Create Data Visualizations Based On MariaDB Data in Mode

Mode is a collaborative data platform that combines SQL, R, Python, and visual analytics in one place. When paired with CData Connect AI, you get instant, cloud-to-cloud access to MariaDB data for use in data visualizations. This article shows how to connect to MariaDB in Connect AI, connect to MariaDB data in Mode, and create a simple visualization using that data.

CData Connect AI provides a pure cloud-to-cloud interface for MariaDB, allowing you to build data visualizations from live MariaDB data in Mode — without replicating the data to a natively supported database. In order to create visualizations, users write SQL queries to gather data. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to MariaDB, leveraging server-side processing to quickly return the requested MariaDB data.

Configure MariaDB Connectivity for Mode

Connectivity to MariaDB from Mode is made possible through CData Connect AI. To work with MariaDB data from Mode, we start by creating and configuring a MariaDB connection.

1. Log into Connect AI, click Sources, and then click Add Connection
👁 Adding a Connection

2. Select "MariaDB" from the Add Connection panel
👁 Selecting a data source

3. Enter the necessary authentication properties to connect to MariaDB.

   The Server and Port properties must be set to a MariaDB server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, the tables from all databases are reported.

4. Click Save & Test
5. Navigate to the Permissions tab in the Add MariaDB Connection page and update the User-based permissions. 👁 Updating permissions
   

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create. 👁 Creating a new PAT
   
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to MariaDB data from Mode.
