Using Fuzzy Logic to Evaluate Normalization Completeness for an Improved Database Design

Abstract: A new approach, to measure normalization completeness for conceptual model, is introduced using quantitative fuzzy functionality in this paper. We measure the normalization completeness of the conceptual model in two steps. In the first step, different normalization techniques are analyzed up to Boyce Codd Normal Form (BCNF) to find the current normal form of the relation. In the second step, fuzzy membership values are used to scale the normal form between 0 and 1. Case studies to explain schema transformatio… Show more

“…A fuzzy-based modelling of emotions enables the identification of linguistic patterns that intensify or reduce such emotions. Fuzzy logic is also used for evaluating the normalization completeness [34]. It was carried out in two steps -finding the relation's normal form and scaling the normalization.…”

“…In order to illustrate uncertainty and vagueness mathematically, fuzzy concept is specifically designed. Everything is a matter of degree in fuzzy logic and knowledge is interpreted as a collection of elastic or equally fuzzy constraint on a collection of variables [32][33][34][35][36][37][38]. Concept of Linguistic variable plays an important role in fuzzy logic and their values are words or sentences in natural language [39,40].…”

“…Literature shows that there is several approach have been used to minimize the data redundancy, such as converting an ERD scheme according to steps of an algorithm for ER-to-relational mapping, and applying the normalization rules [15] [17]. In relational database design, normalization is the process of organizing data to minimize redundancy [3].…”
