Provide current CSV data to your embedded analytics.

The CData JDBC Driver for CSV integrates connectivity to CSV APIs into your data-driven Java applications. You can use the CData JDBC Driver for CSV with the BIRT (Business Intelligence Reporting Tools) platform to create BIRT reports that reflect changes to your data in real time.

  1. If you have not already done so, install the BIRT Framework plugin and the Database Development plugin for Eclipse.
  2. Click File -> New -> Report. The Report Design perspective is opened.
  3. In the Data Explorer, right-click Data Sources and click New Data Source.
  4. Select the Create from a Data Source Type in the Following List option and select JDBC Data Source.
  5. Click Manage Drivers and add the driver JAR, located in the lib subfolder of the installation folder.
  6. In the Database URL box, enter the JDBC URL containing the connection string.

    Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) CSV Files

    CData Drivers let you work with CSV files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.

    Setting connection properties for local files

    Set the URI property to local folder path.

    Setting connection properties for files stored in Amazon S3

    To connect to CSV file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended CSV files exist. In addition, at least set these properties:

    • AWSAccessKey: AWS Access Key (username)
    • AWSSecretKey: AWS Secret Key

    Setting connection properties for files stored in Box

    To connect to CSV file(s) within Box, set the URI property to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect to Box.

    Dropbox

    To connect to CSV file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.

    SharePoint Online (SOAP)

    To connect to CSV file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended CSV file. Set User, Password, and StorageBaseURL.

    SharePoint Online REST

    To connect to CSV file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended CSV file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.

    Google Drive

    To connect to CSV file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.csv.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.

    A typical JDBC URL is below:

    jdbc:csv:URI=/PATH/TO/MyCSVFilesFolder;
    
  7. Right-click the Data Sets folder and select the JDBC data source for CSV.
  8. In the resulting dialog, build the SELECT query to be used to retrieve the data for the report. This article uses the following query:
    SELECT City, SUM(TotalDue) FROM Customer GROUP BY City
    
  9. In the Palette, drag a Chart onto the editor. The chart wizard is displayed.
  10. After selecting the chart type, drag columns onto the chart fields on the Select Data tab.
  11. Click Run -> View Report -> In Web Viewer to view the report.

Your BIRT reports can now pick up any updates to CSV data. 👁 A BIRT report that can be refreshed on demand. (Salesforce is shown.)

To publish the report to your application server, add the driver JAR to the BIRT Viewer's classpath. For more information, see the CData KB for guides to deploying the JDBC Driver on Java application servers.
