Evaluation and Comparison of Metrics for XML Schema Languages

The importance of XML (eXtensible Markup Language) can’t be understated; their usefulness may range from data sharing to data transport in software systems. Schema languages describe the structure of an XML document and the common schemas languages are Document Definition Type (DTD), W3C XML Schema and RelaxNG. Applications depend heavily on XML documents to be free of error and this makes it imperative to determine the quality of such schema document. Schema metrics is used to achieve this, and several of them have been proposed in recent years. In this paper we present the existing schema metrics and to make comparative studies on all schema metrics, figuring out the features, advantages and limitations of each metrics

Cloud-Based Security Driven Human Resource Management System

With the emergence of cloud computing, it has become easy to store large volumes of data in the cloud to enhance Human Resource Management (HRM), based on the elasticity and scalability that cloud computing offers. This paper proposes the OnibereOdunayoSecurity-4 (OOS-4) security model for Human Resource Information System (HRIS) deployed on a cloud platform. The OOS-4 framework is a holistic and integrated model that is expected to allow for better interrelatedness of the various components of a HRM organization with adequate consideration for security. Furthermore, utilizing the Platform as a Service (PaaS) cloud computing architecture, the model was implemented using the Google App Engine. The result is a scalable application in which the data in storage is encrypted and visible on the Google Cloud Platform data store. The application is secured by proving encryption for data in storage on the Google Cloud Platform. The application will enhance HRM
