  • Recently, most of the information system use environment is changing to GUI environment based on windows and web. Most of the development tools for building such a GUI-based information system support object-oriented and event-driven programming concepts. However, there is still a lack of a development methodology that systematically supports event-based information system construction. From a business perspective, an information system is one that supports business processes efficiently and effectively to improve business performance. These business processes are composed of business activities which involve a series of business events. A business event is executed according to a business scenario. Therefore, it is necessary to grasp these events in the requirements analysis stage and to apply it on the system development methodology. However, information systems development methodology which systematically reflect the event processing concept still is insufficient. From this viewpoint, this paper proposes an event-driven scenario-based development methodology that can meet the recent development environment of information systems, and applies the proposed methodology to a small scale information system development case.

  • This paper presents a structured framework for developing the embedded subsystem, called ESDMP (Embedded Subsystem Development Methodology for POP), which is one of core components at the development of POP (Point Of Production) system. It is essential that embedded subsystem development methodology must be closely related to the general information system development methodology from the early stage of system development. Therefore, this paper investigates the PDSM (Production System Development Methodology) that is developed by Korea Technology and Information Promotion Agency for SMEs and widely utilized at the fields of POP system development, and proposes the embedded subsystem development methodology aligned with each step of PSDM. The main characteristics of proposed methodology are as follows : First, it is developed to link each step of embedded subsystem development with relating steps of PSDM from the early stage of feasibility study. Second, it provides the procedure for designing and implementing hardware and software simultaneously. Third, it includes the method of reusability for developed products and modules.

  • A methodology is often used in solving complex problems. As a typical case of complex problem solving, development of information systems mostly requires a use of system development methodology. However, it is not always easy or smooth for organizations to adopt the methodology and to achieve a positive outcome from their application in real project situations. Although there are a few studies to find out success factors in the implementation of the methodology, they did not take into consideration essential characteristics of the methodology. This study aims to analyze the quality of the methodology as a key determinant to influence the performance of the methodology application.

  • Recently, many enterprises have attempted to construct data warehousing systems for decision-support. Data warehouse is an intelligent store of data that can aggregate vast amounts of information. Building DW requires two important development issues:(i) DW for the decision making of business users and (ii) metadata within it. Most DW development methodologies have not considered metadata development; it is necessary to adopt a DW development methodology which develops a DW and its metadata simultaneously. Metadata is a key to success of data warehousing system and is critical for implementing DW. That is, metadata is crucial documentation for a data warehousing system where users should be empowered to meet their own information needs; users need to know what data exists, what it represents, where it is located, and how to access it. Furthermore, metadata is used for extracting data and managing DW. However, metadata has failed because its management has been segregated from the DW development process. Metadata must be integrated with data warehousing systems. Without metadata, the decision support of DW is under the control of technical users. Therefore, integrating data warehouse with its metadata offers a new opportunity to create a more adaptive information system. Therefore, this paper proposes a DW development methodology from a metadata perspective. The proposed methodology consists of five phases: preparatory, requirement analysis, data warehouse (informational database) development, metastore development, and maintenance. To demonstrate the practical usefulness of the methodology, one case is illustrated

  • The land informatization methodology is the system development methodology that can be applied to the land information system to construct, manage and use the land information. Therefore, understanding of development methodology of information system and special conditions regarding the land informatization is very important. In order to enhance the understanding of land informatization, we tried various analyses on the previous land information systems developed in KOREA(PBLIS, LMIS, KLIS, KRAS) first. Then, we make a basic system development methodology to fit the land information reference model based on EA(Enterprise Architecture) and components based system. In addition, we investigate various problems or issues that occurred during the process of 30years' experience in KOREA land informatization. At last, we construct the detailed land informatization methodology which was added the method how to tasks to be carried out in each stage to solve those issues. It is the unique land informatization methodology having the most of the distinct characteristics of land information.

  • The history of information system (IS) development methodology in Korea is less than 30 years. Korea introduced the structured development methodology in the public fields in 1980s, introduced the information engineering methodology in 1990s, and accepted and developed the objected oriented development methodology and the component based development methodology in 2000s. The history of IS development methodology in Korea is shorter than that of the world. Korea's IS development methodology started 10 year later compared with the world level. But it developed rapidly in 1990s and then grew to the world level in 2000s. This paper is the first research that it investigated the history of IS development methodology in Korea. This paper will give the people of IT industry the historical insights about IS development methodology and will help make a current and future strategic plan for IS development methodology. And it will provide researchers and policy makers with the insights and research ideas of future direction of information system development.

  • Digital Humanities System is a method to effectively share and spread Humanities information and knowledge to users by using information technology. It Also comes into the spotlight as a new research methodology for researches of Humanities researchers. Digital Humanities System distinguishes itself from other existing information systems. Therefore, when the system is developed, it needs to supply with manpower related to development process which is specialized for Digital Humanities System, not for the several established construction methodology. Digital Humanities System studies recently is mostly constructed using the usual methodology of information system construction. Because of its falling efficiency and usability after constructing the system, however, examples of failure of operating system occur. In this paper, accordingly, effective and creative Digital Humanities System development methodology will be studied from the point of view of information technology through collaboration with various field of expertise. In detail, based on information system methodologies in software engineering perspective, we propose a methodology to build a specialized system in the digital humanities.

  • Information competitiveness accounts for substantial parts of business competitiveness necessary for business management in the knowledge-information society in the 21st century. To improve quality. productivity and competitiveness through information in the fields of SMEs particularly having difficulties under rapidly changing business environment. the government has operated "SME Information Support Project" for the past 8 years. The methodology for developing the standard for this project known as EISDM (Enterprise Information System Development Methodology) provides communication between IT businesses and SMEs participating in this project. and standardized output document formats and how to make out such documents. Infortunately. the number of personnel partaking in the development project for SMEs is no more than 2~4 per site on average. Further. they are required to complete demand analyses. development. testing and operation in about 6 months. which is a very short period. Moreover, there is too much demand for documentation, which is likely to end up being formal work process just for supervision and inspection. That is, the documentation could be for noting but documents. which will prove useless outputs after the project finishes. Therefore, this study proposes an improvement approach as an information system development methodology taking into account SMEs' characteristics and environment so as to relieve developers from such excessive burden of documentation, to save time and resources through efficient management of software development as the original purpose of the methodology, and to produce required quality software.

  • This paper presents an efficient methodology for information system development by adopting the concept of extended components which can achieve the improvement of development productivity, reductrion of development time periods, quality improvement of information systems, etc. when information development projects are carried out. First of all, for efficient development of information systems, development steps of current methodologies for information system analysis are subdivided into components in detail and outputs required at each step are defined. The components are extended by types and various application methods are proposed in each step of information system development. In addition, a method which uses advantages of current methods such as SDLC, prototyping, and RAD, is also proposed. In this research, a CASE tool named S-Designer is used for the development of extended components and their interface, and a system development method called DSDM for the deviation of detailed steps and corresponding outputs.
