• Data Import: Data in the Amazon RDS - MySQL database will be imported and stored in Zoho Analytics. You can setup periodic schedules to fetch the latest data automatically from your Amazon Redshift database. Report loading time will be faster as the data is stored in Zoho Analytics.
• Live connect: In this mode, data will not be imported from Amazon RDS - MySQL database and stored in Zoho Analytics. Instead for the reports that you create Zoho Analytics will generate appropriate queries that will fetch the required data live from the database and show you the report. In this case the loading time will directly depend on the performance of Amazon RDS - MySQL database.

Data Import

1. How do I import data from the Amazon RDS - MySQL database?

2. How can I edit the setup?

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

After setup, you might have to wait sometime for the initial fetch to happen. This depends upon the amount of data fetched from Amazon RDS - MySQL database and also the response time of the Amazon RDS server. You will receive an email notification once the import is complete. If you access the workspace before the initial fetch, it will not display any data.

4. Can I import data from my Amazon RDS - MySQL database into an existing Zoho Analytics workspace?

Yes. Follow the below steps to import data into an existing workspace:

• Open the Workspace into which you wish to import the data.
• Click the Import Data button in the side panel.
• Click Cloud Databases option. 

Configuring the import will be similar to the steps followed in this setup presentation.

5. Will foreign keys defined between my tables in Amazon RDS - MySQL database be linked in Zoho Analytics as well?

No, the tables will not be directly linked in Zoho Analytics. However, you can link two or more tables in Zoho Analytics using the Look-up feature. Click here to learn about look-up.

We have plans to fetch the foreign key details from Amazon RDS and automatically link those tables in Zoho Analytics using lookup columns in the future.

6. 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 MySQL database for successful data synchronizations. It is always recommended that you change the data type in both your Amazon RDS - MySQL database as well as your Zoho Analytics database.

7. How do I remove the setup?

To remove the setup,

• Login to your Zoho Analytics account.
• Open the corresponding Workspace.
• In the Explorer tab, click Data Sources button.
• In the Data Sources tab that opens click the Settings icon and select Remove Data Source as shown in the snapshot.

Please do note that this only removes the connection. You can still continue accessing the workspace in Zoho Analytics.

Live Connect

1. How do I connect live with the Amazon RDS - MySQL database?

2. How can I edit the setup?

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

After setup, you might have to wait sometime for Zoho Analytics to fetch the required details from the source database. This depends upon the amount of data stored in your Amazon RDS - MySQL database and also the response time of your database server. 

4. Will foreign keys defined between my tables in Amazon RDS - MySQL database be linked in Zoho Analytics as well?

In case you have linked two or more tables in your Amazon RDS - MySQL database using foreign keys, they will be linked automatically using a lookup column in Zoho Analytics as well. Refer to this help link to know more.

5. What is a Mismatch?

When you connect live with your source database, it is necessary that the data in the source (database) tables and the corresponding tables in Zoho Analytics match. When there is a mismatch, they will be listed in the Mismatch tab in the Local Database Connection settings page. 

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

8. What happens when I add new columns in my source database?

To add the new columns that are added in your Amazon RDS - MySQL database into Zoho Analytics, you must trigger the Sync Design option from the Amazon RDS Connection page. To know how to do that refer to this presentation.

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

No, you will not be allowed to change the data type of the column in Zoho Analytics.

10. Can I import data from other data sources into the same workspace?

No, you cannot import data from other databases into this workspace.

11. Can I create Query Tables over the Amazon RDS - MySQL data?

No, you will not be able to create query tables if you have setup the database using the Live connect option. This is because this option does not fetch the data and store it locally in Zoho Analytics. If you wish to create query tables, we request you to use the Data Import option.

12. What happens when I delete or rename the database in Amazon RDS - MySQL database?

When you delete or rename a database in Amazon RDS - MySQL, Zoho Analytics loses its connectivity with the source database. If you have renamed the database, click on the Edit Connection button and update the settings (Refer this presentation). If you have deleted the database in Amazon RDS - MySQL database, then the corresponsing workspace in Zoho Analytics needs to be deleted as well (Refer next question). 

13. How do I remove the setup?

If you have used the Live connect option to fetch the data, then you will have to delete the workspace in Zoho Analytics to remove the connection. 

14. What are the limitations of using the Live Connect?

• As data from the source database is not stored locally in Zoho Analytics, it might take some additional time to load reports. This loading time will depend on the performance of the source database.
• Any change in column details will not be synchronized automatically. The setup needs to be manually synced to access reports with the latest data. 
• Query tables cannot be created in a workspace setup with live connect.
• Data from other data sources cannot be imported into this workspace.
• The data type of a column in Zoho Analytics cannot be changed. The data type needs to be changed in the source database, and then resynced with the Zoho Analytics application.
