Build Visualizations of DB2 Data in Birst

Birst is a cloud business intelligence (BI) tool and analytics platform that helps organizations quickly understand and optimize complex processes. When paired with the CData JDBC Driver for IBM DB2, you can connect to live DB2 data through the Birst Cloud Agent and build real-time visualizations. In this article, we walk you through, step-by-step, how to connect to DB2 using the Cloud Agent and create dynamic reports in Birst.

With powerful data processing capabilities, the CData JDBC Driver offers unmatched performance for live DB2 data operations in Birst. When you issue complex SQL queries from Birst to DB2, the driver pushes supported SQL operations, like filters and aggregations, directly to DB2 and utilizes the embedded SQL Engine to process unsupported operations client-side (often SQL functions and JOIN operations). With built-in dynamic metadata querying, the JDBC driver enables you to visualize and analyze DB2 data using native Birst data types.

Configure a JDBC Connection to DB2 Data in Birst

Before creating the Birst project, you will need to install the Birst Cloud Agent (in order to work with the installed JDBC Driver). Also, copy the JAR file for the JDBC Driver (and the LIC file, if it exists) to the /drivers/ directory in the installation location for the Cloud Agent.

With the driver and Cloud Agent installed, you are ready to begin.

1. Create a new project in Birst.
2. Name the connection (e.g. CDataDB2).
3. Choose Live Access.
4. Select an agent.
5. Set Database Type to Other.
6. Set SQL Type to MSSQL
7. Set the Connection string.

   Set the following properties to connect to DB2:

   • Server: Set this to the name of the server running DB2.
   • Port: Set this to the port the DB2 server is listening on.
   • Database: Set this to the name of the DB2 database.
   • User: Set this to the username of a user allowed to access the database.
   • Password: Set this to the password of a user allowed to access the database.

   You will also need to install the corresponding DB2 driver:

   • Windows: Install the IBM Data Server Provider for .NET.

     On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

   • Java: Install the IBM Data Server Driver for JDBC.

     In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the DB2 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.db2.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 connection string for DB2:

   jdbc:db2:Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;
8. Set the Driver Name: cdata.jdbc.db2.DB2Driver and click Save.

NOTE: Since authentication to DB2 is managed from the connection string, you can leave Security Credentials blank.

Configure DB2 Data Objects

Now that the connection is configured, we are ready to configure the schema for the dataset, choosing the tables, views, and columns we wish to visualize.

1. Select the Schema (e.g. DB2).
2. Click on Tables and/or Views to connect to those entities and click Apply.
3. Select the Tables and Columns you want to access and click Done.

With the objects configured, you can perform any data preparation and discover any relationships in your data using the Pronto Prepare and Relate tools.

Build a Visualization

After you prepare your data and define relationships between the connected objects, you are ready to build your visualization.

1. Select the Visualizer tool from the menu.
2. Select Measures & Categories from your objects
3. Select and configure the appropriate visualization for the Measure(s) you selected.
