Integrate Placid Data in the Pentaho Report Designer

The CData JDBC driver for Placid data enables access to live data from dashboards and reports. This article shows how to connect to Placid data as a JDBC data source and publish reports based on Placid data in Pentaho.

Connect and Create a Report

1. Copy the JAR file of the driver, located in the lib subfolder of the installation directory, to the \Report-Designer\lib\jdbc\ folder in the Pentaho directory.
2. Run the report-designer.bat file in the \Report-Designer\ folder to open the Report-Designer UI.

3. Create a new data source with the driver by clicking Data -> Add Data Source -> Advanced -> JDBC (Custom) and then creating a new Placid connection. In the resulting dialog, configure the connection properties as shown below.

   • Custom Connection URL property: Enter the JDBC URL. This starts with jdbc:api: and is followed by a semicolon-separated list of connection properties.

     Placid uses API Key authentication to control access to the API. API tokens are project-specific and can be obtained from your project settings on placid.app.

     Using API Key Authentication

     To obtain your API key, log in to placid.app, navigate to your project, open the project settings, and generate an API token from the API section. Note that each API token is scoped to a specific project.

     After setting the following connection properties, you are ready to connect:

     • AuthScheme: Set this to APIKey.
     • APIKey: Set this to your Placid project API token.

     Example connection string:

     Profile=C:\profiles\Placid.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_project_api_token';
     

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Placid JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.api.jar
     

     Fill in the connection properties and copy the connection string to the clipboard.

     

     When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

     Below is a typical JDBC URL:

     jdbc:api:Profile=C:\profiles\Placid.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_project_api_token';

   • Custom Driver Class Name: Enter cdata.jdbc.api.APIDriver.
   • User Name: The username to authenticate with.
   • Password: The password to authenticate with.
   

Add Placid Data to a Report

You are now ready to create a report with Placid data.

1. Add the Placid source to your report: Click Data -> Add Data Source -> JDBC and select the data source.

2. Configure the query. This article uses the one below:

   SELECT ,  FROM Collections WHERE  = ''

   
3. Drag a chart onto your report and double-click it to edit the chart. Run the report to display the chart. You can use the results of this query to create a simple chart for the Collections table.
4. Finally, run the report to see the chart.
