When concept drift is detected, the current model is no longer up-to-date and must be replaced by a new one to restore prediction accuracy. [11] [12] A shortcoming of reactive approaches is that performance may decay until the change is detected. Tracking solutions seek to track the changes in the concept by continually updating the model.
Architectural Model contains a definition of an architectural model from the University of Ottawa's Object Oriented Software Engineering database. Architectural Tradeoff Analysis Method (ATAM) is a method by which architecture can be evaluated for suitability and fit to requirements.
This abstraction promotes simpler models with a greater focus on problem space. Combined with executable semantics this elevates the total level of automation possible. The Object Management Group (OMG) has developed a set of standards called Model-Driven Architecture (MDA), building a foundation for this advanced architecture-focused approach.
Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. Model Driven Architecture is a kind of domain engineering, and supports model-driven engineering of software systems.
Software rot (bit rot, code rot, software erosion, software decay, or software entropy) is the degradation, deterioration, or loss of the use or performance of software over time. From a software user experience perspective, it is operating environmental evolution inclusive of hardware.
ARCADIA, a model-based engineering method for systems, hardware and software architectural design. ARCADIA ( Arc hitecture A nalysis & D esign I ntegrated A pproach) is a system and software architecture engineering method based on architecture-centric and model-driven engineering activities.
Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. There are two fundamental laws in software architecture: [3] [4] Everything is a trade-off "Why is more important ...
In software engineering, the use of models is an alternative to more common code-based development techniques. A model always conforms to a unique metamodel. One of the currently most active branches of Model Driven Engineering is the approach named model-driven architecture proposed by OMG.
