Importing from Greenplum using Zoho Databridge

If you have data in a local /hosted Greenplum database, then you can easily import your data into Zoho Analytics using the Zoho Databridge. The Zoho Databridge bridges your local Greenplum database and Zoho Analytics server to fetch data from your local /hosted  Greenplum database. With this, you can also automate the import process to synchronize the data from your local /hosted Greenplum database into Zoho Analytics at a periodic interval.

13. I am unable to establish the connection between the local Greenplum database and Zoho Analytics server. How do I solve this?

This may happen due to various factors such as connectivity issues or privileges to access the protected data source. Refer to our Zoho Databridge Troubleshooting tip section to solve the specific issue you are facing.

Live Connect

1.How do I connect live with the Greenplum Database?

2. How long does it take for me to visualize my data in Zoho Analytics?

As there is no data import process involved, the loading time depends upon the amount of data stored in your Greenplum database and also the response time of your Greenplum database.

3. How can I edit the live connect setup?

4. How is Live Connect different from Data Import?

5. Will the reports/dashboards query hit my database server every time I open it or can it be cached in Zoho Analytics?
(or) Can I store a cache of my data points in Zoho Analytics to get quick access to my views?

Zoho Analytics allows you to create a cache for the reports in your live connect database to reduce the query fetching time.

To enable cache for your live connect workspace, please follow the below steps:

1. From your Workspace Explorer, click the Settings tab from the side menubar.
2. In the General - Workspace Settings page that opens, choose Yes for Enable Cache for this Workspace.
3. In Cache Refresh Interval in Minutes, specify the duration to refresh the report .
4. Click Save & Close.
   
   

A cache for the reports will be created.

Note: 

• Enabling cache will help create a cache for your reports in the workspace. This data will get updated periodically based on the time provided in the Cache Refresh Interval in Minutes. 
• You can create a cache only for the reports, and not for tables in the workspace.
• This option is available only for Live Connect.

6. Can I connect Views created in the Greenplum database (apart from Tables) to Zoho Analytics?

Yes, you can connect with both Views and Tables created in the Greenplum database to Zoho Analytics.

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

Yes. In case you have linked two or more tables in your Greenplum database using foreign keys, they will be linked automatically using a Look-up column in Zoho Analytics as well. 

8. I got an alert message "This view cannot be accessed due to some changes made in the table" while accessing my tables/reports in Zoho Analytics. What should I do? 

This alert message will be displayed when Zoho Analytics is not able to access the information from the Greenplum database. This could be because the tables/columns that you are trying to access in Zoho Analytics are deleted or renamed in the Greenplum database.

In this case, it is recommended that you remap the table/column. Refer to this presentation to know how to remap a table.

9. What is a Mismatch?

When you have created reports in Zoho Analytics over the tables or columns which no longer have a direct mapping in the Greenplum database, it will be listed as a mismatch. 

So, ensure that the tables/columns in Zoho Analytics workspace and Greenplum database match. The tables/columns that do not match will be listed in the Mismatch tab of the Local Database ConnectionSettings page.
 

10. When do Mismatches occur and how to resolve them?

11. Can I connect new columns added in my Greenplum database to Zoho Analytics?

Yes, you can connect the new columns that are added in your Greenplum database to Zoho Analytics from the Local Database Connection Settings page.

Note: If there exists a mismatch between the already available data in your Zoho Analytics workspace and your Greenplum database, Zoho Analytics will NOT be able to fetch the new column information. In this case, you need to first resolve the mismatches to connect to the new columns.

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

No, you cannot change the data type of the columns in Zoho Analytics.

13. Can I import data from other data sources into the same workspace that I have used to connect with the Greenplum database database?

No, you cannot import data from other data sources into the same workspace that you have used to connect with the Greenplum database.

14. Can I create Query Tables over the Greenplum data?

No, you will not be able to create Query Tables if you have setup the workspace using the Live Connect option. This is because this option does not fetch and store the data locally in Zoho Analytics. If you wish to create Query Tables, you can create the required query as a view in the data source and connect the same with Zoho Analytics.

15. What happens when I delete or rename the database in the Greenplum database?

When you delete or rename a database in the Greenplum database, Zoho Analytics loses its connectivity with the Greenplum database. After that, a warning message, as shown below, would be displayed. This error message will also be displayed if there are any connectivity issues or if your Greenplum database credentials have expired.

16. How do I remove the Setup?

You have to delete the workspace in Zoho Analytics to remove the connection setup. 

To delete the workspace,

1. Log in to Zoho Analytics
2. Click the More Actions icon that appears on mouse hover adjacent to the workspace name that you want to delete.
3. Click the Delete Workspace option.

17. What are the limitations of using the Greenplum database Live Connect?

Given below are a few shortcomings that one might face while using the Greenplum database Live Connect option.

• Data from your Greenplum database will NOT be locally stored in Zoho Analytics. Zoho Analytics will generate appropriate queries to fetch the required data live from the Greenplum database and show you the report. Hence, the loading time will directly depend on the performance of the Greenplum database server.
• Any changes such as column addition/deletion/renaming will not be mapped automatically. The user must manually map the updates made.
• Users cannot combine data from other data sources into the same workspace in which they have connected the Greenplum database.
• Users cannot create query tables.
• Users cannot change the data type of the columns in Zoho Analytics.
