Data Base Concepts for Systems Analysis
نویسنده
چکیده
Systems analysis is the examxna.t on of a problem situation in order to define the requirements of a solution, often computerized, to that problem. The diversity of prob ems and the constraints of computing technology require that a probWra be thoroughly analyzed in order to insure that the problem is claarly understood. Then, and only then, it can be determined how ccuputing technology can be applied to solve the identified prob)am. A particular difficulty during systems analy is is determination < f the cont 'nts of the data base and design of the logical structure of that data base. Several recent developments offer new perspectives for systems analysis and data base design. These developments provide a conceptual framework for understanding informati >n system and data base characteristics. This framework supports an improved methodology for systems analysis.

متن کاملPOTENTIAL ENERGY BASED STABILITY ANALYSIS OF FUZZY LINGUISTIC SYSTEMS
This paper presents the basic concepts of stability in fuzzy linguistic models. Theauthors have proposed a criterion for BIBO stability analysis of fuzzy linguistic modelsassociated to linear time invariant systems [25]-[28]. This paper presents the basic concepts ofstability in the general nonlinear and linear systems. This stability analysis method is verifiedusing a benchmark system analysis.

Problem of knowledge analysis for decision support system is the most difficult task of information systems. This paper presents a new approach based on notions of mathematical theory of Rough Sets to solve this problem. Using these concepts a systematic approach has been developed to reduce the size of decision database and extract reduced rules set from vague and uncertain data. The method ha...
متن کاملObject-oriented Data Bases
INTRODUCTION Object-oriented (OO) programming languages and OO analysis and design techniques influence data base systems design and development. The inevitable result is the object-oriented data base management system (OODBMS). Many of the established data base vendors are incorporating objectoriented concepts into their products in an effort to facilitate data base design and development in t...
متن کاملStability analysis of nonlinear hybrid delayed systems described by impulsive fuzzy differential equations
In this paper we introduce some stability criteria of nonlinear hybrid systems with time delay described by impulsive hybrid fuzzy system of differential equations. Firstly, a comparison principle for fuzzy differential system based on a notion of upper quasi-monotone nondecreasing is presented. Here, for stability analysis of fuzzy dynamical systems, vector Lyapunov-like functions are defined....
