KISS + Swing = RAD

How to rapidly develop enterprise class Swing applications by keeping things simple

It took less than five minutes to generate and since it's just Java Swing, it can easily be customized and extended for use in an application. You can see a detailed demo of XTT on JavaLobby. Tools like these can really kick your development into overdrive.

More Synergies: Combining Swing Frameworks with Object Databases
By combining a Swing framework with an object database, you can cover 80%-90% of your application's plumbing. Now you can focus on developing the user interface and business logic.

Visualizing Code Coverage
Figure 7 depicts using XTT with an object database, in this case InterSystems' Caché. The specific implementation will differ somewhat for other object databases and Swing frameworks. The purpose here is to illustrate what percent of the software stack we can address by using these technologies. Here XTT fully addresses the presentation layer, data binding, and data transport layers of the application. Note that XTT can bind directly to the SQL/relational interface of the database or to POJOs that are then synchronized with objects on the server. In this configuration, developers only have work with objects on both the client and server and data persistence from the client is automatically handled by XTT.

Summary
By using object databases, Swing, and Swing binding/transport frameworks you can reduce the plumbing code you develop by up to 80%-90% for the typical enterprise application. Each database and framework provides its own unique functionality and features and should be evaluated to see which best meets your needs - but most of them can significantly reduce the amount of code you have to develop and maintain. With 80% less code to write, you're well on your way to RAD.

Swing on the Desktop
There's been a lot of noise about Swing making a comeback on the desktop lately. Performance concerns are a thing of the past and new projects like the Java Desktop Integration Components (JDIC), Java Desktop Network Components (JDNC), Data Binding, and SwingX are adding much needed capabilities to Swing that improve the user experience and simplify development by providing much needed functionality in easy to use libraries. This, continuing our theme of simplification, saves you from writing and maintaining your own code.

Development Simplification rules of Thumb

  • Always survey the market before starting a new project to see what new technologies and frameworks can be used to simplify your development effort.
  • Use an object database to eliminate the work and overhead of mapping frameworks.
  • Limit the number of layers and technologies your application uses. It will reduce complexity and simplify maintenance.
  • Use frameworks based on open standards to provide the "plumbing" of your application so you can focus on the custom business logic. The frameworks should:
    - Be based on open standards => Therefore they will be supportable and extendable
    - Replace role-your-own "plumbing" => Reducing the code you write and maintain
    - Provide advanced features/functionality => Features you may not have the time or expertise to develop in-house.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities. Well-poised organizations, marketing smart devices with AI and BlockChain capabilities prepare to refine compliance and regulatory capabilities in 2018. Volumes of health, financial, technical and privacy data, along with tightening compliance requirements by...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
