Requirements for Distributed Information Systems to Support Scientific and Educational Activities

Abstract

To increase the effectiveness of research, it is necessary to have access to systematic infor-mation resources of scientific work. Therefore, in any field of science, it begins with research, the search for scientific information, but with the growing number of scientific articles, books, mon-ographs, patents, the search for information becomes more and more difficult. Creating a unified information system that allows scientists to quickly get acquainted with the results of other scientific research and prevent their duplication. The main tasks of creating a model of a distributed infor-mation system that supports scientific and educational activities, the functional capabilities of the model, the concept of metadata, and the requirements for the metadata profile are described. The task, subject area, subjects, objects, the main functionality of the information system are de-fined, a list of the main types of information resources is provided. The paper analyzes the func-tional requirements for such systems. Purpose. In the process of creating distributed information systems that support scientific and educational activities, it is necessary to study the requirements imposed on the information system. Methods. The article discusses in detail technological methods for construc¬ting models of information systems for supporting scientific and educational activities. Results. Using the requirements, models, metadata of a distributed information system supporting scientific and educational activities, the architecture of the information system was developed and a scheme for exchanging information in the information system through information protocols was presented. Conclusion. The article discusses technological methods of a distributed information sys-tem that supports scientific and educational activities. The main tasks for building a model of a dis-tributed information system supporting scientific and educational activities, ensuring the functional functioning of the model, the concept of metadata for this system, and the requirements for the metadata profile are described. Based on the proposed requirements, the architecture of a distribut-ed information system supporting scientific and educational activities has been developed and the structure has been clearly described.

“…The paper [6] describes the main tasks of creating a model of a distributed information system, supporting scientific and educational activities, the functionality of the model, the concept of metadata, and the requirements for the metadata profile. The task, subject area, subjects, objects, the main functionality of the information system are defined, a list of the main types of information resources is given.…”

“…This technology will allow creating global infrastructures from dozens and hundreds of heterogeneous databases and solving strategic tasks in the field of automation of various forms of distributed activities. A narrower goal is to develop principles and software tools for virtual integration of distributed data sources based on international standards and recommendations for creating large-scale information infrastructures designed to virtualize data access to various DBMS using common rules and policies [6].…”
