The Data Distribution Service (DDS) is a standard for efficient and ubiquitous data sharing built upon the concept of a, strongly typed, distributed data space. The ability to scale from resource constrained embedded systems to ultra-large scale distributed systems, has made DDS the technology of choice for applications, such as, Power Generation, Large Scale SCADA, Air Traffic Control and Management, Smart Cities, Smart Grids, Vehicles, Medical Devices, Simulation, Aerospace, Defense and Financial Trading.
This two part webcast provides an in depth introduction to DDS – the universal data sharing technology. Specifically, we will introduce (1) the DDS conceptual model and data-centric design, (2) DDS data modeling fundamentals, (3) the complete set of C++ and Java API, (4) the most important programming, data modeling and QoS Idioms, and (5) the integration between DDS and web applications.
After attending this webcast you will understand how to exploit DDS architectural features when designing your next system, how to write idiomatic DDS applications in C++ and Java and what are the fundamental patterns that you should adopt in your applications.
The Object Management Group (OMG) Data Distribution Service (DDS) and the OPC Foundation OLE for Process Control Unified Architecture (OPC-UA) are commonly considered as two of the most relevant technologies for data and information management in the Industrial Internet of Things. Although several articles and quotes on the two technologies have appeared on various medias in the past six months, there is still an incredible confusion on how the two technology compare and what’s their applicability.
This presentation, was motivated by the author's frustration with reading and hearing so many mis-conceptions as well as “apple-to-oranges” comparisons. Thus to contribute to clarity and help with positioning and applicability this webcast will (1) explain the key concepts behind DDS and OPC-UA and relate them with the reason why these technologies were created in the first place, (2) clarify the differences and applicability in IoT for DDS and OPC-UA, and (3) report on the ongoing standardisation activities that are looking at DDS/OPC-UA inter-working.
DDS is a very powerful technology built around a few simple and orthogonal concepts. If you understand the core concepts then you can really quickly get up to speed and start exploiting all of its power. On the other hand, if you haven’t grasped the key abstractions you might not be able to exploit all the benefits that DDS can bring.
This presentation provides you with an introduction to the core DDS concepts and illustrates how to program DDS applications. The new C++ and Java API will be explained and used throughout the webcast for coding examples thus giving you a chance to learn the new API from one of the main authors!

Reactive Data Centric Architectures with DDSAngelo Corsaro
An increasing number of Software Architects realise that data is the most important asset of a system and start embracing the Data-Centric revolution (datacentricmanifesto.org) - setting data at the centre of their architecture and modelling applications as "visitors" to the data. At the same time, architects have also realised how reactive architectures (reactivemanifesto.org) facilitate the design of scalable, fault-tolerant and high performance systems. Few architects have yet realised how reactive and data-centric architectures are two sides of the same coin and as such should always go together. This presentation explains why reactive data-centric architecture is the future and how the OMG DDS Standard is uniquely positioned to support this paradigm shift. A series of case studies will highlight how the data-centric revolution is being applied in practice and what measurable benefits it is providing.

John Park, Offering Manager, for IBM Cloud Data Services covers the touchstones for tomorrow’s information systems: data and integration. Stovepipe applications are no longer acceptable, and siloed data sources must evolve and open up to the full enterprise. All this in an environment where more is expected faster, and at a lower cost. If your GIS doesn’t watch out, it will be replaced by less capable alternatives that “fit better” into mainstream IT. But dashDB, a cloud-native offspring of DB2, can provide a bridge that keeps both sides happy. This session introduce this popular cloud data warehousing solution and illustrate how it works in concert with ArcGIS. You will learn about the built-in geospatial functions in dashDB and how you can easily use them to build applications rapidly. You’ll see an application that uses weather data and mobile application data to calculate insurance risk, detect potential fraud, and prevent damage.
DDS Advanced Tutorial - OMG June 2013 Berlin MeetingJaime Martin Losa
An extended, in-depth tutorial explaining how to fully exploit the standard's unique communication capabilities.Presented at the OMG June 2013 Berlin Meeting.
Users upgrading to DDS from a homegrown solution or a legacy-messaging infrastructure often limit themselves to using its most basic publish-subscribe features. This allows applications to take advantage of reliable multicast and other performance and scalability features of the DDS wire protocol, as well as the enhanced robustness of the DDS peer-to-peer architecture. However, applications that do not use DDS's data-centricity do not take advantage of many of its QoS-related, scalability and availability features, such as the KeepLast History Cache, Instance Ownership and Deadline Monitoring. As a consequence some developers duplicate these features in custom application code, resulting in increased costs, lower performance, and compromised portability and interoperability.
This tutorial will formally define the data-centric publish-subscribe model as specified in the OMG DDS specification and define a set of best-practice guidelines and patterns for the design and implementation of systems based on DDS.

Streaming Data Into Your Lakehouse With Frank Munz | Current 2022
The last years have taught us that cheap, virtually unlimited, and highly available cloud object storage doesn't make a solid enterprise data platform. Too many data lakes didn't fulfill their expectations and degenerated into sad data swamps.
With the Linux Foundation OSS project Delta Lake (https://github.com/delta-io), you can turn your data lake into the foundation of a data lakehouse that brings back ACID transactions, schema enforcement, upserts, efficient metadata handling, and time travel.
In this session, we explore how a data lakehouse works with streaming, using Apache Kafka as an example.
This talk is for data architects who are not afraid of some code and for data engineers who love open source and cloud services.
Attendees of this talk will learn:
1. Lakehouse architecture 101, the honest tech bits
2. The data lakehouse and streaming data: what's there beyond Apache Spark™ Structured Streaming?
3. Why the lakehouse and Apache Kafka make a great couple and what concepts you should know to get them hitched with success.
4. Streaming data with declarative data pipelines: In a live demo, I will show data ingestion, cleansing, and transformation based on a simulation of the Data Donation Project (DDP, https://corona-datenspende.de/science/en) built on the lakehouse with Apache Kafka, Apache Spark™, and Delta Live Tables (a fully managed service).

In the past few years we have experienced an amazing proliferation of mobile and embedded platforms. Contemporary developers are increasingly being faced with the challenge of writing applications that can run on desktop, mobile (e.g. Android and iOS), and on low-cost embedded platforms (e.g. Raspberry-Pi and Beaglebone). This is causing a rejuvenated interest in the Java platform as a means to achieve the holy grail of write-once and run-everywhere. With the availability of Java environments supporting almost any kind of device in several different form factors, the missing element of the picture is an effective way of enabling communication between them.

Spectra IP Core ORB - high-performance, low-latency solution for FPGA-GPP com...ADLINK Technology IoT
Various approaches have been developed for integrating FPGA and GPP application components in a Software Communications Architecture (SCA) radio. Most of these have been less than successful, primarily due to overhead, latency and/or maintainability issues. Spectra IP Core is a second-generation solution to FPGA-GPP component integration that provides a low-latency, standards-based CORBA protocol with excellent performance metrics and the robustness of a proven, deployed solution. Building on PrismTech’s ICO v1, Spectra IP Core is a second-generation COTS product. This webcast will introduce the Spectra IP Core architecture, its main functions and its performance benchmarks. Although FPGA ‘middleware’ is a new concept for many FPGA developers, the capabilities provided by Spectra IP Core not only provide valuable integration ‘hooks’, but also help support a highly-efficient, proven radio component that simplifies the integration of high-level software development with digital design and accelerates the development of SCA-compliant FPGA components for SCA radios. These slides will be of great interest and value to project managers, systems engineers and architects as well as software and digital engineers involved in designing, building and testing SCA-compliant SDRs.
Testing early on and throughout the development cycle reduces the risks that affect time to market, cost and software quality. By exercising components (application components, devices and services) at the beginning of the development cycle in a runtime environment, and by continuing to test, as components are refined, developers can be assured of continuous Software Communications Architecture (SCA) compliance up to development cycle completion. Spectra CX SCA Test can be used to test the software aspects that have been hand written, generated automatically using a Spectra CX Code Generator, or generated automatically using a 3rd party tool. Developers benefit from fully automated testing of all aspects of the SCA specified interfaces for each component.
These slides will demonstrate the steps for unit testing the standard SCA interfaces of an SCA component with Spectra CX SCA Test. Topics will include: introduction to the Spectra CX unit testing framework; generation of standard unit tests; execution of unit tests on-host and on-target; and creating custom test cases.

A DataReader can be bound to a user provided function that will handle
incoming data or to a cache
Notice, that as you are in control of how data-readers are bound to cache you
can be very creative
Binding a DataReader
50. CopyrightPrismTech,2014
Binding to a Cache
// Binding
bindCell = dds.bind((s) -> s.x + “-” + s.y)
ccache = new DataCache(historyDepth)
bindCell(ccache, cdr)
// Working with the Cache: Compute number of active cells
activeCells = ccache.map((c) -> if (c.pressure > p0) then 1 else 0).fold(0)
((a, c) -> a + c)
cache = new DataCache(historyDepth)
bind(keyMapper)(dr, cache)
CoffeeScript
Example:
51. CopyrightPrismTech,2014
DataCache Operations
# Writes a data sample into the cache corresponding to the key k
write: (k, data)
# Returns a list representing the content of the cache ordered by key.
read()
# Returns a list representing the last sample for each key
readLast()
# Returns a list representing the content of the cache ordered by key.
# The data is actually removed from the cache.
take()
# Returns a list representing the last sample for each key
# The data is actually removed from the cache.
takeLast()
52. CopyrightPrismTech,2014
DataCache Operations
# Returns a list representing the content of the cache that matches for given predicate.
# The data is actually removed from the cache.
takeWithFilter(p)
# Returns Some(v) if a value associated to the key k exists. Otherwise it returns None
get: (k)
# Returns Some(v) if a value associated to the key k exists. Otherwise it returns f()
getOrElse(k, f)
# Clear the content of the cache.
clear()
53. CopyrightPrismTech,2014
DataCache Operations
# Returns a new DataCache whose content is obtained by applying the function
# f to each element of the cache
map(f)
# Executes the function f on each element of the cache
forEach(f)
# Executes the function f only on the first n samples associated with a key
forEachN(f, n)
# Returns the element of the cache that match the predicate p
filter(p)
# Returns the element of the cache that do not match the predicate p
filterNot(p)
54. CopyrightPrismTech,2014
DataCache Operations
# Folds the content of the data cache using z as “zero” for the folding function f
# For instance, assuming that the operator “+” is defined for the elements of
# the cache, then you could compute the sum of all elements doing:
# c.fold(0)((a, v) -> a + v)
# the product by:
# c.fold(1)((a, v) -> a * v)
# a comma separated string representation of the content:
# c.fold(“”)(a, v) -> a + “, “ + v
fold(z)(f)
# Register a listener l to be notified whenever data which matches a
# predicate p is written into the cache. If no predicate is provided
# then the listeners is always notified upon data insertion.

To learn how to write an Android
Application that uses Vortex Café
we’ll develop a very simple Chat
To keep things simple this chat will
have a single “chat room”
DDS Chat for Android
77. CopyrightPrismTech,2014
Our Chat application will have a very simple architecture with simply one
Activity that will take care of:
- Sending Posts into the ChatRoom
- Displaying Posts in the room since when we joined
In terms of information modelling, we’ll have a single topic representing the user
post
Step 1: Architecture
struct Post {
string name;
string msg;
};
#pragma keylist Post name

Creating DDS entities, such as
DomainParticipants, DataReaders and
DataWriters involves network communication,
such as discovery information
In addition when an a DDS entity is destroyed it
looses its state
As such, tying the life-cycle of DDS entities to
activities should be done with great care
Step 2: Lifecycle Management[1/2]
79. CopyrightPrismTech,2014
In general, it is a better idea to tie the life-cycle of
DDS entities to the Application as opposed to
Activities
In some cases, it may make sense to tie the life-
cycle of DataReaders/DataWriters to that of the
activity that relies on them -- Usually this makes
sense for activities that are “one-off”

When using Vortex Café you need to grant the proper permissions for
networking:
More Manifest...
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE"/>

Receiving data is a bit trickier since in Android only the thread that runs an
activity has the right to change the UI
This means, that from a DDS listener it is not possible to change an the UI
directly!
The solution is to use an Android Handler to which we can post Runnable to
be executed by the activity thread
Let’s see how this works...
