Use CData Connect AI and datapine to build visualizations and dashboards with access to live PostgreSQL data.

datapine is a browser-based business intelligence platform. When paired with the CData Connect AI, you get access to your PostgreSQL data directly from your datapine visualizations and dashboards. This article describes connecting to PostgreSQL in CData Connect AI and building a simple PostgreSQL-connected visualization in datapine.

CData Connect AI provides a pure SQL Server interface for PostgreSQL, allowing you to query data from PostgreSQL without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to PostgreSQL, leveraging server-side processing to return the requested PostgreSQL data quickly.

Configure PostgreSQL Connectivity for datapine

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

  1. Log into Connect AI, click Sources, and then click Add Connection
  2. πŸ‘ Adding a Connection
  3. Select "PostgreSQL" from the Add Connection panel
  4. πŸ‘ Selecting a data source
  5. Enter the necessary authentication properties to connect to PostgreSQL.

    To connect to PostgreSQL, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the data provider connects to the user's default database.

    SSH Connectivity for PostgreSQL

    You can use SSH (Secure Shell) to authenticate with PostgreSQL, whether the instance is hosted on-premises or in supported cloud environments. SSH authentication ensures that access is encrypted (as compared to direct network connections).

    SSH Connections to PostgreSQL in Password Auth Mode

    To connect to PostgreSQL via SSH in Password Auth mode, set the following connection properties:

    • User: PostgreSQL User name
    • Password: PostgreSQL Password
    • Database: PostgreSQL database name
    • Server: PostgreSQL Server name
    • Port: PostgreSQL port number like 3306
    • UserSSH: "true"
    • SSHAuthMode: "Password"
    • SSHPort: SSH Port number
    • SSHServer: SSH Server name
    • SSHUser: SSH User name
    • SSHPassword: SSH Password

    SSH Connections to PostgreSQL in Public Key Auth Mode

    To connect to PostgreSQL via SSH in Password Auth mode, set the following connection properties:

    • User: PostgreSQL User name
    • Password: PostgreSQL Password
    • Database: PostgreSQL database name
    • Server: PostgreSQL Server name
    • Port: PostgreSQL port number like 3306
    • UserSSH: "true"
    • SSHAuthMode: "Public_Key"
    • SSHPort: SSH Port number
    • SSHServer: SSH Server name
    • SSHUser: SSH User name
    • SSHClientCret: the path for the public key certificate file

  6. Click Save & Test
  7. Navigate to the Permissions tab in the Add PostgreSQL Connection page and update the User-based permissions. πŸ‘ 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. πŸ‘ 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 PostgreSQL data from datapine.

Connecting to PostgreSQL from datapine

Once you configure your connection to PostgreSQL in Connect AI, you are ready to connect to PostgreSQL from datapine.

  1. Log into datapine
  2. Click Connect to navigate to the "Connect" page
  3. Select MS SQL Server as the data source
  4. In the Integration step, fill in the connection properties and click "Save and Proceed"
    • Set the Internal Name
    • Set Database Name to the name of the connection we just configured (e.g. PostgreSQL1)
    • Set Host / IP to "tds.cdata.com"
    • Set Username to your Connect AI username (e.g. [email protected])
    • Set Password to the corresponding PAT
    • Set Database Port to "14333"
    πŸ‘ Configuring the connection to CData Connect AI
  5. In the Data Schema step, select the tables and fields to visualize and click "Save and Proceed" πŸ‘ Selecting tables and fields to visualize (Salesforce is shown)
  6. In the References step, define any relationships between your selected tables and click "Save and Proceed" πŸ‘ Defining foreign key relationships
  7. In the Data Transfer step, click "Go to Analyzer"
