Usually, a healthcare dataset may contain irrelevant, redundant, and noisy features; applying classification algorithms to such type of data may produce a less accurate and a less understandable results. Therefore, selection of optimal features has a significant influence on enhancing the accuracy of classification systems. Feature selection method is an effective data pre-processing technique in data mining, which can be used to identify a minimum set of features. This type of technique has immediate effects on speeding up classification algorithms and improving performance such as predictive accuracy. This paper, aims to evaluate the performance of five different classification methods including: C5.0, R...

Majority of the companies, organizations and teaching and learning institutions store sensitive data in databases .As most of these data are electronically accessed , It can therefore be assumed that , the integrity of these numerous and sensitive data is prone to different kind of threat such as{Unauthorized access, theft as well access denial}. Therefore, the need for securing databases has also increased The primary objectives of database security are to prevent unauthorized access to data, prevent unauthorized tampering or modification of data, and to also ensure that, these data remains available whenever needed. In this paper, we developed a database security framework by combining different security mechanism on a sensitive students information database application designed for Shehu Shaga...
