Amazon RDS supported database engine in Bold bi

• MySQL
• MariaDB
• Amazon Aurora MySQL
• SQL server
• PostgreSQL
• Amazon Aurora PostgreSQL
• Oracle

Database Engine

There are two connection types available in a data source:

* Live mode
* Extract mode

Live mode connection

In this connection type, a data source is directly fetched from the source. Choose the Live mode option for this connection.

Data Preview

1. Click Connect to connect to the Amazon RDS server with configured details.

The schema represents the collection list retrieved from the Amazon RDS server. This dialog displays a list of schemas in treeview and their corresponding values.

2. Now, the data design view page with the selected table schema opens. Drag and drop the table.

   

   You can use the Code View options for passing queries to display data.

   

3. Click Save to save the data source with a relevant name.

Extract mode connection

In this connection type, a data source is fetched from the source periodically. Choose the Extract mode option for this connection.

Refresh Settings

Steps to configure the data source refresh settings:

1. Click on Refresh Settings in the configuration panel.

   

2. Select the recurrence type, recurrence start and end dates in the Refresh Setting dialog box.

   • Data refresh can be scheduled hourly, daily, weekly, and monthly.
   • The Application Time Zone is displayed below the date picker. The start time of the schedule is converted to the client Time Zone and shown on the right side for users’ convenience. After selecting, click Schedule.

   

Preview and data import

1. Click Connect to connect to the Amazon RDS server with configured details.
2. The Extract Data dialog opens. This dialog has two modes of connection either via Table or Custom query. . Under custom query option, write the required query and click Connect.

Under Table option, the dialog displays list of tables and views in treeview. Select the required table(s) or view(s) from treeview to use in the designer. The option is available for configuring incremental refresh column (The table must have a primary key column and date column to configure this option) for the selected items in the right side panel. If you configured it, then the data source will work on Incremental update, otherwise works on Full load concept. And finally click Connect.

3. Now, the data design view page with the selected table schema opens. Drag and drop the table.

   

   You can use the Code View options for passing a query to display data.

   

4. Click Save to save the data source with a relevant name.

NOTE: In the future, you can edit the connection information for both Live and Extract mode connections using the Edit Connection option.

Connect using custom attribute and dashboard parameter

We have added support for custom attributes and dashboard parameters to the data source connection. You can connect to the data source using custom attributes or dashboard parameters.

Custom Attribute

Dashboard Parameter

Note: Refer to the Dashboard Parameter Documentation and Custom Attributes Documentation for more details.
