Data Distribution Service (DDS) is a publish-subscribe based data-centric middleware that enables the exchange of data in distributed systems, such as real-time systems, Internet of Things (IoT), and machine-to-machine (M2M) communication. It is an open standard developed and maintained by the Object Management Group (OMG) that provides a common framework for enabling data exchange between devices and applications in a distributed environment.
One of the main features of DDS is its ability to provide real-time communication and data dissemination, which makes it well-suited for use in systems that require low latency and high reliability. DDS also supports various QoS (Quality of Service) policies, such as reliability, durability, and security, which allow developers to tailor the performance and behavior of the system to meet the requirements of their specific application.
One of the key benefits of DDS is its ability to scale to large distributed systems with thousands of devices and applications. It uses a publish-subscribe model, where publishers send data to a central entity called a "data-centric router" or "data-centric bus," and subscribers receive data from this central entity. This allows for the efficient distribution of data to multiple recipients, as well as the ability to filter and process data at the central entity before it is sent to subscribers.
DDS is also designed to be flexible and interoperable, allowing it to be used in a wide range of applications and environments. It supports various programming languages and platforms, and can be integrated with other technologies, such as cloud computing and edge computing.
In summary, DDS is a powerful data-centric middleware that enables real-time communication and data exchange in distributed systems. Its scalability, QoS policies, and interoperability make it a valuable tool for developers and organizations looking to build reliable and efficient distributed systems.

What’s in the DDS Standard?
The code above is just an made up example of inheritance, and properly not the best - I have edited it a bit and hopefully it makes more sense now. It automatically switches back to the primary when it recovers, too. The Real-time Publish-Subscribe Wire Protocol DDS Interoperability Wire Protocol Specification ensured that information published on a topic using one vendor's DDS implementation is consumable by one or more subscribers using the same or different vendor's DDS implementations. This enables customers to find failure points with a great degree of accuracy. Programmers using traditional message-centric middleware must write code that sends messages.

What is DDS?
RTI does not control the content posted by visitors to RTI Community Portal and, does not guarantee the accuracy, integrity, or quality of such content. Twin Oaks deliver a fully featured small foot print DDS solution. At the edge they can be used for high-speed real-time machine to machine communications. RTI is committed to open standards, open community source and open architecture. Our technology is often applied in mission-critical situations where human lives are at stake — in applications like air and missile defense, air traffic control, maritime traffic management, and search and rescue. It will discover the type of data being published or subscribed to.

What is Data Distribution Service (DDS)?
This is only an illusion; there is no global place where all the data lives. DDS is smart about sending just what it needs. It represents a communication plane: only the publishers and the subscribers attached to the same domain may interact. You are entirely responsible for all content that you upload, post, e-mail, transmit or otherwise make available via RTI Community Portal. The same concepts and APIs are provided in different programming languages allowing applications to exchange information across operating systems, languages, and processor architectures.

The RTI ConnextGetting Started Guidewill teach you core concepts and guide you through writing your first application examples. DDS introduces a virtual Global Data Space where applications can share information by simply reading and writing data-objects addressed by means of an application-defined name Topic and a key. The essence of data centricity is that DDS knows what data it stores and controls how to share that data. All together, the local stores give applications the illusion of having access to the entire global data space. When updates need to be fast, DDS sends multicast messages to update many remote applications at once.

Plus, the Data Distribution Service Toolkit works with RTI Connext Tools for integrating and debugging distributed applications. It simplifies the development of distributed systems by letting software developers focus on the specific purpose of their applications rather than the mechanics of passing information between applications and systems. For further information about ADLINK Technology please visit: eProsima is a company focused on high performance middleware. Integrating these systems DDS provides scalable access and distribution of information all the way to and within the cloud. All of these attributes are taken into consideration during the dynamic discovery and matching of DDS participants. It must be downloaded and installed separately.

There is no data-sharing across DDS domains. As data formats evolve, DDS keeps track of the versions used by various parts of the system and automatically translates. Retrieved November 9, 2016. This is based on a model from a OO perspective, and it is just intended as a quick example: And this is my initial datamodel in IDL - is done correctly? Updates to the carpool then happen via the car structures. Dynamic Discovery makes your DDS applications extensible.
