Design BIRT Reports on CouchDB Data

The CData JDBC Driver for CouchDB integrates connectivity to CouchDB APIs into your data-driven Java applications. You can use the CData JDBC Driver for CouchDB 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.

   Set the following to connect:

   • Url: The Url of your instance. For example: http://localhost:5984
   • User The Apache CouchDB user account used to authenticate.
   • Password The Apache CouchDB password associated with the authenticating user.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.apachecouchdb.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:apachecouchdb:Url=http://localhost:5984;User=abc123;Password=abcdef;
7. Right-click the Data Sets folder and select the JDBC data source for CouchDB.
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 MovieRuntime, MovieRating FROM Movies WHERE MovieRating = 'R'
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 CouchDB data.

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.
