TLDR
The normalized approach to data base design provides for data bases that satisfy user needs and establish a logical design done only once regardless of the DBMS or computer system that will subsequently use the data.Abstract:
Today's users want to access their data through fourth-generation languages, or 4GLs, and microcomputers. More flexible data bases are required to satisfy this growing need. These data bases must be based on the data as perceived by users, not as viewed by a system—the normalized approach to data base design provides for this. Data bases can be built that satisfy user needs and establish a logical design done only once regardless of the DBMS or computer system that will subsequently use the data.read more

Effect of Data Normalization on Accuracy and Error of Fault Classification for an Electrical Distribution System
TL;DR: Results clearly show significant increase in accuracy of fault classification with considerable reduction in error to classify the faults due to normalization of input data.

A data base sublanguage founded on the relational calculus
TL;DR: Three principal types of language for data base manipulation are identified: the low-level, procedure-oriented, intermediate level, algebraic, and the high level, relational calculus-based data sublanguage, an example of which is described in this paper.
