Database Normalization Debt: A Debt-Aware Approach to Reason about Normalization Decisions in Database Design
Technical debt is a metaphor that describes the long-term effects of shortcuts taken in software development activities to achieve near-term goals. In this study, we explore a new context of technical debt that relates to database normalization design decisions. We posit that ill-normalized databases can have longterm ramifications on data quality and maintainability costs over time, just like ...
متن کاملFormulas of Retrieval Rate in Database Based on Normalization Design
A normalization database is considered as mathematics logical design to avoid redundancies and inconsistencies in the stored data which brought about null data and many relationship tables in the physical database. A retrieval rate is affected directly in running a practical system of the normalization design. We argue in the paper that rate formulas given out retrieval speed via testing the va...
متن کاملBiological Database Normalization by Sequence Alignment
The Michigan Molecular Interactions (MiMI) database contains protein interaction data from many distinct sources. Frequently, the same protein is referred to in different external databases by different identifiers, so it is difficult to determine when different records refer to the same object. The normalization problem is addressed by creating an extended MiMI database that integrates MiMI wi...
متن کاملJustifying Database Normalization: A Cost/Benefit Model
During the information systems development process within an organization, data resource is typically analyzed in the form of a data model. During this data analysis phase, the data model is further refined so that it obeys certain rules of good behavior. Normalization is the process of grouping data into such well refined structures. Determining an appropriate normal form has not been clear to...
متن کاملUsing Fuzzy Logic to Evaluate Normalization Completeness for An Improved Database Design
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, f...
