Zoho Databridge

1.What is Zoho Databridge?

Zoho Databridge is a lightweight independent utility that bridges your on-premise data source and Zoho Analytics server, to enable easy data import. You can also automate the import process to synchronize the data from your local or hosted database into Zoho Analytics at periodic intervals.

2. How do I install Zoho Databridge?

Note: It is mandatory to install Zoho Databridge to import data from local Teradata database.

3. What are the prerequisites to successfully import data into Zoho Analytics?

This database requires a driver to connect to Zoho Analytics. Place the JDBC jar file for database inside the <Databridge>/lib/drivers folder to import data into Zoho Analytics. To do this,

1. Download the JDBC jar file.
2. Open the already downloaded Zoho Databridge folder and navigate to lib > drivers folder.
3. Copy the downloaded JDBC jar file and paste it in the drivers folder.
4. Restart Zoho Databridge.
   

Note: It is mandatory to fulfil the prerequisites. On failing, you will receive an alert message "Driver not found. Put the appropriate jar required to connect to your database in <Path to Databridge>/lib/jars folder."
