Extreme learning with projection relational algebraic secured data transmission for big cloud data

open access: closedConcurrency and Computation: Practice and Experience
SummaryCloud Computing (CC) and big data are growing technology in the business. Big data is demonstrated in terms of volume, variety, and velocity. CC is employed for storing, processing, and accessing data. Many cryptographic techniques have been developed to enhance big data security in cloud computing.

Projective algebra and the calculus of relations

Journal of Symbolic Logic, 1978
In [1] there were given postulates for an abstract “projective algebra” which, in the words of the authors, represented a “modest beginning for a study of logic with quantifiers from a boolean point of view”. In [5], D. Monk observed that the study initiated in [1] was an initial step in the development of algebraic versions of logic from which have ...

RELAX — the relational algebra pocket calculator project

ACM SIGCSE Bulletin, 2000
Database courses benefit from the abundance of commercial SQL systems available today. Unfortunately, the same cannot be said about the relational algebra query language. This article considers a lab experience to integrate the learning of these two important topics.
