ANALYSIS OF THE PROPOSED SEMANTIC APPROACH TO DESIGN OF INFORMATION SYSTEM INTERFACE

Abstract

The development of software (information systems in particular) is a time-consuming process. As statistical research shows more than half of the projects on the creation of information systems are not successful (there are some difficulties, or not implemented at all). All existing approaches consider the development of the system from the point of view of the objective concept, which represents the system as "a set of elements and relations between them." This leads to the problem of transition between the stages of the development of IS and in particular the transition between the stages of designing the IP. The problem is the transition between sets of elements of different levels (for example, elements of the domain and elements of the system) and, respectively, between the relations between them, and as a rule this transition is made empirically by the developers of the IS. The article proposes the solution of this problem and a new look at the design of information systems in general. The proposed approach is aimed at formalizing the process of designing the properties and functions of the system and removing the empirical component that presents in IS design today. For this, it is proposed to consider the methods and techniques used in the development stages of information systems. At the same time, each stage of the information systems development has its own methods. A model is proposed for describing the methods used at different stages in the development of information systems. This model includes such concepts as method, methodology and norm (a set of concrete actions). The paper describes the process of reconciling these concepts, consisting of two levels: vertical and horizontal alignment. Based on the proposed principles and design method, the CASE-tool is proposed. The proposed model will form the basis of the developed CASE-tool that allows, based on the description of the methods of different stages, to obtain a consistent model, without an empirical component.
