The need to support multiple views of complex software architectures, each capturing a different aspect of the system under development, has been recognized for a long time. Even the very first object-oriented analysis/design methods such as the Booch method and OMT supported a number of different diagram types (e.g. structural, behavioral, operational) and subsequent methods such as Fusion, Kruchten’s...
This talk will deal with the practical experiences of large-scale deployment of Model Driven Engineering practises within parts of the Ericsson development organisation. We try to present a balanced argument in favour of why Model Driven Development is a powerful concept in large-scale engineering projects, but also cover many of its nasty aspects and attempt to reason upon the nature of these failings...
The use of Feature Models (FMs) to define the valid combinations of features in Software Product Lines (SPL) is becoming commonplace. To enhance the scalability of FMs, support for composing FMs describing different SPL aspects is needed. Some composition operators, with interesting property preservation capabilities, have already been defined but a comprehensive and efficient implementation is still...
Current mobile digital communication systems must implement rigorous operations to guarantee high levels of confidentiality and integrity during transmission of critical information. To achieve higher performance, the security algorithms are usually implemented as dedicated hardware functional units attached to the main processing units of the embedded communication system. To save hardware resources,...
Successful application of model-driven engineering approaches requires interchanging a lot of relevant data among the tool ecosystem employed by an engineering team (e.g., requirements elicitation tools, several kinds of modeling tools, reverse engineering tools, development platforms and so on). Unfortunately, this is not a trivial task. Poor tool interoperability makes data interchange a challenge...
Many crosscutting concerns in business processes need to be addressed already at the business process modeling level such as compliance, auditing, billing, and separation of duties. However, existing business process modeling languages including OMG’s Business Process Modeling Notation (BPMN) lack appropriate means for expressing such concerns in a modular way. In this paper, we motivate the need...
A reflective approach to model-driven web engineering is presented, which aims to overcome several of the shortcomings of existing generative approaches. The approach uses the Epsilon platform and Apache Tomcat to render dynamic HTML content using Epsilon Generation Language templates. This enables EMF-based models to be used as data sources without the need to pre-generate any HTML or dynamic script,...
Requirements analysis based on Problem Frames is getting an increasing attention in the academic community and has the potential to become of relevant interest also for industry. However the approach lacks an adequate notational support and methodological guidelines, and case studies that demonstrate its applicability to problems of realistic complexity are still rare. These weaknesses may hinder...
Domain Specific Modeling Languages (DSML) are more and more used to handle high level concepts, and thus bring complex software development under control. The increasingly recurring definition of new languages raises the problem of the definition of support tools such as editor, simulator, compiler, etc. In this paper we propose generative technologies that have been designed to ease the development...
Implementing static analyses of machine-level executable code is labor intensive and complex. We show how to leverage model-driven engineering to facilitate the design and implementation of programs doing static analyses. Further, we report on important lessons learned on the benefits and drawbacks while using the following technologies: using the Scala programming language as target of code generation,...
OMG’s SPEM – by means of its (semi-)formal notation – allows for a detailed description of development processes and methodologies, but can only be used for a rather coarse description of their behavior. Concepts for a more fine-grained behavior model are considered out of scope of the SPEM standard and have to be provided by other standards like BPDM/BPMN or UML. However, a coarse granularity of...
Domain-specific modelling (DSM) environments enable experts in a certain domain to actively participate in model-driven development. Developing DSM environments need to be cost-efficient, since they are only used by a limited group of domain experts. Different model-driven technologies promise to allow this cost-efficient development. [1] presented experiences in developing a DSM environment for telecommunication...
With increasing complexity of software in today’s products, writing and maintaining thousands of lines of code is a tedious task. Instead, an alternative methodology must be employed. Model-based development is one candidate that offers several benefits and allows engineers to focus on the domain of their expertise than writing huge codes. In this paper, we discuss the application of model-based development...
Dynamic UML models like sequence diagrams (SD) lack sufficient formal semantics, making it difficult to build automated tools for their analysis, simulation and validation. A common approach to circumvent the problem is to map these models to more formal representations. In this context, many works propose a rule-based approach to automatically translate SD into colored Petri nets (CPN). However,...
Model Driven Engineering (MDE) and constraint programming (CP) have been widely used and combined in different applications. However, existing results are either ad-hoc, not fully integrated or manually executed. In this article, we present a formalization and an approach for automating constraint-based solving in a MDE platform. Our approach generalizes existing work by combining known MDE concepts...
Today, developments of Real Time Embedded Systems have to face new challenges. On the one hand, Time-To-Market constraints require a reliable development process allowing quick design space exploration. On the other hand, rapidly developing technology, as stated by Moore’s law, requires techniques to handle the resulting productivity gap. In a previous paper, we have presented our Model Based Engineering...
Version management of business process models requires that changes can be resolved by applying change operations. In order to give a user maximal freedom concerning the application order of change operations, position parameters of change operations must be computed dynamically during change resolution. In such an approach, change operations with computed position parameters must be applicable on...
Multi-View Modeling (MVM) is a common modeling practice that advocates the use of multiple, different and yet related models to represent the needs of diverse stakeholders. Of crucial importance in MVM is consistency checking — the description and verification of semantic relationships amongst the views. Variability is the capacity of software artifacts to vary, and its effective management is a core...
This paper describes a model-based method to evaluate performance of embedded systems. The core technology of this modeling method is reverse modeling based on dynamic analysis of the existing systems. A case study of real MFPs (multifunction peripherals/printers) is presented in this paper to evaluate the modeling method.
