A multitude of heterogeneous data must be converted to environmental-conscious information and kept ready by Corporate Environmental Management Information Systems (CEMIS) to support environmental protection, sustainability, and energy efficiency within companies. Since these systems are currently not applying strategic information and decision support, contemporary systems do not cope with requirements from the sustainability discussion. Early identification of cause-and-effect-relationships is vitally important to be able to anticipate environmental impacts of decisions and, thus, to intervene in time. Otherwise the potential for acting precautious would remain unemployed. A resource-friendly design of business processes and their energyand material-efficient control additionally demands for sustainability-oriented organizational structures as well as incentives for all stakeholders involved. The authors strive for developing a new generation of CEMIS that copes with strategic sustainability aspects. They present the results from a survey that prioritizes the requirements the authors have gained from former inquiries, workshops and expert interviews. As a direct result of the survey, first implications for architectural concepts are presented.

Traditional EA concepts in the Enterprise Application Integration (EAI) domain focus on ex-post integration of application interfaces by pipelining different middleware technologies like message queuing or remote method invocations [1, 2]. Web Service enabled Service-Oriented Architectures (SOAs) used in the EAI context were a step towards providing an abstraction layer for the involved interfaces by using the Web Service Description Language (WSDL). The idea of SOA enlarges by applying Semantic Web Services (SWS) technology to it. OWL-S and WSMO are two examples for concrete implementation approaches in this area [3, 4], and we will demonstrate semantic WSMO framework, and how it can solve the problems of traditional SOA.

Nowadays, it is getting more and more difficult discovering the entire Web resources in order to find the correct information needed by user. The correctness of the retrieved results in most cases is not meeting the expected needs because of the weak definition requests provided by the user and this came from the unstructured nature of the existing information resources.

Model-driven software development proposes model transformations as a key system design principle. However, devel-opment of model transformations can be considered as a complex task because of the semantic difference in involved models. In par-ticular, we are interested in the improvement of transformations between organizational and functional requirements models be-cause the current best approaches support only forward and semi-automatic derivation of the later from the former and do not ad-dress different workflow patterns, lack of traceability and tool support, besides not taking advantage of incremental and bidirec-tional approaches. Model synchronization techniques are pro-posed to address these challenges. In this paper, we present an analysis of the main model synchronization engines reported in the literature as well as their tool-support based on a defined set of problem-specific requirements. We present also an approach to achieve these requirements by defining a general mapping scheme and model synchronization rules to be used in the context of soft-ware development process. Initial results and further research steps on it are finally reported.

The most academic institutions in Arabic countries depend on the centralized or decentralized information systems, operating independently from each other, the decision-makers rely on these systems in generation of the periodic and routine reports, that assist them in building the right decisions and proper responses to the changes in a timely manner.

Business intelligence has been widely integrated in enterprises to help their employees in their decision making process by delivering the needed information at the right time. Statistics from Gartner Group showed that the investment in the business intelligence domain has recently been very high. However, different studies and market researches showed that the pervasiveness and the usage percentage rate of business intelligence are still very low. The reason behind that is the complexity of the usage of business intelligence systems. Moreover, enterprise users lack analytical skills. To mitigate this problem, a new concept of self-service business intelligence has been developed. Within this system, the knowhow of power user is extracted and delivered to business users in form of recommendations. In this paper, we present the conception and development of the tracing module of this new system. This module has the goal of tracing the interactions of power users as the first step to extract their procedural knowledge in form of analysis paths. This is done by creating a user interaction catalogue in which the interactions are defined based on their relevance to the knowledge extraction process. Finally, this paper presents the internal architecture of this tracing module and its components.

This article presents a detailed implementation of the Corporate Environmental Management Information Systems CEMIS Next Generation platform of the IT-for-Green research project. The provided services within this platform are grouped based on the module to which they belong. These services will be the main realization of the workflows activities of the systems business processes. In the frame of this project, the Next Generation CEMIS will be developed, to integrate research concepts of current interest and investigate their feasibility through a prototypical implementation. In this paper the authors focus on two major components: the workflow engine implemented using State Chart XML SCXML and the Green Service Mall realized as a set of standardized Web Services.

The proposed OEPI platform and its accompanying services are implemented specific to the industrial partners of the OEPI consortium and cannot be adapted by other companies without engineering the whole OEPI platform. Especially SMEs cannot afford the development efforts needed to implement OEPI’s reference model in their own infrastructure. In this chapter a proposed solution using a more generic architecture that will be applied to the specific area of environmental performance indicators will be presented. It is an ontological SOA-based solution that deals with semantic-annotated Web Services. The main outcomes that can be harvested from using this solution in the environmental field are: the high reusability of its components where each component can be seen as a standalone system, the utilization of Web Service-based workflows that takes benefit from the market best practices, the design of an applied ontology model for Web Services and finally Web Service validation and ranking. Moreover, One of the main purposes of this architecture is to group the Web Services based on their actual domain to which they are related (the area of interest). This solution will be applied as an example to the difficult task of handling diverse environmental data sources in the OEPI project.

In this chapter authors present the Web Service-enabled CCEMIS solution that is mainly relying on the idea of supplying Web Services from different CEMISs to handle corporate environmental issues. This solution reduces the efforts to achieve a legal compliance environmental management. It proposes an environmental collaboration between companies via summing up all the required information from different involved players in form of Web Services. In this solution, the companies will act as consumers and providers at the same time. They are both requesting and supplying environmental data. They maintain their identities by not revealing the information regarding their resource details.
