Importing from Teradata using Zoho Databridge

If you have data in a local or hosted Teradata database, then you can import your data into Zoho Analytics using Zoho Databridge. Zoho Databridge bridges your local or hosted database and Zoho Analytics server, and allows importing data into a Zoho Analytics Workspace for analysis. You can also schedule automatic import of data into Zoho Analytics at periodic intervals.

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 the 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."  

Data Import

1. How do I import data from the Teradata using Zoho Databridge?

The below presentation explains how to import data from a Teradata using Zoho Databridge.

Note: It is mandatory to install Zoho Databridge to import data from the local Teradata database. Refer to the previous question to know how to Install. 

2. How long does it take for the data to be imported into Zoho Analytics?

Import will take a few minutes to hours depending on the volume of the data. Please note, if you access the Workspace before the initial fetch is completed, you may find the tables empty (with no data).

3. How can I edit the Import setup?

You can edit the import setup anytime by following the steps below:

  1. Open the Workspace.
  2. Click the Data Sources tab from the left bar.
  3. All the data sources for this Workspace will be listed. Click the Teradata data source that you want to edit. 
  4. The Data Sources page will open. Click Edit Connection.
  5. Modify the settings as needed and click Save. The connection details will be saved.

4. How can I schedule import from Teradata database?

Zoho Analytics allows you to automatically schedule the periodic import of data. You can schedule the import of data into an existing table by following the steps below. 

  1. Click the Data Sources tab from the left bar and click the Teradata data source for which you want to schedule import.
  2. The Data Sources page will open. Click Sync Settings.
  3. The Local Database - Synchronization Settings dialog will open.
  4. Select the required schedule interval from the Repeat drop-down menu. Supported intervals are:
    • Not Scheduled
    • Every 'N' Hours
    • Every Day
    • Weekly Once
    • Monthly Once
  5. Select when the data needs to be imported from Perform every option. 
  6. In the Notify me after every Sync Failure(s) drop-down menu, set the number of consecutive import failures after which you need to be notified.
  7. Click Save. Data will be imported into Zoho Analytics in the set interval. 

You can also schedule the import while initial import using the Schedule Setting option in the Step 4 of Import Wizard.

5. Will I be notified of import failures?

Yes, you will be notified after consecutive import failures, in case it occurs. To get notified on import failures, you need to set the number of consecutive import failures after which you need to be notified in the Notify me after every Sync Failure(s) option of the schedule import.

6. Import from Teradata database that is hosted in the cloud fails. How to solve this? 

Import from a cloud database may fail when the Databridge does not have the privilege to access the data. In case your database security system only allows access from restricted IP Addresses, then it will blocklist the server / machine where Databridge is installed. Ensure that you have the IP Address of the machine / server is in the allowlist, where the Databridge is installed. 

7. Can I import data from Teradata into an existing Zoho Analytics workspace?

Yes, you can import data from Teradata into an existing Zoho Analytics workspace.
Follow the below steps to import data into an existing workspace:

  1. Open the workspace into which you wish to import the data.
  2. Click Create > New Table / Import Data.
  3. The Import Your Data section will open. Click the Local Databases tab.
  4. The Import Wizard will open. Configuring the import will be similar to the steps followed in this presentation.​

8. Can I import data from Teradata into an existing table in Zoho Analytics?

Yes, you can import data into an existing table if you are importing from the same source database as the imported table. 

  1. From the required table, click Import Data > Import into this Table.
  2. The Select Data to Import tab of the Import wizard will open. 
  3. You can choose to import from a different table using the Single Table option or import using the Custom Query.

9. I have synced data from Teradata into a table. Can I change the data source of this table?

Yes, you can change the data source of a table, into which the Teradata has been synced. To do this,

  1. Click the Data Sources tab from the left bar and click the Teradata data source, for which you want to change the data source.
  2. The Data Sources page will open. Click the Edit Connection link.
    ​
  3. In the Local Database - Edit Connection dialog that opens, modify the data source. You can also change the databridge that fetches the data.
  4. Click Save to implement the changes made.

10. Can I import data from Teradata databases that are hosted in various networks/private clouds?

Yes, you can import from various databases that are hosted in different networks by installing multiple databridges. You need to install separate databridges for each network. To link all the databridge installations to your account, use the same installation key available in the Download dialog. 

Note:

  • Single databridge installation can import data from various data sources available in the same network.
  • You can install only one databridge per machine. 

11. Will foreign keys defined between my tables in the Teradata database be linked in Zoho Analytics as well?

Yes, the tables will be directly linked in Zoho Analytics, based on the foreign keys defined between your tables in the database. Click here to learn about look-up after importing data into Zoho Analytics.

12. Can I import tables from the same database into multiple workspaces in Zoho Analytics?

Yes, you can import tables from the same database source to multiple workspaces in Zoho Analytics. Read more about import.

13. Can I change the data type of the columns imported in Zoho Analytics?

Yes, you can change the data type of the columns imported into Zoho Analytics. However, it is necessary that the data type of your column is compatible with the data type of the column in your database for successful data synchronizations. It is always recommended that you change the data type in both your database as well as your Zoho Analytics Workspace.
