INFORMATION SYSTEM DEVELOPMENT METHODOLOGY: RESOURCE MODEL DESIGN

Metodika projektiranja informacijskih sustava usmjerena je na oblikovanje modela procesa, modela podataka i modela resursa kroz četiri faze razvitka: planiranje, analizu, oblikovanje i konstrukciju. Suvremeni CASE alati sadrže komponente za modeliranje procesa i podataka ali ne i resursa. ulazak otvorenih sustava i Korisnik/Poslužitelj obrade podataka povećava samostalnost i nezavisnost investitora ali, i odgovornost projektanata. Stoga se u radu predlaže metoda za oblikovanje modela resursa te odrednice za arhitekture i standardne zahtjeve za resurse pri orijentaciji na otvorene sustave.The objective of information system development methodologies is design of three models: process model, data model and resource model during the stage of planning, analysis, designand construction. CASE too/s contain components for process and data model design but there is no component for resource model design. Implementation of open system architecture and client/server data processing technology results with: (1) higher indenpendency of investitors, and (2) higher responsibility of designers. Procedure for resource model design and recommendation and resource requirements for "open system" implementation is proposed in this article

A methodology for the design and evaluation of user interfaces for interactive information systems

The definition of proposed research addressing the development and validation of a methodology for the design and evaluation of user interfaces for interactive information systems is given. The major objectives of this research are: the development of a comprehensive, objective, and generalizable methodology for the design and evaluation of user interfaces for information systems; the development of equations and/or analytical models to characterize user behavior and the performance of a designed interface; the design of a prototype system for the development and administration of user interfaces; and the design and use of controlled experiments to support the research and test/validate the proposed methodology. The proposed design methodology views the user interface as a virtual machine composed of three layers: an interactive layer, a dialogue manager layer, and an application interface layer. A command language model of user system interactions is presented because of its inherent simplicity and structured approach based on interaction events. All interaction events have a common structure based on common generic elements necessary for a successful dialogue. It is shown that, using this model, various types of interfaces could be designed and implemented to accommodate various categories of users. The implementation methodology is discussed in terms of how to store and organize the information

Object-oriented modelling with unified modelling language 2.0 for simple software application based on agile methodology

Unified modelling language (UML) 2.0 introduced in 2002 has been developing and influencing object-oriented software engineering and has become a standard and reference for information system analysis and design modelling. There are many concepts and theories to model the information system or software application with UML 2.0, which can make ambiguities and inconsistencies for a novice to learn to how to model the system with UML especially with UML 2.0. This article will discuss how to model the simple software application by using some of the diagrams of UML 2.0 and not by using the whole diagrams as suggested by agile methodology. Agile methodology is considered as convenient for novices because it can deliver the information technology environment to the end-user quickly and adaptively with minimal documentation. It also has the ability to deliver best performance software application according to the customer's needs. Agile methodology will make simple model with simple documentation, simple team and simple tools.Comment: 15 pages, 30 figure

User-centred interface design for cross-language information retrieval

This paper reports on the user-centered design methodology and techniques used for the elicitation of user requirements and how these requirements informed the first phase of the user interface design for a Cross-Language Information Retrieval System. We describe a set of factors involved in analysis of the data collected and, finally discuss the implications for user interface design based on the findings

Orthogonal-Array based Design Methodology for Complex, Coupled Space Systems

The process of designing a complex system, formed by many elements and sub-elements interacting between each other, is usually completed at a system level and in the preliminary phases in two major steps: design-space exploration and optimization. In a classical approach, especially in a company environment, the two steps are usually performed together, by experts of the field inferring on major phenomena, making assumptions and doing some trial-and-error runs on the available mathematical models. To support designers and decision makers during the design phases of this kind of complex systems, and to enable early discovery of emergent behaviours arising from interactions between the various elements being designed, the authors implemented a parametric methodology for the design-space exploration and optimization. The parametric technique is based on the utilization of a particular type of matrix design of experiments, the orthogonal arrays. Through successive design iterations with orthogonal arrays, the optimal solution is reached with a reduced effort if compared to more computationally-intense techniques, providing sensitivity and robustness information. The paper describes the design methodology in detail providing an application example that is the design of a human mission to support a lunar base

Perancangan E-Board sebagai Alat Distribusi Informasi pada Sistem Kerja Sama Asinkron Tersebar

The design of e-Board was undertaken to meet the necessary of information between colleagues that nowadays has become more essential and vital especially in a team work that applying distributed asynchronous co-operative work system. In which, members of the team are distributed in time and space; therefore information should be well distributed to support the cooperative work between them. The research was applying analysis and design methodology. The analysis methodology was undertaken through literature study, current system observation, questionnaire survey to users to identify characteristics of the current and entailed information distribution media. The design methodology was undertaken through database, features, system, and screen layout design. Results of the research found that the information distribution media for team work which has applied distributed asynchronous co-operative work system should have the ability of private access for each member, better organization in information categorizing, structured information for task assignment, and supporting member's mobility. In conclusion, the application has been expected to help task assignment, distribution and organization of information in the distributed asynchronous co-operative work system to be easier and simpler

Preliminary Design of Reactive Distillation Columns

A procedure that combines feasibility analysis, synthesis and design of reactive distillation columns is introduced. The main interest of this methodology lies on a progressive introduction of the process complexity. From minimal information concerning the physicochemical properties of the system, three steps lead to the design of the unit and the specification of its operating conditions. Most of the methodology exploits and enriches approaches found in the literature. Each step is described and our contribution is underlined. Its application is currently limited to equilibrium reactive systems where degree of freedom is equal to 2 or less than 2. This methodology which provides a reliable initialization point for the optimization of the process has been applied with success to different synthesis. The production of methyl-tert-butyl-ether (MTBE) and methyl acetate are presented as examples
