Image Not Found.

Get started with OpenDDS, Object Computing's open source implementation of the Object Management Group's (OMG's) data distribution service (DDS), with this introductory course for Java developers.


The OMG Data Distribution Service (DDS) for real-time systems is a publish-and-subscribe middleware service designed to meet the performance, scalability, and quality-of-service needs of real-time and embedded systems.

OpenDDS is an open source implementation of the DDS specification with Java and C++ language bindings.

This course provides students with an overview of the DDS specification, an introduction to the OpenDDS implementation, and hands-on experience developing applications using OpenDDS in Java.


  • Understand the DDS’s role in developing distributed applications
  • Define custom DDS data types using OMG's interface definition language (IDL)
  • Develop and run DDS publishing and DDS subscribing applications
  • Become familiar with additional DDS features, including quality-of-service (QoS) policies, data instances, transports, discovery, listeners, conditions, wait sets, built-in topics, content-subscription, and security

2 days (6 hours)


The following topics are covered in this course:

  • Introduction to DDS
  • Defining DDS types with interface definition language (IDL)
