In practice, automatic Abstract— The models transformation is the fundamental transformation begins from PIM to PSM. However, our key in Model Driven Architecture approach. In Model Driven ultimate aim is to make the CIM a productive level, and a Architecture there are two transformations kinds: the CIM to basis for building PIM through an automatic transformation. PIM transformation and the PIM to PSM transformation. The researchers focused on the transformation from PIM level to The goal is that business models do not remain only simple PSM level, because there are several points in common between documents of communication between business experts and these two levels. However, the transformation from CIM level software designers. to PIM level is rarely discussed in research subjects because In this paper, we present a solution for automating they are two completely different levels. This paper proposes a transformation from CIM level business-based to the PIM model transformation method to master the transformation level web-based. However, we use UML 2 activity diagram from CIM to PIM web-based in accordance with the Model Driven Architecture approach. Indeed, the main value of this to attain concentrated CIM models, which simplifies the method is to propose a transformation from business-oriented transformation to PIM level. Then, we define a set of models to web-oriented models. This method is founded on selected-rules for automating the transformation from CIM building a good CIM level via well-defined rules, allowing us to to PIM. win precious models that facilitate the task of the Our approach is based on UML 2 [2] activity diagram transformation from CIM to PIM web-based. Then, we define a ,which represents one of standards of business model, for set of well- selected rules to move from CIM to PIM web-based so as to ensure a semi-automatic transformation. This method define the CIM level. Then rich business models of well- conforms to MDA recommendations by considering the concentrated information help us to obtain easily models of business dimension in the CIM level, and by modeling this PIM level. First model of PIM level is use case diagram latter level using UML activity diagram which is one of OMG model allows modeling functionalities of the system. Then, standards for modeling business process. Nevertheless, we used the state diagram model defines the states of information UML models into the PIM level, because UML is recommended system. Next, package diagram model allows modeling by MDA in this level. system classes and their relationships independently of a Index Terms— MDA, computer model, CIM, PIM, business programming language, and allows organizing all classes process modeling, model transformation, computer modeling, inside packages. However, these design models contain the business model, web model, web modeling necessary and sufficient information for building web model. Rest of this paper is presented as follows.

    Sysml Distilled: a Brief Guide to the Systems Modeling Language

    ptg11539604 Praise for SysML Distilled “In keeping with the outstanding tradition of Addison-Wesley’s techni- cal publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engi- neers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distin- guishing the subtle differences between use cases and scenarios to illu- mination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” — Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disci- plines and across the development life cycle. Many languages have the ptg11539604 potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many do- mains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” — Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML.

Lano, T. Clark, S. Kolahdouz-Rahimi Dept. of Informatics, King's College London; Dept. of Informatics, Middlesex University Abstract. A model transformation verification task may involve a number of different trans- formations, from one or more of a wide range of different model transformation languages, each transformation may have a particular transformation style, and there are a number of different verification properties which can be verified for each language and style of transfor- mation. Transformations may operate upon many different modelling languages. This diver- sity of languages and properties indicates the need for a suitably generic framework for model transformation verification, independent of particular model transformation languages, and able to provide support for systematic procedures for verification across a range of languages, and for a range of properties. In this paper we describe the elements of such a framework, and apply this framework to a range of transformation verification problems.
  • Model Transformation Design Patterns

    Model Transformation Design Patterns

    Model Transformation Design Patterns Hüseyin Ergin [email protected] Department of Computer Science, University of Alabama, U.S.A. Abstract. In this document, a brief overview of my doctoral research is pre- sented. In model-driven engineering (MDE), most problems are solved using model transformation. An efficient process to solving these problems is to apply reusable patterns while solving them. Finding reusable design patterns to specific subsets of problems helps to decrease the time and cost needed to solve them. My doctoral research is based on finding these design patterns to be applied on model transformation problems and evaluating them in terms of quality criteria. My next step is to generate these design pattern instances automatically by using higher-order transformation. 1 Introduction Model-driven engineering (MDE) [1] is considered a well-established software devel- opment approach that uses abstraction to bridge the gap between the problem and the software implementation. These abstractions are defined as models. Models are primary artifacts in MDE and are used to describe complex systems at multiple levels of abstrac- tion, while capturing some of their essential properties. These levels of abstraction let domain experts describe and solve problems without depending on a specific platform or programming language. Models are instances of a meta-model which defines the syntax of a modeling lan- guage. In MDE, the core development process consists of a series of transformations over models, called model transformation. Model transformations take models as input and output according to the specifications defined by the meta-model. In this document, I summarize the subject that I want to work on in my dissertation.
