    Education in Nigeria is an instrument for effecting the development of its citizens in particular, and the nation in general. The Universal Basic Education Commission (UBEC) established by UBE Act, 2004 is introduced in Nigeria to ensure unfettered access to nine years of formal basic education as well as reduce the incidence of drop-out from the formal school system through improved relevance and efficiency. In this paper, we design, implement and analyze a secure web-based universal basic educational administrative management system to deal with the problem of administration overload in managing pupils, students, teachers, personnel and curriculum data in both primary and junior secondary schools in Nigeria. We adopt the following sequence to accomplish our goal, requirement analysis, architectural design, application design and implementation. The study explores object-oriented database, PHP (Hypertext Preprocessor), Apache server pages and MySQL DBMS tools. The System prototype is built on a three-tier client server architecture to provide UBEC, primary and junior secondary institutions with broader information availability, better performance, and eliminate internal security problem, paperwork and manpower. The framework will help to improve education capacity building, reliability, robustness and quality. Keywords: Web-based Database, Formal basic Education, Curriculum Data, Object-Oriented Design, Data-Driven System, Universal Basic Education Commission.

    Object-oriented querying of existing relational databases

    In this paper, we present algorithms which allow an object-oriented querying of existing relational databases. Our goal is to provide an improved query interface for relational systems with better query facilities than SQL. This seems to be very important since, in real world applications, relational systems are most commonly used and their dominance will remain in the near future. To overcome the drawbacks of relational systems, especially the poor query facilities of SQL, we propose a schema transformation and a query translation algorithm. The schema transformation algorithm uses additional semantic information to enhance the relational schema and transform it into a corresponding object-oriented schema. If the additional semantic information can be deducted from an underlying entity-relationship design schema, the schema transformation may be done fully automatically. To query the created object-oriented schema, we use the Structured Object Query Language (SOQL) which provides declarative query facilities on objects. SOQL queries using the created object-oriented schema are much shorter, easier to write and understand and more intuitive than corresponding S Q L queries leading to an enhanced usability and an improved querying of the database. The query translation algorithm automatically translates SOQL queries into equivalent SQL queries for the original relational schema

    Technology adoption in the BIM implementation for lean architectural practice

    Justification for Research: the construction companies are facing barriers and challenges in BIM adoption as there is no clear guidance or best practice studies from which they can learn and build up their capacity for BIM use in order to increase productivity, efficiency, quality, and to attain competitive advantages in the global market and to achieve the targets in environmental sustainability. Purpose: this paper aims to explain a comprehensive and systemic evaluation and assessment of the relevant BIM technologies as part of the BIM adoption and implementation to demonstrate how efficiency gains have been achieved towards a lean architectural practice. Design/Methodology/Approach: The research is undertaken through a KTP (Knowledge transfer Partnership) project between the University of Salford and the John McCall Architects based in Liverpool, which is an SME (Small Medium Enterprise). The overall aim of KTP is to develop Lean Design Practice through the BIM adoption and implementation. The overall BIM implementation approach uses a socio-technical view in which it does not only consider the implementation of technology but also considers the socio-cultural environment that provides the context for its implementation. The technology adoption methodology within the BIM implementation approach is the action research oriented qualitative and quantitative research for discovery, comparison, and experimentation as the KTP project with JMA provides an environment for “learning by doing” Findings: research has proved that BIM technology adoption should be undertaken with a bottom-up approach rather than top-down approach for successful change management and dealing with the resistance to change. As a result of the BIM technology adoption, efficiency gains are achieved through the piloting projects and the design process is improved through the elimination of wastes and value generation. Originality/Value: successful BIM adoption needs an implementation strategy. However, at operational level, it is imperative that professional guidelines are required as part of the implementation strategy. This paper introduces a systematic approach for BIM technology adoption based on a case study implementation and it demonstrates a guideline at operational level for other SME companies of architectural practices
