Build AI/ML Models with Live OData Data using Dataiku



Connect OData Data with Dataiku using the CData JDBC Driver for OData.

Dataiku is a data science and machine learning platform used for data preparation, analysis, visualization, and AI/ML model deployment, enabling collaborative and efficient data-driven decision-making. When paired with the CData JDBC Driver for OData, Dataiku enhances data integration, preparation, real-time analysis, and reliable model deployment for OData services.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live OData services. When you issue complex SQL queries to OData, the driver pushes supported SQL operations, like filters and aggregations, directly to OData and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze OData services using native data types.

This article shows how you can easily integrate to OData using CData JDBC Driver for OData in Dataiku DSS (Data Science Studio) platform, allowing you to prepare the data and build custom AI/ML models.

About OData Data Integration

CData simplifies access and integration of live OData services data. Our customers leverage CData connectivity to:

  • Access OData versions 2.0, 3.0, and 4.0, working with legacy services and the latest features and capabilities.
  • Leverage advanced query options, including $filter, $select, and $expand, enhancing data retrieval from 3rd party tools.
  • Use Server-side execution of aggregation and grouping to minimize data transfer and boost performance.
  • Authenticate securely using a variety of schemes, including Azure AD, digest, negotiate, NTLM, OAuth, and more means secure authentication with every connection.
  • Use SQL stored procedures to manage OData service entities - listing, creating, and removing associations between entities.

Customers use CData's solutions to regularly integrate their OData services with preferred tools, such as Power BI, MicroStrategy, or Tableau, and to replicate data from OData services to their databases or data warehouses.


Getting Started


Preparing the Dataiku DSS environment

In this section, we will explore how to set up Dataiku, as previously introduced, with OData services. Be sure to install Dataiku DSS (On-Prem version) for your preferred operating system, beforehand.

Install the CData JDBC Driver for OData

First, install the CData JDBC Driver for OData on the same machine as Dataiku. The JDBC Driver will be installed in the following path:

C:\Program Files\CData[product_name] 20xx\lib\cdata.jdbc.odata.jar

Connecting the JDBC Driver in Dataiku DSS

To use the CData JDBC driver in Dataiku, you must create a new SQL database connection and add the JDBC Driver JAR file in the DSS connection settings.

  1. Log into Dataiku DSS platform. It should open locally in your browser (e.g. localhost:11200)
  2. Click on Navigate to other sections of Dataiku menu on the top right section of the platform and select Administration.
  3. Select the Connections tab.
  4. In Connections, click on New Connections button.
  5. Now, scroll down and select Other SQL databases.
  6. Generate a JDBC URL for connecting to OData, beginning with jdbc:odata: followed by a series of semicolon-separated connection string properties.

    The User and Password properties, under the Authentication section, must be set to valid OData user credentials. In addition, you will need to specify a URL to a valid OData server organization root or OData services file.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.odata.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    A typical JDBC URL is given below:

    jdbc:odata:URL=http://services.odata.org/V4/Northwind/Northwind.svc;UseIdUrl=True;OData Version=4.0;Data Format=ATOM;
  7. On the New SQL database (JDBC) connection screen, enter a name in the New connection name field and specify the basic parameters:
    • JDBC Driver Class: cdata.jdbc.odata.ODataDriver
    • JDBC URL: JDBC connection URL obtained in the previous step
    • Driver jars directory: the folder path where the JAR file is installed on your system

    Next, select the SQL dialect of your choice. Here, we have selected 'SQL Server' as the preferred dialect. Click on Create. If the connection is successful, a prompt will display, saying 'Connection OK'.

  8. The Data Catalog window will appear. Select the desired connection, catalog, and schema from the Connection to browse, Restrict to catalog, and Restrict to schema dropdowns, then click on List Tables. The Dataiku platform will list all the required tables.
  9. Select any table from the list and click Preview to view the table data. Click Close to exit the window.

Creating a new project

To prepare data flows, create dashboards, analyze the OData services, and build AI and ML models in the Dataiku DSS platform, you need to first create a new project.

  1. Select Projects from the Navigate to other sections of Dataiku menu.
  2. In the Projects screen, click New Project and select + Blank Project.
  3. In the New Project window, assign a Name and Project Key. Click Create. The new project dashboard opens up.
  4. Select Notebooks from the menu at the top of the project screen.
  5. Click on + Create Your First Notebook dropdown menu and select Write your own option.
  6. In the New Notebook window, select SQL.
  7. Now, select the required connection from the Connection dropdown and enter a name in the Notebook Name field.

Testing the connection

To test the OData connection and analyze the OData services, write a query in the query compiler and click Run. The queried/filtered OData services results will then appear on the screen.
