Integrate with Azure Data Catalog Data in JReport Designer

The CData JDBC Driver for Azure Data Catalog data enables access to live data from dashboards and reports as if Azure Data Catalog were a relational database, allowing you to query Azure Data Catalog data using familiar SQL queries. This article shows how to connect to Azure Data Catalog data as a JDBC data source and create reports based on Azure Data Catalog data in JReport Designer.

Connect to Azure Data Catalog Data

1. Edit C:\JReport\Designer\bin\setenv.bat to add the location of the JAR file to the ADDCLASSPATH variable:

   ...
   set ADDCLASSPATH=%JAVAHOME%\lib\tools.jar;C:\Program Files\CData\CData JDBC Driver for Azure Data Catalog 2016\lib\cdata.jdbc.azuredatacatalog.jar;
   ...
   

2. Create a new data source by clicking File New Data Source.
3. In the resulting dialog, create a name for the data source (CData JDBC Driver for Azure Data Catalog), select JDBC, and click OK.
4. In the Get JDBC Connection Information dialog you will configure your connection to the JDBC driver:
   • Driver: Be sure that the Driver box is checked and fill in the name of the class for the driver: cdata.jdbc.azuredatacatalog.AzureDataCatalogDriver
   • URL: Enter the JDBC URL. This starts with jdbc:azuredatacatalog: and is followed by a semicolon-separated list of connection properties.

     You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

     CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

     Connect Using OAuth Authentication

     You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.azuredatacatalog.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:azuredatacatalog:InitiateOAuth=GETANDREFRESH
   • User: The username to authenticate with; typically left blank.
   • Password: The password to authenticate with; typically left blank.

5. In the Add Table dialog, select the tables you wish to include in your report (or in future reports using this data source) and click Add.

   Click Done once the dialog has completed loading the tables.

6. In the Catalog Browser, you can create the queries that you will use to populate your reports. You can do this now, or after you create your report. In either case, expand () the data source (CData JDBC Driver for Azure Data Catalog), right-click on Queries, and select Add Query.
7. In the Add Table/View/Query dialog, expand () the JDBC URL and Tables and select the table(s) you wish to use in the query and click OK.
8. In the Query Editor dialog, you can select the columns you wish to include or simply click the SQL button and manually input your own query. For example:

   SELECT DslAddressDatabase, Type FROM Tables WHERE Name = 'FactProductInventory'
   

   With the query built, click OK to close the Query Editor dialog. At this point you are ready to add Azure Data Catalog data to a new or existing report.

   NOTE: Now that the query is built, you can create a Business View based on the query. With a Business View, you can create Web reports or library components based on the query. For more information on this, refer to the JReport tutorials.

Add Azure Data Catalog Data to a Report

You are now ready to create a report with Azure Data Catalog data.

1. Create a new report (File New Page Report) or open the Chart Wizard for an existing report.
2. Select the Query (or create a new one; see above).
3. Assign a Category and Value for the chart from the columns in your Query and click Finish.
4. Click the View tab for your report to see the chart.
