Burbelo S. Technology Processing of Data of Information Systems With Variable Structure And Parameters

Object of research - the process of automated data processing information systems with variable structure and parameters (ISVSP); purpose is to improve the speed automated data processing ISVSP. Methods of research: Methods of the theory of relational databases (RDB) and models for formalization of operations on the data ISVSP, methods of systems analysis and mathematical modeling of automated processing of time-dependent data (TDD), methods, object-oriented programming to develop software components of information technology (IT). Theoretical results: the first time a method for forming an information model subsets of data based on a generalized model of a RDB, which, in contrast to the existing use of the proposed method for extracting the distribution criterion extractants that can modify the structure of the relationship between attitudes and contents of the selected tuples of data; first developed a method of planning processes in the information system based on TDD, priorities and constraints on the functional characteristics of the elements of the system to reschedule schedule tasks in the process of implementation, improved method of maintaining TDD in RDB with fixing all changes parameters, functions and interfaces and relationships between the data and their relationship, which differs from existing large volume storage options for all events information and changes at the same time reduces the amount of time necessary for automated processing and analysis of TDD for the first time a method for automated data processing ISVSP, which differs from existing information with new data management models that take into account changes over time parameters and algorithmic structures and automates the process of development of information system, aiming to extend the functionality and enables increase processing speed. Practical results - developed a new information technology data as a set of algorithms, RDB and software based on the developed models, methods and tools; algorithm, which generates and analyzes the phase space information system by changing the structure and parameters of TDD, which allowed increase the efficiency of data processing, the complex of carrying out structured description of relations and relational processing, systematize methods of handling, storage and analysis of data in ISVSP; developed software modules implementing IT for carrying out harvesting, searching, processing and transfer TDD and can speed automated data processing ISVSP. The degree of implementation - the main results introduced into OJSC "Vinnytsyaoblenergo" in the SEI in Vinnytsia region, as well in VNTU. Scope (branch) of use - information systems in different subject areas, as well as in the classroom.
