Pentaho Analytics for MongoDB Cookbook

By: Joel André Latino, Harris Ward

Overview of this book

MongoDB is an open source, schemaless NoSQL database system. Pentaho as a famous open source Analysis tool provides high performance, high availability, and easy scalability for large sets of data. The variant features in Pentaho for MongoDB are designed to empower organizations to be more agile and scalable and also enables applications to have better flexibility, faster performance, and lower costs. Whether you are brand new to online learning or a seasoned expert, this book will provide you with the skills you need to create turnkey analytic solutions that deliver insight and drive value for your organization. The book will begin by taking you through Pentaho Data Integration and how it works with MongoDB. You will then be taken through the Kettle Thin JDBC Driver for enabling a Java application to interact with a database. This will be followed by exploration of a MongoDB collection using Pentaho Instant view and creating reports with MongoDB as a datasource using Pentaho Report Designer. The book will then teach you how to explore and visualize your data in Pentaho BI Server using Pentaho Analyzer. You will then learn how to create advanced dashboards with your data. The book concludes by highlighting contributions of the Pentaho Community.

Using a BeanShell data source

In this recipe, we are going to create a BeanShell data source, just as we did in previous reporting recipes. This BeanShell data source, a lightweight scripting for Java (http://www.beanshell.org), will allow us to query data from MongoDB.

Getting ready

To get ready for this recipe, you first need to start the MongoDB server with the same database as that of the last chapter. You will also need to start the Pentaho BA Server using the server control scripts. Once it is started, you should be able to log in to the BI Server.

How to do it…

Proceed with the following steps:

  1. In the PUC, navigate to File | New | CDE Dashboard.

  2. Click on the Data Sources tab.

  3. Expand the SCRIPTING Queries data source category.

  4. Click on the Scriptable over Scripting data source.

  5. Set the Name property to QUERY2.

  6. Set the Language property to beanshell.

  7. Click on the Query Editor button.

  8. Copy and paste the following BeanShell script:

    import com.mongodb.*;
import org.pentaho.reporting.engine.classic...
