Trident Genesis (TG) is a software development technology, which has been developed by a bunch of dedicated individuals from Ukraine and Australia with a financial support of Fielden Management Services Pty. Ltd.
In essenсe, TG incapsulates accidental complexity in order to enable application developers to better harness the essential complexity that stems from the target business domain.
We've built TG for our own purpose to remove many low level technical obstacles (accidental complexity) that are often associated with building sophisticated transactional applications such as Enterprise Asset Maintenance (EAM) or Enterprise Resource Planning (ERP) systems. And we have successfully used TG for developing large-scale and mission-critical enterprise applications.
We look at the system design as the decomposition problem, which can be solved successfully with the right approach in the right context. TG establishes a well defined pattern for modelling business domains, including domain entities, processes and their interdependencies (down to the level of properties with automatic revalidation support). At the code level the description of the domain model is achieved by using a small set of base classes and various annotations. Together these constitute what we refer to as "Entity Definition Language" (EDL), which is complemented by "Entity Query Language" (EQL) for data querying (relational databases).
Both EDL and EQL form the foundation of TG -- the rest is built on top it. We've used this foundation to build Swing-based applications at first. And now the same foundation is used for delivering responsive Polymer-based HTML5 single-page applications and GraphQL-based Web API. Such seamless transition was a testimony for ourselves that the foundation of TG is indeed robust and such that can successfully evolve to fit the ever-changing landscape of surrounding technologies.
The notion of using of a single programming language for building TG-based applications was very important to us. That is why TG includes a domain-specific language for defining Web UI in Java. The business model is at the core of Web UI where editors and actions are derived based on the type information that is captured by the model. So, it is very much declarative. A quick illustration of the Web UI that can be produced this way is provided below.
One of the very important aspect of any technology is the documentation and demo applications that could be used for learning. Currently, all our applications are propriatery and their source cannot be shared.
The documentation forms part of this repository (LaTeX documents in platform-docsuch as https://github.com/fieldenms/tg/blob/develop/platform-doc/doc/tg-overview/tg-overview.tex and Wiki pages). However, these are mainly the overview-type documents and design sketches. A more training-oriented documentation is in the works and will be inlined with a demo business domain for building a smaller-size demo application.
We're at a very early stage of open-sourcing the TG platform and there was a lot of deliberation if this is even necessary. However, we feel that our needs are not unique and that our effort can be helpful to others out there. We owe it to the vibrant open-source community who worked hard on their projects and libraries that we use in our day-to-day work in developing the TG platform.
There are very exciting plans regarding the future TG development directions, which include, but are not limited to advanced static typing of the domain models, asynchronous EQL execution engine and self-tuning, real-time messaging and on and on. And we look forward to close collaboration with some you in the future!
