RELATIONAL ALGEBRA IN SQL
Journal Title: INTERNATIONAL JOURNAL OF MATHEMATICS TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 2
Abstract
Relational Algebra is that branch of algebra which deals about set operations on a given relation such as UNION,INTERSECTION,DIFFERENCE,CARTESIAN PRODUCT, PROJECTION ,SELECTION. In this paper we shall discuss these operations in terms of SQL(STRUCTURED QUERY LANGUAGE).

Some Common Fixed Point Theorems Using Implicit Relations in Menger Spaces
In this paper, we prove common fixed point theorems for pairs of weakly compatible mappings along with E.A. and (CLRS) properties using implicit relations in Menger spaces.
A Study on the Queue Length of the State-Dependent of an Unreliable Machine
In this paper, we consider a state-dependent queueing system in which the machine is subject to random breakdowns. Jobs arrive at the system randomly following a Poisson process with state-dependent rates. Service times...
Asymptotic Behavior of Solutions for Forced Non Linear Delay Impulsive Differential Equations
We establish new sufficient conditions for asymptotic behavior of the solutions of non linear forced neutral delay differential equations with constant impulsive jumps. Our results improve and generalize some known resul...
The Attitude of some Nigerian Science, Technology, and Mathematics Teachers towards Assessment Practices
The study investigated the attitudes of 305 Science, Technology and Mathematics (STM) teachers towards assessment practices in Nigeria. The sample was selected through stratified and random sampling techniques from...
On Normed Space Valued Total Paranormed Orlicz Space of Null Sequences and its Topological Structures
In this paper,we introduce and study a new class c0 (S, M, u–) of normed space S valued sequences using Orlicz function M as a generalization of basic space of null complex sequences c0. Beside the investigation pertaini...
