Today's Web Applications (WAs) are complex multi-user and multi-tenant software systems, used by users with different roles and often developed to support and manage complex business processes. Due to the changing nature of such processes, WAs need to be easily and quickly modified, to be adapted and aligned to the processes they support. In recent years, Model Driven Engineering (MDE) approaches have been used to support the development and the evolution of WAs. However, the definition of appropriate MDE approaches for the development of flexible process-centric WAs is still limited. In particular, flexible workflow models have never been integrated with the models used in MDE approaches to develop this type of applications. This paper proposes an MDE approach for the development and the evolution of flexible process-centric WAs that integrates four MDE metamodels used to represent the main components of a WA with the metamodel of Declare, a declarative language to model business processes. A case study, carried out to validate the feasibility, the correctness and the effectiveness of the proposed approach is presented and discussed.

The integration of domain-specific concepts in a model-driven engineering (MDE) approach raises a number of interesting research questions. There are two possibilities to represent these concepts. The first one focuses on models that contain domain-specific concepts only, i.e. domain-specific modelling languages (DSML). The second one advocates the integration of domain-specific concepts in general-purpose models, using what we will refer to in this paper as domain-specific modelling annotation languages (DSMAL). In this position paper, we argue that each approach is particularly suited for specific activities and specific actors, and show how they can be developed and used together. We also highlight the challenges created by the use of two representations, such as the evaluation of models OCL constraints and the synchronisation between the two representations. As an illustration, we present rbacUML, our approach for integrating role-based access control (RBAC) concepts into an MDE approach.

Hardware-in-the-loop (HIL) testing is an integral part of the development of power system automation solutions. HIL test beds facilitate system-level testing and validation of controllers against their specifications. The information required for HIL test bed configurations is typically scattered across different tools used in the development of power system automation solutions. These tools often have different formats and naming schemes. This implies that a significant effort is required for consolidating data from the tools and for creating valid test configurations from the consolidated data. This paper presents a Model-Driven Engineering (MDE) approach for creating HIL test configurations in a tool-, platform-, and protocol-agnostic manner. It shows how the MDE approach can be applied in practice to derive test configurations based on the information originating from different tools in a semi-automated fashion.

The specific requirements of developing Internet of Things (IoT) software for public transportation systems should be considered in addition to the problems always observed in IoT system development. After defining the problems encountered in the development of IoT-based public transport systems, the current model-driven engineering (MDE) approaches for IoT development are examined and their applicability for public transport systems is questioned in this paper. Several points of view are given about what new MDE approaches specific to this field should include in order to eliminate the identified deficiencies. Moreover, it is indicated that new MDE approaches should be designed including round-trip engineering to provide high mobility, use of special standards, in-vehicle communication networks and support for different system-on-chips in these public transportation systems.

During the last decade, Model Driven Engineering (MDE) has been proposed for supporting the development, maintenance and evolution of software systems. Model Driven Architecture (MDA), Software Factories and Eclipse Modeling Framework (EMF) are among the most representatives MDE approaches. Nowadays, it is well recognized that model transformation is at the heart of MDE approaches and, consequently represents one of the most important operations in MDE. However, despite the multitude of model transformation language proposals emerging from academic world and industry, these transformations are often manually specified; which is a tedious and error-prone task, and therefore an expensive process. Matching operation between metamodels is the keystone toward a (semi-)automatic transformation process. In this paper, the authors review metamodel matching techniques of the literature and then analyze their pros and cons in order to show how they can be useful for a semi-automatic transformation process. The result is a comparison of metamodel matching techniques, highlighting their similarities and differences in terms of information used for matching, demonstrating significant similarities between these techniques. Next, the authors compare four well-known metamodel matching techniques namely Similarity flooding, SAMT4MDE+ (extended Semi-Automatic Matching Tool for Model Driven Engineering), ModelCVS and AML (AtlanMod Matching Language) on ten couples of metamodels. For this comparison, the authors define a set of six criteria inspired from the database schema matching. One among these criteria is relevant to the quality of matching and for which we define a quality measure metrics. Furthermore, the authors develop a plug-in under Eclipse to support our comparison using ten couples of metamodels.

In the last years one of the main concerns of the software industry has been to reengineer their legacy Web Applications (WAs) to take advantage of the benefits introduced by Rich Internet Applications (RIAs). In this context, Model Driven (MD) Web Engineering approaches have been extended with new modeling primitives to obtain the benefits provided by RIA features. However, during the last decade, widespread language-specific Web frameworks have supported actual Web system development. In this paper we present a MD reverse engineering process to obtain a conceptual representation of the navigational concern of a legacy Web application (LWA), as an initial step within a LWA-to-RIA modernization process. WebML is selected as the target MD Web Engineering approach.

Model-Driven Engineering (MDE) is changing the way we build, operate, and maintain our software-intensive systems. Several projects using MDE practices are reporting significant improvements in quality and performance but, to be able to handle these projects, software engineers need a set of technical and interpersonal skills that are currently not widely available. The MDE postgraduate diploma intends to fill this gap by offering a full-time one year formation onMDE. The course syllabus is designed to teach students how to work at a higher abstraction level by the rigorous use of (software) models as the main artifacts in all software engineering activities. Contents include the conceptual framework of MDE plus all techniques and tools (e.g. for defining modeling languages, models, and model transformations) required to successfully complete software engineering projects following a MDE approach. The organizational impact (and challenges) of adopting MDE are exemplified using real industrial experiences. This article describes the MDE Diploma and the lessons that we learned after completing its first edition.

Defining low power design intent for a system-on-chip (SoC) consists in specifying its power management architecture and strategy according to specific low power techniques such as power gating and multi-voltage scaling requirements. Choosing the most-energy efficient power intent for a final system contributes widely to reduce its overall power consumption. At Transaction-Level, a rapid exploration of different power intent alternatives can be made. In this paper, we present a Model Driven Engineering (MDE) approach to automate low power design intent specifications and accelerate Low Power Design Intent Space Exploration (LPDISE) using a Transaction-Level power-aware design methodology. This MDE approach mainly relies on a high level abstraction of the Unified Power Format (UPF) standard concepts that fit a TLM approach use. Then, the MDE approach is applied to automatically generate a UPF code defining the most energy-efficient power intent and being a reference file for Register Transfer Level (RTL) design team. This task focuses on a smart deduction of adequate UPF commands from the high level abstraction semantics. The effectiveness of the proposed MDE approach is illustrated by an example.

Information System is one of the key domain in which lot of research has been done in the past few years. Applying Information systems to heterogeneous and distributed environments is one of the current research areas. Business Process Management Systems is the information systems which deal with the administration of tasks in the business processes, organizational structures, or in the related context. The Workflow Management system, the early idea of BPM, controls the workflow in an organization, data transfer, and integration of legacy information systems with existing programs and program modules, delegation of business tasks. Offering task management services especially modeling of business processes and underlying organizations, BPM serves it meaning and incorporates the WFM system. BPM supporting the use of knowledge concerning the awareness/unawareness of integrated software, and analysis of processes and organizational structure in terms of verification, modification, evaluation are key management in BPM system I.INTRODUCTION TO BPM: Combination of corporate restructuring and mergers urged the department and processes to be automated and linked together. Unfortunately it created largely disconnected spaghetti of systems and applications. Business Process Management (BPM) was born from a strong need to streamline internal processes and connections between both internal and external functions. It provides ability to model, monitor, manage and manipulate processes quickly in response to changes in strategy and market forces. BPM is an extension of classical Work Flow Management (WFM) systems and approaches. BPM delivers the maximum utility of legacy system. It is a method for revolutionizing the way the work moves throughout an organization. II.COMPONENTS OF BPM: The four key elements in Business Process Management are: Process modeling, Process rule, Process management, and Process performance analytics. Process modeling: Process modeling describes the flow of information (business process).It helps in building a model of process and mapping into an implementation frame work. Modeling requires a consistent analysis and representation of the processes. It forms the basis for the userspecific process environment. Process Rule: Process Rule is a heart of the BPM. It involves execution of discrete steps & integration of information. A process rules engine is used for this purpose. The engine is to monitor and manage the given steps by providing a flow control over the business process. If a process fails or delayed, a compensated action can be done to rectify. Process Management: Process Management is to correlate business/application events to fundamental business metrics .It enables the organization to monitor and optimize the business process. Once the process has been analyzed, modeled and the associated rules are formed. The next stage involves the visualization and management. Visualization means transaction data ranging from holistic to process-state or client state specific rules. Process Performance Analytics: Process Performance Analytics is a transition data source available for sophisticated management analytics .This data should be available on a retrospective or real-time basis. It should answer to one of the most difficult question like “how much does it cost to process a specific transaction?” By this way BPM mainly addresses four components. They are Work Flow Management, Content and records management Enterprise Application Integration (EAI) and Business Activity monitoring (BAM). III.RELEVENCE TO SYSTEM INTEGRATION: BPM can be fitted easily on the top of existing IT system. It is the Process rules that governs all the happenings and optimizes the process. BPM will not be able to work without the connectivity provided by the EAI layer. EAI layer provides BPM to gain and measure the value from the investment. On the other hand, BPM provides value to the EAI technology layer of Information technology. BPM layer offers business management the view of the message processing layer. It is used to unlock the value of the information held in the integration layer. It is also used to gather data of every transaction in the lifecycle. IV.APPLICATION OF BPM: BPM can be applied to any application which needs these advantages. BPM reduces unnecessary high losses in time critical transactions, helps to provide any critical information, practical application yield fast ROI ,better control over the information, identifying and maximizing the benefits faster, better analysis and tracking, provides enterprise-wide visibility of business processes, improve the effectiveness of the core operations, provides ability to coordinate interactions between information systems, business process and the people, flexible and easily changed by non-technical business people.

Organizations need to be agile and flexible to meet the continuous changes. Business Process Management (BPM) is harnessing the continuous changes suffered by organizations in the value chain and, therefore, in their processes. Simulation models offer the ability to experience different decisions and analyze their results in systems where the cost or risk of actual experimentation are prohibitive. BPMN models are not directly executable nor is it possible to simulate their behavior in various input parameters. This paper proposes the application of model-driven engineering (MDE) to integrate the definition of business processes with Discrete- Event Simulation (DES) as a tool to support decision-making. We propose a platform independent DES metamodel and a set of rules, to automatically generate the simulation model from BPMN 2.0 based business process in accordance with previous metamodel.

In the past decade, several approaches have been proposed for integrating security requirements into the model-driven engineering (MDE) of web applications. However, very little has been done to consolidate the knowledge about these approaches and analyze them from the perspective of common security threats, such as those listed in the Top 10 list of OWASP. This systematic literature review provides a state-of-the-art overview of the newly proposed approaches. It consolidates what is currently known about the level of their empirical evaluation and the extent to which each addresses the threats in the Top 10 list of OWASP. We examined 181 publications, of which 11 articles proposed new approaches to integrating security into the MDE of web applications. Our analysis of these 11 approaches reveals that most of them address the threat of Broken Access Control and that no approach exists that addresses all threats in the Top 10 list. Compared to a decade ago, we could see a clear trend towards using aspect-oriented methods to integrate security into MDE for web apps. Finally, we reflect on the implications of our results and the limitations of this work.

Nowadays, the problem in business process management (BPM) is that BPM systems should both be easy to use for business process developers and be based on a sound formal method. Business process management systems are often based on semiformal modeling techniques such as event-driven process chains (EPC) or UML. Unlike semiformal modeling techniques, the process calculus CSP comes with mature verification sup- port. Surprisingly little work has been done on using CSP for business process modeling and management. In this paper, we present our approach to business process management, which is based on the observation that CSP is well suited not only for specifying business processes and verifying work???ows but also for executing work???ows using our CSP4J framework. We report on a work???ow server, which is specified in CSP and implemented using our CSP4J framework. The server accepts work???ows that are modeled in CSP and also implemented using CSP4J. This allows us to integrate the mature verification support of CSP into both the management system itself and the development process of the end users’ business process definitions.

BRCode: An interpretive model-driven engineering approach for enterprise applications

Model-driven engineering has become the emerging standard for software development focusing on the use of models as first-class citizens. One possible field of application of such model-driven approaches can be the open source Content Management Systems (CMS) domain. Typically, CMS are built using the source-code-oriented software development process raising issues related to usability, performance and other qualities of service in an application’s lifecycle. To overcome these issues, the use of model-driven approaches in the development of CMS-based web applications (WAs) can be particular beneficial.To this end, we propose a model-driven reverse engineering approach for automatic mining of the conceptual model of existing WAs developed using the widely used CMS Joomla! by applying data mining techniques. This methodology can be used to form the cornerstone of an evaluation framework for Joomla!-based WAs either in the design or maintenance process.

In the modern business scenario, organizations are vesting high efforts in managing process sustainability as part of their operations management practices. The global environmental concerns for the welfare of the society have facilitated this change. Research studies have reported Information and Communication Technology (ICT) as one of the prerequisites in developing and maintaining efficient business processes. The process sustainability related initiatives and various processes related regulatory compliances have created the need for sophisticated IT tools like BPM (Business Process Management) and BI (Business Intelligence) in organizations. Thus with the advancement of ICT, a strong desire to enhance the business process performance through BPM and BI applications is felt across organizations. However, there is scant research available on leveraging the advantages of these applications in sustainability development. Therefore, this paper aims to present a conceptual architecture framework using an integrated BPM and BI solution to develop an orientation among practitioners and academicians towards the inclusion of ICT in attaining a sustainable, energy efficient business operations or processes. The framework is based on the literature pertaining to the role of BPM and BI in process sustainability as well as from the inputs of practitioners involved in the field of BPM and BI.
