leverage the Active Query Builder SQL interface and .NET data access to create data-driven WinForms and ASP.NET apps backed by Neo4J.

Write standard .NET to expose Neo4J data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Neo4J enables standards-based access to Neo4J. This integration uses the Microsoft ADO.NET Provider for ODBC as a bridge between the ODBC Driver and the Active Query Builder objects to build a visual SQL composer.

Connect to Neo4J as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

To connect to Neo4j, set the following connection properties:

  • Server: The server hosting the Neo4j instance.
  • Port: The port on which the Neo4j service is running. The provider connects to port 7474 by default.
  • User: The username of the user using the Neo4j instance.
  • Password: The password of the user using the Neo4j instance.

Use SQL to Interact with Neo4J

Follow the steps below to create a WinForms visual query builder.

  1. Open Active Query Builder for .NET WinForms. ๐Ÿ‘ Opening Active Query Builder.
  2. In the new Windows Forms project go to the "File" menu and click "Connect..."
  3. Under Database Connections, click "Add..." ๐Ÿ‘ Adding a new Connection.
  4. Set your desired Connection Name (e.g. CData Neo4J), set Connection Type to "ODBC" and locate your previously configured DSN in the "User/System" DSN dropdown. ๐Ÿ‘ Selecting a previously configured DSN (Amazon Athena is shown).
  5. Click "OK" to save the new connection.
  6. Back in the Database Connection wizard, select the newly created connection and click "OK." ๐Ÿ‘ A newly added Connection (Amazon Athena is shown).
  7. Click "File" > "New Query" to create a QueryBuilder

You can now build queries visually: Double-click a table in the Columns Pane Area and an entity/relationship diagram is displayed in the Query Building Area. Columns that you select in the diagram are added to the query.
