In the paper one tried to present some semantic relations between hypotheticalable, theoretical, virtual worlds and real world. The objective of this paper is to prove that from the viewpoint of the semiontics decription language the possible world included some notions is not semantic empty set. Decription language is always pollute with real world meannings, which has already semantic arranged world.
The goal of the article is to present some aspects of supporting object-oriented approach to information systems development. There are discussed idea of CAME tools - computer aided method engineering tools, main diagramming techniques of object -oriented approach and problems of reuse components in a process of system development.

Considerations presented in the paper have been based upon the analysis of tendencies of computer science developement in management. On the basis of this there have been laid out the main directions of computer science application development in road traffic management in Poland.
The article deals with some problems concerning the possiblity of application of event's decree automatization in the frame of events accountancy, to improve the performance of Econoomical Information System (SIE - in short) in business. Especially, author stresses the influence of decree automatization on the integration and organisation processes of SIE. Sections 3 and 4 desribe some economical...
System Dynamics (SD) has been known as a technics of modelling and understanding the behaviour of complex systems for 40 years. In that time it has been interpreted from several different perspectives. This paper presents different views of SD, beginning from the classic one by Forrester, describes several weaknesses of SD and shows a current area of SD applications.
In this part of the paper four main problems are presented: 1.Identification of the virtual worlds with emphasis on world of our experience. 2.Accessibility relations of virtual worlds with emphasis on worlds postulated by scientific theories. 3.Assignment of the virtual world to known world or world of our experience. 4.The existence of the virtual world.
The paper decribes two different ways of communication between a database and the Internet. The first one leads through Common Gateway Interface scripts, interpreted by the web server. The provided example code is written in Pearl, and can be implemented in Unix or Windows NT. The second solution is Internet Database Connector, which allows to write interesting, but limited to the certain extent applications...
The goal of the article is to present importance of the information strategy of the enterprise. Goal, subject and scope of strategy are defined. Classification of environmetal objects is presented too.

There are discussed a number of posts - information professions - and there are given the main requirements refer to the work on these positions. There are also described desirable features of a computer...
Considerations presented in the paper have been based upon the analysis of the world tendencies of computer science development in management. On the basis of this there have been laid out the main directions of computer science application development in road traffic management in the world and in Poland. Passing to the most modern applications requires, first of all, developing applications on the...
The paper concentrates on the evolution of approaches to computerized information systems developpement. We can distinguish three approaches in 30 last years: functional, structural and object oriented. Each of approaches is examined. They are consequences of the developpement of information technology and information systems developpement methodologies.
