This article presents a model for describing the architecture of software-intensive systems, based on the useof multiple, concurrent views. This use of multiple views allows to address separately the concerns of thevarious ‘stakeholders’ of the architecture: end-user, developers, systems engineers, project managers, etc.,and to handle separately the functional and non functional requirements. Each of the five views is described,together with a notation to capture it. The views are designed using an architecture-centered, scenario-driven, iterative development process.
Visuelle Modelle machen komplexe Systeme und Abläufe erfassbar. Modelle helfen Zusammenhänge darzustellen. Aber Modelle sind viel mehr als Bilder.
Visual Paradigm Suite ist die umfassende Umgebung für Modellierung und Softwareentwicklung. Sie unterstützt alle aktuellen Standardnotationen - UML 2.1, BPMN, SysML, ER-Diagramme und andere.
Vergleichbar mit BPMS werden nicht alle Anwender diese komplexe Funktionalität eines BRMS in gleichem Umfang nutzen. Entscheiden für einen Einsatz eines komplexen Management von Geschäftsregeln ist die Komplexitiät der Regeln. Grundsätzlich entscheidend für den Einsatz von regelbasierten Prozessen ist ja immer noch, wieviele Prozesse automatisierte werden können/müssen, wie komplex diese Prozesse sind und wie “teuer” es ein Unternehmen kommt, diese Prozesse nicht zu automatisieren. Entscheidend für den Einsatz eines ausgewachsenen BRMS ist deshalb immer noch, wie schnell ein Unternehmen auf Veränderungen am Markt reagieren können muss, wie agil ein Unternehmen sein muss.
Have you ever evolved your metamodel in EMF and your models were no longer valid afterwards? Or have you avoided to evolve your metamodel in order not to invalidate your models? Or have you even deteriorated your metamodel so that it remains downwards compatible to previous versions in order to avoid these problems?
This site introduces COPE, a tool based on EMF that eases the migration of models in response to an evolving metamodel. COPE explicitly records the history of the metamodel as a sequence of changes and allows to attach information of how to migrate models (which is referred to as coupled evolution). The attached information can be used to automatically migrate models to the new version of the metamodel. COPE even goes one step further and allows to reuse combinations of metamodel adaptation and model migration steps across metamodels.
In order not to disturb EMF users in their habits, COPE seamlessly integrates into the Ecore editor. A demonstration of the tool in action can be looked at here. It is planned to contribute COPE to the Eclipse community.
Many resources - books, magazine articles, and web sites - focus on how to work with the artifacts of the Unified Modeling Language (UML) as well as other modeling techniques. These resources introduce you to various modeling artifacts, describe a methodology for applying the artifacts in practice, or describe how to apply patterns and strategies for creating better models. Unfortunately few of these resources touch on the subject of style and when they do they rarely devote little space to it. This includes my own book, The Object Primer 3/e, which provides an excellent overview of UML artifacts (as well as a few others because the UML isn't sufficient for real-world development) and how to take them all the way to Java code and a relational database on the back end.
