Description
EMMA is a framework designed to build a family of configurable systems, with emphasis on extensibility and flexibility. It is based on a loosely coupled, event driven architecture. The architecture relies on asynchronous communicating components as a basis for decomposition of the system.
EMMA is embracing a fine-grained, component-based architecture, which produces a network of communicating processes organized into components. Components are identified based on the cohesion criterion– the drive to keep related code and functionality grouped together. Each component is independent and can evolve internally as long as its functionality boundaries and external interface remain unchanged. Components are short lived, created for the duration of running a particular system, with the same or different set of components (configuration) for different applications. A component has a set of properties that can be initialized to required values and dynamically modified to alter the behavior of the particular component at run-time.
The system is in nature decentralized with each component accessing its own DAQ hardware or data stores and components communicating over a simple and efficient middleware implemented as a software bus.
The functionality of each application is orchestrated by scripts. Several different scripts can execute on a given set of components providing different behaviors, with each script parameterized to provide an easy way to tailor the application’s behavior.
The EMMA framework has been built upon the premise of composing test systems from independent components. It opens up opportunities for reuse of components and their functionality and composing them together in many different ways. It provides the developer with a lightweight alternative to microservices, while sharing their various advantages, including composability, loose coupling, encapsulation, and reuse.
