Connect Neo4j Graph Database with Helical Insight

We Can Use Neo4j Graph Database with EFW reports:

Note: This blog is applicable for HI Version Helical Insight v1.0.0

Follow these steps to use Neo4j Graph database with helical insight:

Step 1: First we have to Download Neo4j JDBC driver to Neo4j graph database with HI

You can download Neo4j driver from here

Step 2: Open “hi-repository” folder from the location where Helical Insight application is installed.

For Example: C:\Helical Insight\hi-repository\

Step 3: Now, open System folder and then open Drivers folder.

Step 4: On opening, a list of jar files for each database will be seen.

Step 5: Now, to add a new driver in the list, download database specific “JDBC driver jar file of type 4” file from the source  and then add the driver file into “Drivers” folder. 

Step 6: Now Create a EFW report, and open EFWD file to add the Neo4j connection details to access the Neo4j database.

Example:

<Connection id="1" type="sql.jdbc">
    <Driver>org.neo4j.jdbc.bolt.BoltDriver</Driver>
    <Url>jdbc:neo4j:bolt://localhost:7687?noSsl</Url>
    <User>neo4j</User>
    <Pass>neo4j</Pass>
</Connection>

Where

<Driver>org.neo4j.jdbc.bolt.BoltDriver</Driver> : Neo4j Bolt Driver

<Driver>org.neo4j.jdbc.bolt.BoltDriver</Driver> : Neo4j bolt JDBC URL

<User>neo4j</User> : username of the Neo4j DB

<Pass>root</Pass> : password of the Neo4j DB

Step 7: Now create a DataMap to write Neo4j database query.

Example:

<DataMaps>
    <DataMap id="1" connection="1" type="sql" >
        <Name>Neo4j Sample queery </Name>
       	<Query>
	<![CDATA[
          MATCH (cust:Customer)-[:PURCHASED]->(:Order)-[o:ORDERS]->(p:Product),(p)-[:PART_OF]->(c:Category 
          {categoryName:"Produce"})
          RETURN DISTINCT cust.contactName as label, SUM(o.quantity) AS value LIMIT 10
       ]]>
 </Query>
  </DataMap>
 </DataMaps>


Where

Name: A short description for the query

Query: The query to be executed, within a <![CDATA[ ]]> tag. Parameters can be specified like ${nameOfTheParameter}
