A Phase Approach for Adopting Private Clouds as a Collaborative Platform for Nigerian Universities

Cloud computing is creating a new era for information technology by providing a set of services that appears to have infinite capacity, immediate deployment and high availability at trivial cost. It is the result of the evolution of computing and communications technology from a high-value asset to a simple commodity. In this evolution, the focus shifts from the concept of computing as a physical thing to computing as a service, like electricity, that is accessible from the nearest network connection. An organization, which is under increasing pressure to provide computing services at the lowest possible cost, can choose either public or private clouds to meet these needs. However, driven by concerns over security, regulatory compliance, control over quality of service, and long-term costs, many organizations choose internal private clouds. Private clouds provide the same cost and flexibility benefits as public clouds and also enable an organization to control the quality of service delivered to their users. In addition, private clouds allow an organization to better secure data and meet governance regulations which is usually a major concern when using public clouds. Many universities spend huge amount of money yearly on ICT infrastructure.  About ninety percent of ICTs budgets are consumed by computing requirements that can be centralized and standardized enabling one to do more with less resource. This paper tries to make a ca se for the private cloud as a better platform for collaboration among the Nigerian universities and to propose a safe strategy for migration into the private cloud.

A Frame Work for Data Warehouse for Nigerian Police Force: A Way of Ensuring National Security

Security is presently a major challenge in Nigeria today, Nigerians and non- Nigerians are killed on daily basis and in their numbers. Since the advent of the present democratic dispensation, new forms of violent crimes have become common; these include kidnapping for ransom, pipeline vandalization, Boko Haram bombings, rape, political violence and more. Though the government claims to be on top of the situation, the problem persists. This work attempts to propose a frame work for integration of criminal databases from different state police databases to form a data warehouse for easy access and analysis of criminal data for necessary actions. Data integration involves combining data residing in different sources to form a data warehouse there by providing users with a unified view of these data. Data Integration Technologies have experienced explosive growth in the last few years, and data warehousing has played a major role in the integration process.   Key words: National Security, Data integration, Data Warehousing, Star Schema, Data Mar
