COLA is the abbreviation of Clean Object-Oriented and Layered Architecture, which stands for "Clean Object-Oriented and Layered Architecture." At present, COLA has developed to COLA 4.0. COLA is divided into two parts, COLA architecture and COLA components. The meaning of architecture is the structure of elements. The COLA architecture was born for this purpose, and its core responsibility is to define a good application structure and provide the best practice of the best application architecture. Through continuous exploration, we found that a good hierarchical structure and a good package structure definition can help us manage the chaotic business application system. After many iterations, we have defined a relatively stable and reliable application architecture. Good application architectures all follow some common patterns.

A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.

Umple is technology for Model-Oriented Programming. It adds abstractions such as UML associations, attributes, and state machines to object-oriented programming languages such as Java, C++, PHP and Ruby. A developer can use Umple in one of several ways. They can start with a pure model, containing only classes, associations, attributes and state machines, and then gradually add methods in one of the base languages to the Umple code base. Alternatively a developer can start with a normal program in a language like Java, and add modeling constructs in very small increments, gradually moving their system from a code-centric system from a model-centric system. Either way, Umple provides top-quality code generation. Umple is being used, for real systems. In fact the Umple compiler itself was written in Umple. Any Java, C++ or PHP project could use Umple. The UmpleOnline web app provides a quick way to explore the Umple approach. It is at http://try.umple.org
