MDM

MDM is a tool that enables the users to define schemes of different data models and to perform translations of schemes from one model to another. These functionalities can be at the basis of a customizable and integrated CASE environment supporting the analysis and design of information systems. MDM has two main components: the Model Manager and the Schema Manager. The Model Manager supports a specialized user, the model engineer, in the definition of a variety of models, on the basis of a limited set of metaconstructs covering almost all known conceptual models. The Schema Manager allows designers to create and modify schemes over the defined models, and to generate at each time a translation of a scheme into any of the data models currently available. Translations between models are automatically derived, at definition time, by combining a predefined set of elementary transformations, which implement the standard translations between simple combinations of constructs.

This thesis presents a new modelling method for information systems analysis and design, where the concept of service and the principles of service orientation are used for integrated modelling and reasoning about information systems architectures across organisational and technical systems boundaries. The concept of service enables cohesion of the intersubjective and objective modelling traditions by using a single type of diagram that facilitates detection of semantic inconsistency, incompleteness, ambiguity and discontinuity between the static and dynamic aspects of information systems specifications. The thesis is focused on three research topics, which are fundamental to the development of a new service-oriented modelling method. The first research topic concerns a pragmatic-driven specification of information systems. It clarifies answers to the research question: How can a conceptual modelling process be driven by pragmatic considerations? The second research topic provides a service-oriented modelling foundation for information systems analysis and design. It answers the research questions: How can the concept of service be used explicitly for the analysis and design of information systems and how can the static and dynamic aspects of information systems specifications be integrated at the conceptual level? The third research topic presents transition principles to implementation-specific design and answers the research question: How can service-oriented conceptual representations be aligned with implementation-specific design? The thesis contributes with a new knowledge to the area of conceptual modelling of information systems. The service-oriented modelling method consists of the modelling process, modelling language and techniques for the analysis and design of information systems on three levels of abstraction: pragmatic, semantic and syntactic. These three levels are necessary for a holistic understanding of enterprise architecture by stakeholders. The advantage of the service-oriented modelling method is that it can help to control traceability from information system design to original requirements. The method facilitates the semantic integration of the structural, behavioural and interactive aspects of information systems conceptual representations by using a single diagram type. The modelling language provides service-oriented constructs that are fundamental to building the major systems analysis patterns. The service-oriented modelling process contributes with seven steps of incremental design, which justifies various information systems components. The method provides the basis for a gradual and systematic way of modelling and an understanding of how pragmatic, semantic and logical information system requirements are linked together. The possibility to detect and eliminate undesirable characteristics of service-oriented diagrams can help to improve communication among stakeholders. Service-oriented specifications are computation-neutral and therefore they are more comprehensible for business analysis experts in comparison to implementation specific graphical representations of information systems. Finally, this thesis presents the challenges for future research, one of which is the development of the automated tools for the alignment of business models with implementation-specific information systems specifications.

This research examines the definitions and interpretations of mindfulness in information systems (IS) literature and in Buddhism. It extends a previous qualitative case study (Wang, 2015) and further examines the students’ learning outcome in mindfulness and their interpretations of mindfulness in information systems development and end user experience. Students in a Systems Analysis and Design undergraduate course were asked to design websites for a contemplative community of practice. More than half of the IS students can interpret mindfulness using both the concepts in the existing IS literature and in Buddhism, even without the explicit exposure to the literature. For those students who have not related to both, they applied the IS literature to interpret mindfulness in systems development and applied Buddhism to interpret mindfulness in end user experience. Overall, the majority of the IS students who were exposed to mindfulness have recognized its importance in IS design and in end user experience and learned to express themselves with the terminologies of mindfulness, awareness, and contemplation.

Organizational engineering addresses various aspects of changing organizations in order to create and keep the alignment between business and information technology (IT). In this paper, we show how the combination of cybernetic theories with conceptual modeling contributes to the analysis and design of information systems and organizations. Based on the discussion of a language-driven understanding of information systems as socio-technical systems, we show how conceptual models can significantly contribute to organizational engineering if used in combination with the concept of variety, an established theory from cybernetics. Within an IT controlling case, we show how our approach can be applied to the diagnosis of an IT controlling and reporting system in the German subsidiary of a large European bank.

The system analysis is the necessary activity in designing information systems (IS), especially in creating complex IS which have to satisfy a wide pallet of users’ demands. Installing the IS without expert’s planning and leading can lead to the huge users’ dissatisfaction, and maybe non - usage of system which often the consequent system do not work. This is especially emphasized when we talk about web based IS which demand a strong defined access rules as well as accurate data update procedures. In this paper is made a system analysis and design of IS for local economic development (LED). The problem of LED itself is very important because of the decentralization process that happens in R.of Macedonia in recent year as well as the global crises and the necessity of employment increasing. As an important factor we mention a need of increasing the usage of IS, especially when is concern of the issues that help for the young people’s position. Analysis of the need of IS for LED’s support is made on the couple of present local governments’ (LG) web sites in R.of Macedonia as well as the interviews and a questionnaire of the LER’s responsible in the LG and potential users of this kind of information. The results of this survey are decanting in analysis of the information needs as well as the LED’s support System’s proposition. We are using the structural analysis and logical design of IS as the working’ methodology. For this purpose, a series of systematic undertaken processes were used. These processes, we think, that will enhance the information and usage of computer’s IS in function of business climate and business community’s better information. The proposed model for LED’s support IS which have to cover the users’ demands will be made with creating a redundant databases, loaded whit trigger procedures and intelligent agents.

Theoretical development in the area of databases systems has been keeping its dynamics. One of its directions is unfolding the conception of derived data. Models based on derived data are the outcome of the combination of logic programs and databases. They can potentially solve many problems in analysis, design and implementation of databases and information systems and add semantics to the databases. We can use deductive rules for derivation of classes/relations, derivation of attributes, views, for design of query, for expressing integrity constraints.

Although many information systems (IS) design methods and techniques are available to IS professionals, none of them completely supports the design process. One of the problems is that there is a mismatch between IS design method; and the system to be built. Actually, in designing an IS, the methods or techniques employed should match the types and characteristics of the system to be built. Thus paper will explore the relationship between IS types/characteristics and systems design methods, and provide IS designers with a systems framework to develop methods or techniques that match the types and characteristics of IS.

This paper advances the long term project of developing a situated information systems analysis and design methodology. Conventional approaches to information systems design are informed by the widely-held view that human purposeful action proceeds by deliberation on a mental model of the world of action. In contrast, situated information systems are informed by the view of situated action theory that routine action is largely non-deliberative and makes crucial use of structures in the action environment for attainment of goals. The expectation is that systems designed using this situated approach will be more effective in supporting routine activity than systems designed using the conventional approach. This paper reports on a case study conducted in the chemotherapy unit of a large hospital. The case study was conducted using the preexisting version of the situated systems methodology with the results of the case study informing further development of the methodology. The research provides further evidence of the ability of information systems informed by a situated model of action to effectively support complex but largely routine activity.

This article explores the potentials of systems analysis and design of information system for sustainable natural resource management. Soft and hard system analyses were performed to better understand the information needs and design of an information system for improving decision making for achieving sustainable natural resource management. In order to analyze the complex and soft systems situations for developing an effective information system, which meets related actors’ changing needs, a conceptual model inspired by soft systems methodology (SSM) was developed. This model is based on information derived from twelve farmers who were purposely selected to represent diverse conditions and 23 agricultural extension experts across the Alborz Watershed in Mazandaran Province, located in northern Iran. Since a conceptual model resulting from SSM is not in itself sufficient as the basis for the implementation of information systems, a hard system methodology was used to structure the data handling by using unified modeling language. This research has shown the promising potentiality of using soft system analysis methodology as a preliminary step to the actual design of an information system in the natural resource management situation in the watershed system level when combined with hard system analysis methods.

This paper presents our own approach to modeling, visualization and simulation of biology-related processes. It presents the own BORM (Business and Object Relation Modeling) approach, which is an application of the object-oriented paradigm and finite-state machines. The first part of this paper discusses the motivation for the new approach and explains its theoretical foundation. The second part presents our practical experience with BORM as the method enabling necessary capture of requirement and verification activities for the analysis and design of information systems. The real example of the largest Prague Hospital is used. The BORM method has been used in the last 17 years on various projects in the Czech Republic and Central-European region.

Analyzing information systems development: A comparison and analysis of eight is development approaches

This paper describes the use of computer-aided analysis for the design and development of an integrated financial management system by the Navy Material Command Support Activity (NMCSA). Computer-aided analysis consists of a set of procedures and computer programs specifically designed to aid in the process of applications software design, computer selection and performance evaluation. There are four major components: Problem Statement Language, Problem Statement Analyzer, Generator of Alternative Designs, and Performance Evaluator. The statement of requirements was written in ADS (Accurately Defined Systems) and analyzed by a Problem Statement Analyzer for ADS. The ADS problem definition was supplemented with additional information in order to create a complete problem definition. The analyzed problem statement was translated to the form necessary for use by the SODA (Systems Optimization and Design Algorithm) program for the generation of alternative specifications of program modules and logical database structures.

Business process (BP) models are presented as a major key in the design and analysis of information systems and are considered as a good mechanism for communication among the stakeholders. Therefore, it should be founded on excellence methodologies and directed by a reliable quality approach. That is why, it is important to define the quality of BP models, which should be determined the application of a set of criteria. In this paper, we look for identify a set of typical and consistent criteria considered as substantial, for BP models by focusing on the needs of stakeholders with the aim of achieving good quality. These requirements are established by first passing through a preliminary study that is based on a questionnaire designed in order to assess the importance attributed to the mentioned criteria. The responses given to this questionnaire will be analyzed with an algorithm of classification for data mining in order to identify the quality criteria from the expert’s point of view, given their relative importance.

1.0 - Introduction

In this paper, we continue our long-term project of developing a situated information systems analysis and design methodology, and present it as a radical alternative to conventional information systems analysis and design. Taking a situated approach entails focusing on action and a situated analysis and design methodology aims to increase efficiency and effectiveness through supporting routine action. We suggest that, as well as improving effectiveness and temporal efficiency, applying the situated methodology will result in less wasted human effort expended in search of information. We discuss the implications of an action focus for our conception of what an information system should be, and illustrate the application of the methodology with examples from a case study.
