Why Normalization Failed to Become the Ultimate Guide for Database Designers?

Marin Fotache
2006 Social Science Research Network  
Almost every database textbook treats normalization in a certain extent, usually suggesting that the topic is so clear and consolidated that it does not deserve deeper discussions.  ...  It outlines the main weaknesses of normalization and offers some explanations about the failure of a generous framework in becoming the so much needed universal guide for database designers.  ...  It also seems that normalization topics have become too obsolete for the scientific community. Besides a number of articles trying to establish the normalization principles for XML databases (!)  ...

Shadow Theory, data model design for data integration [article]

Jason T. Liu
2012 arXiv   pre-print
It is based on the notion of shadows in Plato's Allegory of the Cave.  ...  What we can observe are just shadows, and meanings of shadows are mental entities that only exist in viewers' cognitive structures.  ...  In next section, we will include this topic in our answers for the next question about for how to help users understand the data and what happened in databases.  ...

Exploring the Scientific Impact of Information Systems Design Science Research

Gerit Wagner, HEC Montréal, Canada & Regensburg University, Germany, ulian Prester, Guido Schryen, UNSW Sydney, Australia, Paderborn University, Germany
2021 Communications of the Association for Information Systems  
In this study, we focus on active, IS-specific DSR areas and consider papers published in the AIS Senior Scholars' basket of journals between 2004 and 2014.  ...  While design science research has established its position as a prominent field of research in the IS community, there is a lack of transparency regarding the impact of recent information systems design  ...  We also thank Richard Schuster and Philip Empl for their comments and support.  ...

Authorization in trust management

Peter C. Chapin, Christian Skalka, X. Sean Wang
2008 ACM Computing Surveys  
In this paper we survey modern stateof-the-art in trust management authorization, focusing on features of policy and rights languages that provide the necessary expressiveness for modern practice.  ...  By allowing providers to specify policy, and access requesters to possess certain access rights, trust management automates the process of determining whether access should be allowed on the basis of policy  ...  The semantics of PolicyMaker is graph theoretic. Each assertion is represented as a labeled edge in directed graph G where the vertexes of G are public keys or POLICY.  ...
